Abstract
Cyanogen is produced by catalytic oxidation of HCN according to BE 764361 by oxidation with H2O2 in the presence of CuSO4 with or without ferric sulphate. The ferric sulphate may be prepared in situ by the reaction of H2O2 with ferrous sulphate. The Cu++ or Fe+++ ions may be recovered by precipitation with alkaline or alkaline-earth carbonates in the cyanogen-free reaction-soln. The cyanogen-free catalytic soln. may be recycled to the reaction step after the water introduced with the H2O2 has been distilled off.
