Claims
- 1. A method for synthesizing a composition of matter comprising an inorganic, porous, non-layered crystalline phase material exhibiting, after calcination, an X-ray diffraction pattern with at least one peak at a d-spacing greater than about 18 Angstrom Units with a relative intensity of 100 and a benzene adsorption capacity of greater than 15 grams benzene per 100 grams of said material at 50 torr and 25.degree. C., said method comprising the steps of:
- (a) preparing a mixture capable of forming said composition, said mixture comprising a source of silica, a source of alumina, an organic (R') agent and a solvent or solvent mixture, wherein R' comprises an ion of the formula R.sub.1 R.sub.2 R.sub.3 R.sub.4 Q.sup.+, wherein Q is nitrogen or phosphorus and wherein at least one of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 is aryl or alkyl of from 6 to about 36 carbon atoms or combinations thereof, the remainder of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 being selected from the group consisting of hydrogen, alkyl of from 1 to 5 carbon atoms and combinations thereof;
- (b) maintaining said mixture under sufficient conditions of pH, temperature and time for formation of said composition of matter; and
- (c) recovering said composition of matter, wherein said source of silica and said source of alumina comprise hydrolyzable compounds which hydrolyze under the conditions of step (b) to give silica and alumina.
- 2. A method according to claim 1, wherein said hydrolyzable silicon and aluminum compounds comprise alkoxide moieties, and wherein said reaction mixture is heated under conditions sufficient to evaporate alcohol produced by the hydrolysis reaction.
- 3. A method according to claim 2, wherein water is added to the reaction mixture after hydrolysis of said hydrolyzable silicon and aluminum compounds.
- 4. A method according to claim 3, wherein said step (b) comprises heating the mixture of step (a) for at least one hour at a temperature of at least 100.degree. C.
- 5. A method according to claim 4, wherein said hydrolyzable silicon compound is tetraethylorthosilicate and said hydrolyzable aluminum compound is aluminum (iso-propoxide).sub.2 acetoacetic ester chelate.
