Description

[0001] The present invention relates to a novel class of shaped bodies containing metal-organic frameworks. Said metal-organic frameworks comprise at least one metal ion and at least one at least bidentate organic compound and at least one type of micro- and mesopores or micro- or mesopores. Said shaped bodies comprise at least one metal-organic framework material and may optionally contain further substances, in particular at least one supporting material.

[0002] Materials displaying a large internal surface area, preferably defined by pores or channels, are of predominant interest for applications in catalysis, for absorption and/or adsorption techniques, ion exchanging, chromatography, storage and/or uptake of substances, among others. The preparation of solid porous materials according to the present state of the art is described, for example, in Preparation of Solid Catalysts, Gerhard Ertl, Helmut Knözinger, Jens Weitkamp (Eds.), Wiley VCH, Weinheim, 1999. Here, solid porous materials are prepared by precipitation, sol-gel processes, spray-drying, foaming etc.

[0003] In a promising novel and alternative synthesis strategy to create micro- and/or mesoporous active materials, metal ions and molecular organic building blocks are used to form so-called metal-organic frameworks (MOFs). The metal-organic framework materials as such are described, for example, in U.S. Pat. No. 5,648,508, EP-A-0 709 253, M. O'Keeffe et al., J. Sol. State Chem., 152 (2000) p. 3-20, H. Li et al., Nature 402 (1999) p. 276 seq., M. Eddaoudi et al., Topics in Catalysis 9 (1999) p. 105-111, B. Chen et al., Science 291 (2001) p. 1021-23. Among the advantages of these novel materials, in particular for applications in catalysis, are the following: (i) larger pore sizes can be realized than for the zeolites used presently (ii) the internal surface area is larger than for porous materials used presently (iii) pore size and/or channel structure can be tailored over a large range, (iv) the organic framework components forming the internal surface can be functionalized easily.

[0004] However these novel porous materials as such, based on metal-organic frame-works, are generally obtained as small crystallites or powders and—in this form—cannot be put to use in applications that require shaped bodies.

[0005] It is therefore an object of the present invention to provide a shaped body displaying the characteristic properties of the materials containing metal-organic frameworks. The term “shaped body” as used in the present invention thereby refers to shaped bodies obtained by molding processes and to shaped bodies obtained by applying the active material onto a (porous) substrate. The term “shaped body” will be defined further below.

[0006] This object is solved by subjecting at least one material containing a metal-organic framework comprising pores and at least one metal ion and at least one at least bidentate organic compound, which is coordinately bound to said metal ion, to a molding step or to apply said material onto a substrate or to perform a combination of both operations. Thus, the present invention relates to a metal-organic framework material comprising pores and at least one metal ion and at least one at least bidentate organic compound, which is coordinately bounded to said metal ion characterized in that it is in the form of a shaped body, a process for manufacturing the metal-organic framework material that is in the form of a shaped body as described herein, characterized in that the shaped body is obtained by at least one step of molding, a process for manufacturing a metal-organic framework material that is in the form of a shaped body as described herein, characterized in that the shaped body is obtained by contacting at least one metal-organic frame-work material with at least one substrate, and the use of said framework materials as described herein, as catalyst, support for catalysts, for sorption, storage of fluids; as desiccant, ion exchanger material, molecular sieve (separator), material for chromatography, material for the selective release and/or uptaking of molecules, molecular recognition, nanotubes, nano-reactors.

[0007] As has been mentioned above, the metal-organic framework material is described in, for example, U.S. Pat. No. 5,648,508, EP-A-0 709 253, M. O'Keeffe et al., J. Sol. State Chem., 152 (2000) p. 3-20, H. Li et al., Nature 402 (1999) p. 276 seq., M. Eddaoudi et al., Topics in Catalysis 2 (1999) p. 105-111,B. Chen et al., Science 291 (2001) p. 1021-23. An inexpensive way for the preparation of said materials is the subject of DE 10111230.0. The content of these publications, to which reference is made herein, is fully incorporated in the content of the present application.

