Oligomerization catalysts and process using the same for the production of olefinic oligomers

CROSS-REFERENCE TO RELATED APPLICATION
This application is a 35 U.S.C. .sctn.371 filing of International Application No. PCT/JA96/00532, filed 6 Mar. 1996.
FIELD OF THE INVENTION
This invention relates to catalysts useful for oligomerization of .alpha.-olefins and a process using the same for the production of .alpha.-olefinic oligomers.
BACKGROUND OF THE ART
Transition metal compounds have been widely used as the catalysts for oligomerization of olefins.
Japanese Patent Publication No. 47-49561 discloses the use of catalysts comprising nickel compounds, phosphine compounds and halogen-containing organoaluminum compounds for dimerization of lower olefins. The disclosed process is imposed with a restriction that the catalysts have to be prepared in the presence of lower olefins (gaseous) to be dimerized and further has a drawback in that the catalysts are not adequately stable or sometimes deficient in their activity, leading to reduced dimer yields (catalytic activity) for a given amount of catalyst.
Japanese Patent Publication No. 62-19408 discloses catalysts comprising nickel compounds, bis-dialuminoxanes and halogenated phenols for use in dimerizing .alpha.-olefins. The catalysts disclosed therein are superior to those disclosed in Patent Publication No. 47-49561 in respect of catalytic activity and stability, but have the difficulty that when used for a propylene feedstock, they are prone to by-produce large quantities of trimers with a dimer selectivity reduced to the order of 50%-70%.
Whereas, it is an object of the present invention to provide a novel oligomerization catalyst capable of selectively producing .alpha.-olefinic dimers at an increased rate of yield.
It is another object of the invention to provide a process using the above inventive catalyst for the production of .alpha.-olefinic oligomers.

The process of the invention is characterized by the use of the above described catalysts for the oligomerization of .alpha.-olefins.
The .alpha.-olefins, i.e. the starting monomer, have a carbon number of 2-12, preferably 2-8, including ethylene, propylene, 1-butene, isobutene, 1-pentene, 1-hexene, 3-methyl-1-pentene, 4-methyl-1-pentene, 1-octene and 1-decene, of which ethylene and propylene are preferred and propylene is more particularly preferred.
The oligomerization catalyst may be varied in its concentration depending upon the mode of reaction employed which may be solution reaction, gas-phase reaction, bulk reaction, etc. In the case of solution reaction, the concentrations of the catalyst may be, by nickel conversion, in the range of from 0.0001 millimol to 100 mole, preferably 0.001 millimol to 1 mol, more preferably 0.01 millimol to 100 millimole per liter of solvent.
The oligomerization reaction is effected at a temperature of from minus 100.degree. C. to plus 200.degree. C., preferably minus 50.degree. C. to plus 100.degree. C., more preferably 0.degree. C. to 50.degree. C. and as a pressure, of from 10 kPa.G to 10 MPa.G, preferably 100 kPa.G to 5 MPa.G,more preferably 200 kPa.G to 3 MPa.G. Reaction time lengths are not normally restricted, but may be from 1 minute to 1 week with a batch mode reaction and from 1 second to 6 hours with a continuous mode reaction in which both feedstock and catalyst are fed continuously while the reaction product is continuously withdrawn.
It has been found that a solution polymerization mode of reaction is particularly useful with use of a solvent of the kind which is free from adversely affecting the inventive oligomerization catalyst and which may be such solvents that are used in the preparation of the inventive catalyst, or it may alternatively be a starting monomer for oligomerization.
The oligomerization reaction according to the invention is initiated by introducing the catalyst and a given .alpha.-olefin feedstock into a pressure vessel, the feedstock being normally (at 0.degree. C. and 1 atmospheric) gaseous or liquid. Upon completion of the reaction, the vessel is depressurized and released in the air, followed by washing the reaction product with dilute chloric acid and then with saturated salt water and finally by drying the product with magnesium sulfate. Distillation is preferred for refining the product.
There may be produced various .alpha.-olefinic oligomers, but dimers in particular can be produced with a high rate of selectively according to the invention. For example, there may be produced 1-butene and 2-butene from ethylene, and 1-hexene, 2-hexene, 2-methyl-1-pentene, 2-methyl-2-pentene, 4-methyl-1-pentene, 4-methyl-2-pentene, 2,3-dimethyl-1-butene and 2,3-dimethyl-2-butene from propylene.
Industrial Utility of the Invention
The inventive catalyst is highly industrially useful as it is capable of selectively producing dimer products, particularly propylene oligomers of an unsaturated C.sub.6 composition comprising chiefly 2,3-dimethyl-1-butene and 2,3-dimethyl-2-butene and containing hexenes andmethylpentenes. The resulting product is useful as a gasoline blend or octane improver. The C.sub.6 composition may be hydrogenated to provide a 2,3-dimethylbutane-rich product for use as a high-performance gasoline blend or octane improver.
The invention will be further described by way of the following examples which should be regarded only as illustrative, not in a limiting sense.

Upon completion of the reaction, propylene was expelled and the reaction solution was washed withdilute chloric acid and saturated salt water, followed by drying with anhydrous magnesium sulfate. The reaction product was gas-chromatographically analyzed with the results shown below wherein selectivity of dimethylbutene, methylpentene and hexene, respectively, is given by percentage on the basis of total dimers (100%).

INVENTIVE EXAMPLE 48
A 500 ml autoclave equipped with an electromagnetic stirrer and fully driedwas charged under nitrogen atmosphere with 40 ml dry toluene, a toluene solution (0.1 mmol) of nickel naphthenate, 2-methfylbutadiene (23 mmole) and triisopropylphosphine (0.1 mmol) while being stirred, followed by addition of a toluene solution (1.1 mmole) of ethylaluminum sesquichloride, n-decane (10 ml) as an internal reference compound and diethylzinc (0.1 mmol).

INVENTIVE EXAMPLE 49
The procedure of Inventive Example 41 was followed except that a butanol solution of (Zr:Butanol=1:1 mol) tetrabutoxy zirconium (0.1 mmol) was usedin place of a toluene solution of tetrabutoxy zirconium (0.1 mmol).

INVENTIVE EXAMPLE 50
A 500 ml autoclave equipped with an electromagnetic stirrer and fully driedwas charged under nitrogen atmosphere with 40 ml dry toluene, nickel 2-ethylhexanate (0.1 mmol), vinylnorbornene (0.5 mmol) and triisopropylphosphine (0.1 mmol) while being stirred, followed by additionof a toluene solution (1.1 mmole) of ethylaluminum sesquichloride, n-decane(10 ml) as an internal reference compound and sodium tetraphenylborate (0.01 mmol).
The admixture was stirred at 40.degree. C. for 5 minutes, to which propylene feedstock was added. The reaction was continued for 1 hour with the system pressure maintained at 686 kPa.G. Upon completion of the reaction, propylene was expelled and the reaction solution was washed withdilute chloric acid and saturated salt water, followed by drying with anhydrous magnesium sulfate.
