Abstract: A preparation, comprising a mixture of dibenzoyl peroxides where the mixture of dibenzoyl peroxides contains 50 to 99.7 mole % of a symmetric dibenzoyl peroxide and 0.3 to 50 mole % asymmetric dibenzoyl peroxides, shows a reduced decomposition temperature of the peroxides compared to the symmetric dibenzoyl peroxide and is suitable for hot cross-linking silicone rubber. The preparation can be produced by reacting a mixture containing a first benzoyl chloride and a second benzoyl chloride that is different therefrom with hydrogen peroxide, wherein the mixture of benzoyl chlorides contains 70 to 99.7 mole % of the first benzoyl chloride and 0.3 to 30 mole % of the second benzoyl chloride.

Abstract: 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.

Abstract: Composite material comprising—one or more heat-activatable free-radical initiators selected from the group consisting of organic peroxides and/or initiators having labile carbon-carbon bonds and particles which have a core-shell structure and the core of which comprises one or more magnetic materials, while the shell comprises silicon dioxide.

Abstract: A reactor which comprises a vessel (1) with a vessel bottom (2), a stirrer (3) arranged in the vessel, an emergency discharge valve (4) arranged in the vessel bottom for emptying the reactor in less than 600 seconds and at least one filtration device (5) arranged in the vessel bottom is suitable for the safe preparation of organic peroxides. The process for preparing an organic peroxide comprises the steps of preparing a solid hydroperoxide in the form of a suspension in the reactor, filtering the suspension through the filtration device (5) arranged in the vessel bottom (2) while retaining the solid hydroperoxide in the reactor and reacting the hydroperoxide with an alkylating agent, an acylating agent or a carbonyl compound.

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.
