Abstract

6031. Horsley, G. F., and United Alkali Co. March 10. Drawings to Specification. Monochloracetic acid is produced by chlorinating glacial acetic acid in the presence of a small percentage of sulphur, and acetyl chloride, the latter body acting as an accelerating-agent, and being automatically produced during the process, no addition thereof being necessary. In an apparatus for carrying out the process, the first vessel of a series is heated, and a small quantity of sulphur added to the acetic acid contained therein. On passing chlorine into the heated vessel, monochloracetic acid, and a small quantity of acetyl chloride are formed, the latter passing into the second vessel of the series, which is at ordinary temperature. On the completion of the reaction in the heated vessel, sulphur is added to the second vessel which contains glacial acetic acid and the acetyl chloride absorbed and which is now heated. The second vessel thus becomes the first of the series, and the originally heated vessel becomes the last, the monochloracetic acid being replaced by a further quantity of acetic acid. The reaction then continues as before. Instead of only one, a number of vessels may be simultaneously heated, the said vessels, when the reaction is complete, being cooled and becoming the last of the series. According to the Provisional Specification acetic anhydride may also be employed as an accelerating-agent.
