Zusammenfassung:	Method for the dehalogenation of alpha-halogenated carboxylic acids by hydrogen in the presence of a group VIII precious metal-based catalyst and of sulphur or of compounds of sulphur; it also relates to a new catalyst based on a solid phase of sulphur and precious metal. The invention is particularly useful for the removal of dichloroacetic acid present in monochloroacetic acid.
