Abstract
The disclosure relates to a process for making catalytically active aluminosilicates from glasses by hydrothermal cristallization. The hydrothermal cristallization is more particularly effected in the presence of an aqueous solution of an inorganic alkali metal compound producing an alkaline reaction but in the absence of an amine. Useful alkali metal compounds comprise alkali metal carbonate, water glass, alkali metal hydroxide or alkali metal phosphate. The catalytically active aluminosilicates can be used for dehydrating alcohols, ethers and other oxygen-containing organic compounds with formation of hydrocarbons, or for isomerizing or alkylating hydrocarbons.
