FIELD: chemistry.
SUBSTANCE: invention relates to the olefin epoxidation method, which includes the epoxidation of olefin with hydrogen peroxide in the presence of the catalyst which is a titanium silicate-based molecular sieve and a basic anion-exchange resin in olefin epoxidation conditions. The weight ratio of the catalyst and the basic anion-exchange resin is 1:0.05-1.5.
EFFECT: high conversion of hydrogen peroxide, selectivity for epoxidised olefin and longer service life of the catalyst.
