ABSTRACT Aluminosilicates are produced by mixing sources of silica, alumina and alkali metal, water and one or more substituted secondary or tertiary amines or unsubstituted tertiary amines or the precursors of same and maintaing the mixture at a temperature in the range 80 to 210°C and a pressure in the range 70 to 400 psig for not less than 4 hours. In a preferred embodiment a di- and/or tri-alkanolamine is produced 'in situ' by reacting ethylene or propylene oxide with ammonia or a mono-alkanolamine. Aluminosilicates so-prepared can be used without modification as catalysts and catalyst supports. Catalytic activity can be enhanced by, for example, reducing the sodium content or impregnating with a compound of one or more metals belonging to Groups 1B, 11B, 111A, 1VA, VA and V111 or reaction with a compound of one or more non-metals of Groups 111A and VA of the Periodic Table.
