Abstract
A halogenated hydrocarbon such as a halogenated ethane or propane is dehalogenated by subjecting to electrolysis an aqueous reaction system containing the halogenated hydrocarbon, a halide of metal having dehalogenating ability and a detergent. The detached halogen leaves the reaction system in elemental form.

A method of dehalogenating a halogenated hydrocarbon with liberation of the detached halogen in elemental form, the method comprising the step of subjecting to electrolysis a reaction system containing water, a halogenated hydrocarbon to be dehalogenated, said halogenated hydrocarbon in said reaction system is a halogenated alkane having at least two but not more than three carbon atoms and at least two atoms of at least one halogen selected from the group consisting of fluorine, chlorine and bromine;
- with the proviso that the halogens to be removed are on different carbon atoms, zinc chloride and a detergent.
A method of dechlorinating halogenated alkanes having two or three carbon atoms and at least two chlorine atoms with the two chlorine atoms on different carbon atoms with liberation of the detached chlorine in elemental form, the method comprising the step of subjecting to electrolysis a reaction system containing water, at least one of said halogenated alkanes, zinc chloride and a detergent.
