FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to a method for preparing oxyrane. Method involves reaction of olefin with peroxide compound in the presence of catalyst and a solvent in at least two reactors arranged in series and each reactor contains part of catalyst. Peroxide compound is added to the first reactor only and the next or the following reactors are fed with peroxide compound presenting in medium preparing from the preceding reactor but not with fresh peroxide compound or used in this preceding reactor. Method provides enhancing output and reducing formation of by-side products.
EFFECT: improved method for preparing.
