Abstract:
A process for producing a synthetic porous crystalline material having the X-ray diffraction lines listed in Table I comprising the steps of:(a) forming a reaction mixture containing sources of alkali or alkaline earth metal (M) cations, an oxide of a trivalent element (X), an oxide of a tetravalent element (Y), a directing agent (R) and water, wherein said reaction mixture has a composition in terms of mole ratios within the following ranges:YO.sub.2 /X.sub.2 O.sub.3 =15-35H.sub.2 O/YO.sub.2 =10-50OH.sup.- /YO.sub.2 =0.01-0.2M/YO.sub.2 =0.1-0.5R/YO.sub.2 =0.2-5.0and wherein the directing agent R is a non-cyclic amine having the formula (C.sub.2 H.sub.6 N).sub.n NH.sub.q wherein n is 2 or 3; q is 0 or 1 and n+q is 3;(b) maintaining the reaction mixture under crystallization conditions until crystals of said porous crystalline material are formed; and then(c) recovering said crystals from the reaction mixture.
