  • Preparation of unsymmetrical halogen-substituted diacyl peroxides
    Patent number: 3936506
    Abstract: Unsymmetrical halogen-substituted diacyl peroxides have been prepared either by rapidly adding an .alpha.-halogen-substituted aliphatic acyl halide and a hydrocarbon solvent to an aqueous solution of an alkali metal peroxide followed by portion-wise addition of an acyl halide or by rapidly adding an acyl halide and a hydrocarbon solvent to an aqueous solution of an alkali metal peroxide followed by portion-wise addition of an .alpha.-halogen-substituted aliphatic acyl halide.
