Abstract
a ,a -Dichloropropionic acid is prepared by chlorinating a -chloropropionic acid at 160 DEG -180 DEG C., or chlorinating propionic acid at about 120 DEG C. to form a -chloropropionic acid and further chlorinating as above, in the presence of a compound RNHSO2X, where R is hydrogen or alkyl and X is hydroxy, alkoxy or a halogen. Specified catalysts are sulphamic acid, its acid chloride and its esters, e.g. H2NSO3CH3 and C2H5NHSO2Cl; these may be formed in situ, e.g. the last from ethylamine and sulphuryl chloride. Other organic additives which boil above a ,a -dichloropropionic acid and are soluble in the chlorination mixture may be present, e.g. aliphatic or aromatic sulphochlorides.
