Abstract
1338025 Cyanogen DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT 19 April 1971 [17 March 1970 21 March 1970 8 May 1970(2)] 23608/71 Heading C1A Cyanogen is produced by catalytic oxidation of HCN with H 2 O 2 in the presence of CuBr 2 , CuCl 2 , Cu(CN) 2 , Cu(NO 3 ) 2 , or CuSO 4 . Fe<SP>3+</SP> salts may also be present, with anions corresponding to the Cu salt (Fe 2 (SO 4 ) 3 may be formed in situ from FeSO 4 ). The HCN may be used as a gas, liquid or aqueous solution, and the H 2 O 2 as a 3-90% aqueous solution or as an organic solution. The temperature may be 0-100‹ C. and the pressure 1-5 atm. An organic solvent, e.g. tetramethylene sulphone, ethyl acetate or n-propyl acetate, may be present. The process may be operated continuously, the catalyst solution being distilled to remove water and recycled, any HCN and CN evolved during distillation also being recycled. Alternatively, the solution, optionally after distillation, may be treated with alkali metal or alkaline earth metal carbonate, e.g. CaCo 3 , to precipitate Cu and Fe carbonates which may then be converted, e.g. into sulphates with H 2 SO 4 , and recycled. CNCl is formed as by-product in Examples 6 and 7.
