摘要
Cyanogen chloride is made by reacting HCN with hydrogen chloride or hydrochloric acid and H2O2 in aq. medium in the presence of cupric and ferric ions under pressure, and recovering cyanogen chloride on the one hand and O2 and N2 on the other, separately. The cupric ions are pref. present at 0.077 mole/l and the ferric ions at 0.0125-0.025-0.025 moles/l.
