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.
