FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to a method for synthesis of alkylene oxides. Method involves contacting organic hydroperoxide and alkene with a heterogeneous epoxidation catalyst and removal of products flow containing alkylene oxide and alcohol. Fresh catalyst contacts with a feeding mixture taken in the mole ratio of alkene to organic hydroperoxide by at least 1.2-fold more as compared with their the mole ratio in the usual regimen of work. Invention allows enhancing the catalytic activity of catalyst and conversion of hydroperoxide.
EFFECT: improved method of synthesis.
