FIELD: petrochemical industry; production of zeolite.
SUBSTANCE: the invention offers the method of production of titanium-containing zeolite by: (a) combining a capable to be hydrolyzed silicon compound and a capable to be hydrolyzed titanium compound; (b) adding a basic quaternary ammonium compound in a water medium into the mixture from a stage (a) and a hydrolysis of a reaction mixture at the temperature within the interval from 0 up to 100°C with production of a synthesis sol; and then (c) the synthesis sol aging at the temperature within the interval from 150 up to 190°C and (d) crystallizations of the synthesis sol at this temperature, differing by the fact, that aging duration at the increased temperature at the stage of (c) makes less than 240 minutes. The method ensures production of zeolite with a catalytic activity in reactions of epoxidation of olefins by hydrogen peroxide.
EFFECT: the invention ensures production of zeolite with a catalytic activity in reactions of epoxidation of olefins by hydrogen peroxide.
