Chlorination process

Abstract

Abstract Chloroacetyl chloride is obtained by the reaction between chlorine and a molar excess of ketene at 100-200 DEG C. Hydrochloric acid may be used with the chlorine, the ketene still being in large excess. Acetyl chloride is obtained in some quantity. In examples the reaction is described using varying quantities of reagents in accordance with the required proportions, preferably an excess of ketene of 50 per cent or more, and varying temperatures in the range, to give good yields of chloroacetyl chloride and acetyl chloride, with small quantities of dichloroacetyl chloride. A gaseous diluent may be added. The Provisional Specification describes a process in which the chlorine is used in excess.