[0008] The metal-organic framework materials, as used in the present invention, comprise pores, particularly micro- and/or mesopores. Micropores are defined as being pores having a diameter of 2 nm or below and mesopores as being pores having a diameter in the range of 2 nm to 50 nm, according to the definition given in Pure Applied Chem. 45, p. 71 seq., particularly on p. 79 (1976). The presence of the micro- and/or mesopores can be monitored by sorption measurements which determine the capacity of the metal-organic framework materials for nitrogen uptake at 77 K according to DIN 66131 and/or DIN 66134.

[0009] For example, a type-I-form of the isothermal curve indicates the presence of micropores [see, for example, paragraph 4 of M. Eddaoudi et al., Topics in Catalysis 2 (1999)]. In a preferred embodiment, the specific surface area, as calculated according to the Langmuir model (DIN 66131, 66134) preferably is above 5 m2/g, further preferred above 10 m2/g, more preferably above 50 m2/g, particularly preferred above 500 m2/g and may increase into the region above 3000 m2/g.

[0010] As to the metal component within the framework material that is to be used according to the present invention, particularly to be mentioned are the metal ions of the main group elements and of the subgroup elements of the periodic system of the elements, namely of the groups Ia, Ia, IIIa, IVa to VIIIa and Ib to VIb. Among those metal components, particular reference is made to Mg, Ca, Sr, Ba, Sc, Y, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn, Re, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au, Zn, Cd, Hg, Al, Ga, In, Tl, Si, Ge, Sn, Pb, As, Sb, and Bi, more preferably to Zn, Cu, Ni, Pd, Pt, Ru, Rh and Co. As to the metal ions of these elements, particular reference is made to: Mg2+, Ca2+, Sr2+, Ba2+, Sc3+, Y3+, Ti4+, Zr4+, Hf4+, V4+, V3+, V2+, Nb3+, Ta3+, Cr3+, Mo3+, W3+, Mn3+, Mn2+, Re3+, Re2+, Fe3+, Fe2+, Ru3+, Ru2+, Os3+, Os2+, Co3+, Co2+, Rh2+, Rh30 , Ir2+, Ir+, Ni2+, Ni+, Pd2+, Pd+, Pt2+, Pt+, Cu2+, Cu+, Ag+, Au+, Zn2+, Cd2+, Hg2+, Al3+, Ga3+, In3+, Tl3+, Si4+, Si2+, Ge4+, Ge2+, Sn4+, Sn2+, Pb4+, Pd2+, As5+, As3+, As+, Sb5+, Sb3+, Sb+, Bi5+, Bi3+ and Bi+.

[0011] With regard to the preferred metal ions and further details regarding the same, particular reference is made to: EP-A 0 790 253, particularly to p. 10, 1. 8-30, section “The Metal Ions”, which section is incorporated herein by reference.

[0012] In addition to the metal salts disclosed in EP-A 0 790 253 and U.S. Pat. No. 5,648,508, other metallic compounds can be used, such as sulfates, phosphates and other complex counter-ion metal salts of the main- and subgroup metals of the periodic system of the elements. Metal oxides, mixed oxides and mixtures of metal oxides and/or mixed oxides with or without a defined stoichiometry are preferred. All of the above mentioned metal compounds can be soluble or insoluble and they may be used as starting material either in form of a powder or as a shaped body or as any combination thereof.

[0013] As to the at least bidentate organic compound, which is capable of coordination with the metal ion, in principle all compounds can be used which are suitable for this purpose and which fulfill the above requirements of being at least bidentate. Said organic compound must have at least two centers, which are capable to coordinate the metal ions of a metal salt, particularly with the metals of the aforementioned groups. With regard to the at least bidentate organic compound, specific mention is to be made of compounds having

[0018] Particularly to be mentioned are substituted or unsubstituted, mono- or polynuclear aromatic di-, tri- and tetracarboxylic acids and substituted or unsubstituted, at least one hetero atom comprising aromatic di-, tri- and tetracarboxylic acids, which have one or more nuclei.

