In a process for producing a dicumyl peroxide comprising reacting a cumene hydroperoxide and an .alpha.,.alpha.-dimethylbenzyl alcohol in the presence of an acid catalyst, when a polar solvent exists in the reaction system, the cumene hydroperoxide of the starting material and the dicumyl peroxide of the resulting product are scarcely decomposed.

Process for producing dicumylperoxide

An aqueous emsulion of organic peroxide which is obtained by incorporating a water soluble alcohol of low molecular weight into a system which comprises an organic peroxide, an emulsifier and water, is good in the storage stability and it is capable of being transported at a low temperature.
