    摘要: A catalyst composition, particularly adapted for use in the production of dichloropropionic acid is provided. The catalyst composition comprises elemental iodine, which may be combined with a phosphorous trihalide or with bis (dimethyl thio carbamoyl) disulfide or with both. The catalyst composition makes possible the production of 2,2-dichloropropionic acid by direct chlorination of propionic acid, with substantially higher yields not heretofore obtainable in the production of 2,2dichloropropionic acid by direct chlorination of propionic acid.
