TITANIUM-CONTAINING ZEOLITE, METHOD OF ITS PRODUCTION (Versions), METHOD OF EPOXIDATION OF OLEFINS AND DIQUATERNARY AMMONIUM COMPOUND FOR PRODUCTION OF TITANIUM-CONTAINING ZEOLITE Russian patent published in 1999 - IPC

FIELD: titanium-containing zeolite and methods of its production. SUBSTANCE: titanium-containing zeolite with structure isomorphic to structure of beta-zeolite containing atoms of silicate and titanium, and practically containing no atoms of aluminum in zeolite lattice, and having composition corresponding to general formula SiO₂:yTiO₂,, where y equals 0.01-0.25. Invention also includes description of method of production of titanium-containing zeolite (versions), method of epoxidation of olefins and diquaternary ammonium compound for production of titanium-containing zeolite. EFFECT: manufacture by simple methods (versions) of molecular sieves-catalysts selectively catalyzing of olefin epoxidation with the help of hydrogen peroxide. 24 cl, 3 dwg, 4 tbl
