Abstract

Process for manufacturing oxirane by reaction of an olefin with a peroxide compound in the presence of a catalyst and a solvent in at least two reactors arranged in series, each of which contains a portion of the catalyst, according to which two epoxidation reactions are carried out in series including intermediate distillation, to minimize the formation of by-products.
