ABSTRACT:
A process for the preparation of a crystalline aluminosilicate of the pentasil type by hydrothermal crystallization of SiO.sub.2 and Al(OH).sub.3 in the presence of an alkali metal salt at from 80.degree. to 250.degree. C., wherein the crystallization is carried out in ether or aqueous ether. Particularly suitable solvents include the ethers from the group of the poly-(ethylene glycol) dimethyl ethers and mixtures of these ethers with water. The use of these crystalline aluminosilicates as catalysts for alkylating aromatics, and for preparing olefins and/or aromatics from methanol and/or dimethyl ether is also described.
