The invention relates to a method for producing acyl peroxides. According to said method, an acyl compound is reacted with an organic hydroperoxide and a base, the pH of the two-phase mixture so obtained 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.

Continuous Method for Producing Acyl Peroxides
The invention relates to a continuous method for producing acyl peroxides. According to said method, an acyl chloride, carboxylic acid anhydride or chloroformate is reacted with an organic hydroperoxide or hydrogen peroxide in at least two mixed reaction zones that are connected in series, the acyl compound, the peroxy compound and an aqueous solution of a base being supplied to the first reaction zone. The first reaction zone comprises a cycle for the two-phase reaction mixture via a heat exchanger in which the reaction mixture is cooled. The method allows the reaction to be carried out reliably and with high space-time yields.
