Method for producing epoxide

摘要

A method for producing an epoxide is provided. The method includes a step of performing a reaction of an olefine compound and an oxidant to form the epoxide by using a titanium-silicon molecular sieve as a catalyst, thereby increasing the conversion rate of the oxidant and the yield of the epoxide.

1. A method for producing an epoxide, comprising:
performing a reaction of an olefine compound and an oxidant in the presence of a solvent to form the epoxide by using a titanium-silicon molecular sieve of formula (I) as a catalyst:
(MxTiySi)Oz  (I) wherein M is one selected from the group consisting of Ca, Sr and Ba; x is in a range from 0.0005 to 0.03, y is in a range from 0.005 to 0.06, y increases as x increases, and z is x+2y+2, wherein the catalyst is prepared by preparing a mixture of a silicon source, a titanium source, a source of an alkaline earth metal, a template and water; stirring the mixture to obtain a mixed gel and removing alcohol in the mixed gel; mixing a dispersion with the mixed gel; performing a hydrothermal treatment on the mixed gel containing the dispersion; and sintering the mixed gel.
