METHOD OF PREPARING ALUMINUM ALCOHOLATES Russian patent published in 1999 - IPC

Abstract RU 2124518 C1

FIELD: inorganic materials technology. SUBSTANCE: invention relates to aluminum alcoholates used as catalysts in organic chemistry, waterproofing agents, etc. and also being of importance because of using their hydrolysis products to prepare pure aluminum oxide and complex systems on its basis. Invention utilizes natural activity of aluminum metal in its reaction with alcohols, which allows high-quality desired products to be obtained. Aluminum is activated with indium or indium-tin gallames by contacting aluminum surface with gallame resulting in diffusion of gallame components into aluminum bulk. In particular, reactions of aluminum with aliphatic and aromatic C2-C8-alcohols were performed giving rise to high (up to 98.5%) yields of desired products. EFFECT: increased yield of products and preserved environmental condition. 6 cl, 1 tbl, 10 ex