[0019] A preferred ligand is 1,3,5-benzene tricarboxylic acid (BCT). Further preferred ligands are ADC (acetylene dicarboxylate), NDC (naphtalene dicarboxylate), BDC (benzene dicarboxylate), ATC (adamantane tetracarboxylate), BTC (benzene tricarboxylate), BTB (benzene tribenzoate), MTB (methane tetrabenzoate) and ATB (adamantane tribenzoate).

[0020] Besides the at least bidentate organic compound, the framework material as used in accordance with the present invention may also comprise one or more monodentate ligand(s), which is/are preferably selected from the following monodentate substances and/or derivatives thereof:

[0021] a. alkyl amines and their corresponding alkyl ammonium salts, containing linear, branched, or cyclic aliphatic groups, having from 1 to 20 carbon atoms (and their corresponding ammonium salts);

[0022] b. aryl amines and their corresponding aryl ammonium salts having from 1 to 5 phenyl rings;

[0024] d. aryl phosphonium salts, having from 1 to 5 phenyl rings;

[0025] e. alkyl organic acids and the corresponding alkyl organic anions (and salts) containing linear, branched, or cyclic aliphatic groups, having from 1 to 20 carbon atoms;

[0026] f. aryl organic acids and their corresponding aryl organic anions and salts, having from 1 to 5 phenyl rings;

[0032] Further details regarding the at least bidentate organic compounds and the monodentate substances, from which the ligands of the framework material as used in the present application are derived, can be taken from EP-A 0 790 253, whose respective content is incorporated into the present application by reference.

[0033] Within the present application, framework materials of the kind described herein, which comprise Zn2+ as a metal ion and ligands derived from terephthalic acid as the bidentate compound, are particularly preferred. Said framework materials are known as MOF-5 in the literature.

[0034] Further metal ions, at least bidentate organic compounds and mono-dentate substances, which are respectively useful for the preparation of the framework materials used in the present invention as well as processes for their preparation are particularly disclosed in EP-A 0 790 253, U.S. Pat. No. 5,648,508 and DE 10111230.0.

[0035] As solvents, which are particularly useful for the preparation of MOF-5, in addition to the solvents disclosed in the above-referenced literature, dimethyl formamide, diethyl formamide and N-methylpyrollidone, alone, in combination with each other or in combination with other solvents may be used. Within the preparation of the framework materials, particularly within the preparation of MOF-5, the solvents and mother liquors are recycled after crystallization in order to save costs and materials.

[0036] The pore sizes of the metal-organic framework can be adjusted by selecting suitable organic ligands and/or bidendate compounds (=linkers). Generally, the larger the linker, the larger the pore size. Any pore size that is still supported by a the metal-organic framework in the absence of a host and at temperatures of at least 200° C. is conceivable. Pore sizes ranging from 0.2 nm to 30 nm are preferred, with pore sizes ranging from 0.3 nm to 3 nm being particularly preferred.

[0037] In the following, examples of metal-organic framework materials (MOFs) are given to illustrate the general concept given above. These specific examples, however, are not meant to limit the generality and scope of the present application.

[0038] By way of example, a list of metal-organic framework materials already synthesized and characterized is given below. This also includes novel isoreticular metal organic framework materials (IR-MOFs), which may be used in the framework of the present application. Such materials having the same framework topology while displaying different pore sizes and crystal densities are described, for example in M. Eddouadi et al., Science 295 (2002) 469, which is incorporated into the present application by reference.

[0039] The solvents used are of particular importance for the synthesis of these materials and are therefore mentioned in the table. The values for the cell parameters (angles α, β and γ as well as the spacings a, b and c, given in Angstrom) have been obtained by x-ray diffraction and represent the space group given in the table as well.

[0040] Examples for the synthesis of these materials as such can, for example, be found in: J. Am. Chem. Soc. 123 (2001) pages 8241 seq. or in Acc. Chem. Res. 31 (1998) pages 474 seq., which are fully encompassed within the content of the present application with respect to their respective content.

