Abstract
Abstract The present invention relates to a new zeolite material having a composition (molar ratios of the oxides) corresponding to the formula: M.sub.2/n O.Al.sub.2 O.sub.3.(20-150) SiO.sub.2 (M represents n-valent cation) to a process for the production thereof using hexamethylene imine and to the use of the zeolite material as a catalyst in the conversion of methanol and/or dimethyl ether to hydrocarbons.

Claim 3
Dependent Claim
75 words
A process for the production of a crystalline aluminosilicate according to claim 1, comprising mixing in water a silicic acid, an aluminum compound, alkali and hexamethylene imine in the range of oxidic molar ratios SiO 2 /Al 2 O 3 =10-200 OH - /SiO 2 =0.05-1.0 hexamethylene imine/Na 2 O=9.5-5.0, and reacting the reagents for from about 12 to 144 hours at a temperature of from 80° to 180° C., whereupon the aluminosilicate crystallizes out.
