Abstract
1339453 Cyanogen chloride DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT 4 June 1971 [6 June 1970] 18991/71 Heading C1A ClCN is prepared by reacting HCN and HCl in gaseous form or in aqueous solution, with H 2 O 2 in the presence of a cupric salt. The reaction mixture may also contain a ferric salt. Cupric chloride and ferric chloride are the preferred salts. The HCN may be in liquid or gaseous form or in aqueous solution such as the waste or spent acid formed in the production of acrylonitrile. The aqueous solutions of HCl may have a concentration from 3% to 36% (constant boiling acid); it may also be used in the form of an ironcontaining spent acid. The H 2 O 2 may be used as a 10 to 70% by weight aqueous solution. The reaction is preferably carried out at a temperature between 15‹ C. and 65‹ C.
