Abstract
A method for producing an epoxide is disclosed. The method includes performing a reaction of an olefin compound and an oxidant by using a titanium-silicon molecular sieve as a catalyst, in the presence of a silicon oxide containing an alkaline earth metal as a coagent. The selectivity and yield of epoxide are increased by using a silicon oxide containing an alkaline metal as a coagent.
