ABSTRACT:
A method is disclosed for preparing crystalline titanosilicate zeolite TS-1 from a reaction mixture containing only sufficient water to produce zeolite TS-1. In one embodiment, the reaction mixture is self-supporting and may be shaped if desired. In the method, the reaction mixture is heated at crystallization conditions and in the absence of an added external liquid phase, so that excess liquid need not be removed from the crystallized product.