[0041] The separation of the framework materials, particularly of MOF-5, from the mother liquor of the crystallization may be achieved by procedures known in the art such as solid-liquid separations, centrifugation, extraction, filtration, membrane filtration, cross-flow filtration, flocculation using flocculation adjuvants (non-ionic, cationic and anionic adjuvants) or by the addition of pH shifting additives such as salts, acids or bases, by flotation, as well as by evaporation of the mother liquor at elevated temperature and/or in vacuo and concentrating of the solid. The material obtained in this step is typically a fine powder and cannot be used for most practical applications, e.g., in catalysis, where shaped bodies are required.

[0042] In the context of the present invention, the term “shaped body” refers to any solid body that has at least a two-dimensional outer contour and extends to at least 0.02 mm in at least one direction in space. No other restrictions apply, i.e., the body may take any conceivable shape and may extend in any direction by any length so long as it extends to at least 0.02 mm in one direction. In a preferred embodiment, the shaped bodies do not extend to more than 50 mm and not to less than 0.02 mm in all directions. In a further preferred embodiment, this range is limited from 1.5 mm to 5 mm.

[0043] As far as the geometry of these shaped bodies is concerned, spherical or cylindrical bodies are preferred, as well as disk-shaped pellets or any other suitable geometry. such as honeycombs, meshes, hollow bodies, wire arrangements etc.

[0044] To form shaped bodies containing an active material, for example a catalytically active material, several routes exist. Among them

[0045] (i) molding the active material alone or the active material in combination with a binder and/or other components into a shaped body, for example by pelletizing;

[0046] (ii) applying the active material onto a (porous) substrate, and

[0047] (iii) supporting an active material on a porous or non-porous substrate which is then molded into a shaped body

[0048] are to be mentioned.

[0049] Although not limited with regard to the route to obtain shaped bodies comprising metal-organic frameworks according to the present invention, the above-recited routes are preferred within the invention disclosed herein. Presently, zeolites are the most commonly used porous active materials that are either molded into shaped bodies or applied onto a (porous) support.

[0050] For the step of preparing shaped bodies containing at least one metal-organic framework material, all processes of molding a powder and/or crystallites together that are known to the expert are conceivable. Also, all processes of applying an active component, such as the metal-organic framework material, onto a substrate are conceivable. Preparing shaped bodies by a process involving molding is described first, followed by a description of the process of applying said material onto a (porous) substrate.

[0051] In the context of the present invention, the term “molding” refers to any process known to the expert in the field by which a substance that does not fulfill the above-mentioned requirement of a shaped body, i.e. any powder, powdery substance, array of crystallites etc., can be formed into a shaped body that is stable under the conditions of its intended use.

[0052] While the step of molding at least one metal-organic framework material into a shaped body is mandatory, the following steps are optional according to the present invention:

[0053] (I) the molding may be preceded by a step of mixing,

[0054] (II) the molding may be preceded by a step of preparing a paste-like mass or a fluid containing the metal-organic framework, for example by adding solvents, binders or other additional substances,

[0055] (III) the molding may be followed by a step of finishing, in particular a step of drying.

[0056] The mandatory step of molding, shaping or forming may be achieved by any method known to expert to achieve agglomeration of a powder, a suspension or a paste-like mass. Such methods are described, for example, in Ullmann's Enzylopädie der Technischen Chemie, 4th Edition, Vol. 2, p. 313 et seq., 1972, whose respective content is incorporated into the present application by reference.

[0057] In general, the following main pathways can be discerned: (i) briquetting, i.e. mechanical pressing of the powdery material, with or without binders and/or other additives, (ii) granulating (pelletizing), i.e. compacting of moistened powdery materials by subjecting it to rotating movements, and (iii) sintering, i.e. subjecting the material to be compacted to a thermal treatment. The latter is somewhat limited for the material according to the invention due to the limited temperature stability of the organic materials (see discussion below).

