Abstract
The invention involves a process for production of macrostructures of a microporous material. The process is characterized by the fact that seeds formed in or introduced by ion exchange or adsorption to a porous organic ion exchanger with the desired size, shape and porosity are made to grow and form a continuous structure by further deposition of inorganic material from a synthesis solution under hydrothermal conditions. The organic ion exchanger can be eliminated by chemical destruction or dissolution and, in so doing, leaves behind an inorganic microporous structure with the size and shape of the employed organic ion exchanger.
Claims28
A process of preparing composite material comprising a porous organic of inorganic ion exchanger material selected from the group consisting of crystalline molecular sieves and amorphous material, which process comprises:
- (a) forming a mixture comprising a synthesis composition capable of forming said microporous inorganic material and a porous organic ion exchanger;
- and
- (b) converting said synthesis mixture under hydrothermal conditions to form said inorganic material.
A composite material comprising a porous organic ion exchanger and a continuous three-dimensional network of inorganic material comprising a crystalline molecular sieve formed in the pore structure of said porous ion organic ion exchanger.
