ABSTRACT:
The alpha-halogenated carboxylic acids/esters are dehalogenated by reaction with hydrogen in the presence of a catalytically effective amount of (i) a Group VIII precious metal catalyst and (ii) either sulfur or a sulfur compound, or (iii) a novel precious metal/sulfur solid phase catalyst; the subject dehalogenation is especially adapted for enriching the monochloroacetic acid content of MCAA/DCAA mixtures.