[0058] Specifically, the molding step according to the invention is preferably performed by using at least one method selected from the following group: briquetting by piston presses, briquetting by roller pressing, binderless briquetting, briquetting with binders, pelletizing, compounding, melting, extruding, co-extruding, spinning, deposition, foaming, spray drying, coating, granulating, in particular spray granulating or granulating according to any process known within the processing of plastics or any combination of at least two of the aforementioned methods.

[0059] The preferred processes of molding are those in which the molding is affected by extrusion in conventional extruders, for example such that result in extrudates having a diameter of, usually, from about 1 to about 10 mm, in particular from about 1.5 to about 5 mm. Such extrusion apparatuses are described, for example, in Ullmann's Enzylopädie der Technischen Chemie, 4th Edition, Vol. 2, p. 295 et seq., 1972. In addition to the use of an extruder, an extrusion press is preferably also used for molding.

[0060] The molding can be performed at elevated pressure (ranging from atmospheric pressure to several 100 bar), at elevated temperatures (ranging from room temperature to 300° C.) or in a protective atmosphere (noble gases, nitrogen or mixtures thereof). Any combinations of these conditions is possible as well.

[0061] The step of molding can be performed in the presence of binders and/or other additional substances that stabilize the materials to be agglomerated. As to the at least one optional binder, any material known to expert to promote adhesion between the particles to be molded together can be employed. A binder, an organic viscosity-enhancing compound and/or a liquid for converting the material into a paste can be added to the metal-organic framework material, with the mixture being subsequently compacted in a mixing or kneading apparatus or an extruder. The resulting plastic material can then be molded, in particular using an extrusion press or an extruder, and the resulting moldings can then be subjected to the optional step (III) of finishing, for example drying.

[0062] A number of inorganic compounds can be used as binders. For example, according to U.S. Pat. No. 5,430,000, titanium dioxide or hydrated titanium dioxide is used as the binder. Examples of further prior art binders are:

[0063] hydrated alumina or other aluminum-containing binders (WO 94/29408);

[0064] mixtures of silicon and aluminum compounds (WO 94/13584);

[0065] silicon compounds (EP-A 0 592 050);

[0066] clay minerals (JP-A 03 037 156);

[0067] alkoxysilanes (EP-B 0 102 544);

[0068] amphiphilic substances;

[0069] graphite.

[0070] Other conceivable binders are in principle all compounds used to date for the purpose of achieving adhesion in powdery materials. Compounds, in particular oxides, of silicon, of aluminum, of boron, of phosphorus, of zirconium and/or of titanium are preferably used. Of particular interest as a binder is silica, where the Sio2 may be introduced into the shaping step as a silica sol or in the form of tetraalkoxysilanes. Oxides of magnesium and of beryllium and clays, for example montmorillonites, kaolins, bentonites, halloysites, dickites, nacrites and anauxites, may furthermore be used as binders. Tetraalkoxysilanes are particularly used as binders in the present invention. Specific examples are tetramethoxysilane, tetraethoxysilane, tetrapropoxysilane and tetrabutoxysilane, the analogous tetraalkoxytitanium and tetraalkoxyzirconium compounds and trimethoxy-, triethoxy-, tripropoxy- and tributoxy-aluminum, tetramethoxysilane and tetraethoxysilane being particularly preferred.

[0071] In addition, organic viscosity-enhancing substances and/or hydrophilic polymers, e.g. cellulose or polyacrylates may be used. The organic viscosity-enhancing substance used may likewise be any substance suitable for this purpose. Those preferred are organic, in particular hydrophilic polymers, e.g., cellulose, starch, polyacrylates, polymethacrylates, polyvinyl alcohol, polyvinylpyrrolidone, polyisobutene and polytetrahydrofuran. These substances primarily promote the formation of a plastic material during the kneading, molding and drying step by bridging the primary particles and moreover ensuring the mechanical stability of the molding during the molding and the optional drying process.

[0072] There are no restrictions at all with regard to the optional liquid which may be used to create a paste-like substance, either for the optional step (I) of mixing or for the mandatory step of molding. In addition to water, alcohols may be used, provided that they are water-miscible. Accordingly, both monoalcohols of 1 to 4 carbon atoms and water-miscible polyhydric alcohols may be used. In particular, methanol, ethanol, propanol, n-butanol, isobutanol, tert-butanol and mixtures of two or more thereof are used.

