FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to a method for preparing oxirane. Method involves interaction of olefin and peroxide compound in the presence of catalyst and solvent in at least two in-line fitted reactors and each reactor comprises part of catalyst. Method is carried out for two successive epoxidation reactions with intermediate distillation. Method provides reducing formation of by-side substances.
EFFECT: improved preparing method.
