Abstract
A method is provided for the preparation of a synthetic, non-composited microporous membrane comprising a continuous array of crystalline molecular sieve material. A non-porous forming surface is contacted, under crystallization conditions, with a chemical mixture capable of forming the molecular sieve material. After a layer of the molecular sieve material is crystallized on the forming surface, the layer and the forming surface are recovered from the chemical mixture and the layer is separated from the forming surface.

A method for preparing a noncomposited, microporous membrane which comprises a continuous array of crystalline molecular sieve material the method comprising preparing a chemical mixture capable of forming the crystalline molecular sieve material, contacting a non-porous forming surface with the chemical mixture under crystallization conditions until crystallization of a continuous layer of crystalline molecular sieve material occurs on the non-porous forming surface, recovering the layer and the non-porous forming surface from the chemical mixture, rinsing the layer, and separating the layer from the forming surface to obtain said non-composited, microporous membrane.