[0073] Amines or amine-like compounds, for example tetraalkylammonium compounds or aminoalcohols, and carbonate-containing substances, such as calcium carbonate, may be used as further additives. Such further additives are described in EP-A 0 389 041, EP-A 0 200 260 and WO 95/19222, which are incorporated fully by reference in the context of the present application.

[0074] Most, if not all, of the additive substances mentioned above may be removed from the shaped bodies by drying or heating, optionally in a protective atmosphere or under vacuum. In order to keep the metal-organic framework intact, the shaped bodies are preferably not exposed to temperatures exceeding 300° C. However, studies show that heating/drying under the aforementioned mild conditions, in particular drying in vacuo, preferably well below 300° C. is sufficient to at least remove organic compounds out of the pores of the metal-organic framework (see the references given with respect to metal-organic frameworks above). Generally, the conditions are adapted and chosen depending upon the additive substances used.

[0075] The order of addition of the components (optional solvent, binder, additives, material with a metal-organic framework) is not critical. It is possible either to add first the binder, then, for example, the metal-organic framework material and, if required, the additive and finally the mixture containing at least one alcohol and/or water or to interchange the order with respect to any of the aforementioned components.

[0076] As far as the optional step (I) of mixing is concerned, for example, of the material containing a metal-organic framework and a binder and optionally further process materials (=additional materials), all methods known to the expert in the fields of materials processing and unit operations can be used. If the mixing occurs in the liquid phase, stirring is preferred, if the mass to be mixed is paste-like, kneading and/or extruding are preferred and if the components to be mixed are all in a solid, powdery state, mixing is preferred. The use of atomizers, sprayers, diffusers or nebulizers is conceivable as well if the state of the components to be used allows the use thereof. For paste-like and powder-like materials the use of static mixers, planetary mixers, mixers with rotating containers, pan mixers, pug mills, shearing-disk mixers, centrifugal mixers, sand mills, trough kneaders, internal mixers, internal mixers and continuous kneaders are preferred. It is explicitly included that a process of mixing may be sufficient to achieve the molding, i.e., that the steps of mixing and molding coincide.

[0077] The shaped body according to the invention is preferably characterized by at least one of the following properties:

[0078] (i) it extends in at least one direction in space by at least 0.02 mm and that it does not extend in any direction in space by more than 50 mm.

[0079] (ii) it is pellet shaped and has a diameter in the range from 1.5 mm to 5 mm and a height in the range from 1 mm to 5 mm.

[0080] (iii) it has a resistance to pressure (crush strength) in the range from 2 N to 100 N.

[0081] As a second principal pathway for producing shaped bodies containing at least one metal-organic framework material, applying said material to a substrate is part of the present invention. Preferably, the substrate is porous. In principle, all techniques for contacting said material with said substrate are conceivable. Specifically, all techniques used for contacting an active material with a porous substrate known from the preparation of catalysts are applicable.

[0082] The at least one method of contacting is selected from the group comprising impregnating with a fluid, soaking in a fluid, spraying, depositing from the liquid phase, depositing from gas phase (vapor deposition), precipitating, co-precipitating, dipping-techniques, coating.

[0083] As a porous substrate, each shaped body known to the expert can be used, so long as the shaped body fulfills the general requirements concerning its geometry as specified in the present application, for example, in the points (i) to (iii) given above. Specifically, the porous substrate that will be contacted with the metal-organic framework material can be selected from the following group containing alumina, activated alumina, hydrated alumina, silica gels, silicates, diatomite, kaolin, magnesia, activated charcoal, titanium dioxide, zeolites.

[0084] While porous substrates are the preferred embodiment, contacting of the active material (metal-organic framework) with a nonporous body and/or a two-dimensional substrate are conceivable as well. In the case of applying a catalytically active material onto a non-porous shaped body, shell catalysts are obtained. Such configurations, as well as monolithic embodiments are explicitly included in the present invention, so long as they contain at least one metal-organic frame-work material.

