NEW PROCESS TO MAKE MESOPOROUS CRYSTALLINE MATERIALS, AND MATERIALS MADE BY SUCH PROCESS

摘要

A novel process to make a mesoporous crystalline material comprises the steps of: (1) forming a layered composition that contains: (a) at least one complex of a polyol with suitable inorganic elements and (b) a surfactant; (2) simultaneously or sequentially: (a) hydrolyzing the complex in the layered composition and (b) dehydrating the hydrolysis product to form a cross-linked oxide of the suitable inorganic elements; and (3) calcining the product of Step (2) under conditions sufficient to produce an inorganic mesoporous crystalline material. The process can make both known mesoporous crystalline materials, and materials which conventional processes do not make.
