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. The formation of diacyl peroxides and symmetrical halogenated diacyl peroxides as by-products is minimized by either technique.
