Abstract

The invention relates to a method for producing acyl peroxides. According to the method, an acyl compound is reacted with an organic hydroperoxide and a base, to generate a two-phase mixture. The pH of the two-phase mixture is adjusted to 6 to 13. The obtained organic phase is extracted with an aqueous solution of a base and the aqueous extract is recirculated to the reaction step. The method according to the invention allows the recirculation of unreacted hydroperoxide to the reaction step.