[0085] Other embodiments customary in catalyst technologies such as application of the active substance in a washcoat and/or structuring the support in honeycombs or in channels or other skeleton-shapes are preferred.

[0086] The shaped bodies according to the invention can be used in any process known to the expert in which a porous body or a body with channels or a porous body with channels provides an advantage over solid bodies or powders. In particular, such applications include: catalysts, support for catalysts, sorption, storage of fluids, desiccants, ion exchanger materials, molecular sieves (separators), materials for chromatography, materials for the selective release and/or uptaking of molecules, molecular recognition, nanotubes, nano-reactors.

[0087] In a preferred application, the shaped bodies according to the invention are used as catalysts in fixed bed/packed bed reactors. In principle, said shaped bodies can be used in gas phase reactions or in liquid phase reactions, in which case the solid shaped bodies are suspended in a slurry. In principle, the shaped bodies according to the invention can be used to catalyze all reactions known to the expert in which the presence of channels and/or pores and/or active centers incorporated therein are known or believed to increase the activity and/or selectivity and/or yield of said reaction.

[0088] The invention is now further described by way of the following examples, which are, however, not meant to limit the scope of the present application.

EXAMPLE 1

[0089] (Preparation of MOF-5)

	Molar
Starting Material	Amount	Calculated	Experimental
terephthalic acid	12.3 mmol	2.04 g	2.04 g
zinc nitrate-tetra hy-	36.98 mmol	9.67 g	9.68 g
drate
diethylformamide	2568.8 mmol	282.2 g	282.2 g
(Merck)

[0090] The respective amounts of the starting materials given in the table above were placed in a beaker in the order diethylformamide, terephthalic acid and zinc nitrate. The resulting solution was introduced into two autoclaves (250 ml), having inner walls which were covered by teflon.

[0091] The crystallization occurred at 105° C. and within twenty hours. Subsequently, the orange solvent was decanted from the yellow crystals, said crystals were again covered by 20 ml dimethylformamide, the latter again being decanted. This procedure was repeated three times. Subsequently, 20 ml chloroform were poured onto the solid, which was washed and decanted by said solvent two times.

[0092] The crystals (14.4 g), which were still moist, were introduced into a vacuum device and first dried at room temperature in vacuo (10−4 mbar). Afterwards, they were dried at 120° C.

[0093] Subsequently, the resulting product was characterized by X-ray powder diffraction and an adsorptive determination of micropores. The determination of the sorption isotherm with argon (87K; Micromeritics ASAP 2010) shows an isotherm of the type I, being characteristic of microporous materials and having a specific surface area of 3020 m2/g, calculated according to Langmuir, as well as a micropore volume of 0.97 ml/g (at a relative pressure of p/p0=0.4).

EXAMPLE 2

[0094] (Preparing Pellets Containing MOF-5)

[0095] Pressing of the pellets according to the invention was performed by means of an eccentric press as provided by Korsch (Type EK0). Here, the pellet-forming tool was chosen to be a matrix with a hole of a diameter of 4.75 mm, thus leading to pellets of 4.75 mm diameter. The mixture that was fed into the eccentric press consisted of 99.8% MOF-2 and 0.2% graphite, namely of 49.9 g MOF-5 powder and 0.1 g graphite. The two components have been mixed thoroughly in a mixing flask. The procedure was performed under nitrogen atmophere.

[0096] The adjustments of the eccentric press were as follows: (i) filling height: 10 mm, (ii) penetrating depth of the upper stamp: 7 mm and (iii) rounds per minute of the rotor: 20.

[0097] The shape of the pellet was as follows: (i) diameter: 4.75 mm and (ii) height: 3 mm.

[0098] After the pellet-forming, the lateral pressure resistance to pressure (crush strength) was measured with a hardness grading device by Zwick to be 10 N/pellet with a standard deviation of 0.8 N/pellet.
