TITANIUM-CONTAINING ZEOLITE PRODUCTION METHOD Russian patent published in 2005 - IPC

Abstract RU 2256613 C2

FIELD: zeolite production processes.

SUBSTANCE: method comprises steps of preparing synthesis gel by combination and hydrolysis of silicon compound capable to be hydrolyzed, titanium compound capable to be hydrolyzed and basic quarternary ammonium compound in aqueous medium taken in quantities providing on conversion to said initial compound value of molar relation Si/Ti equal to or more than 30 and relation N/Si is in range 0.12 - 0.20; then crystallizing synthesis gel at temperature 150 - 220°C for time period less than 3 days.

EFFECT: possibility for producing titanium-containing zeolite with high catalytic activity at process of epoxydation of olefins with use of hydrogen peroxide.
