Abstract
A gaseous mixture of HCN and Cl2 is ignited in the presence of H2 at at least 1200 DEG C. to form cyanogen which is subsequently recovered. Cl2, HCN and H2 in molar ratio 1:1.5-2.0:0.25-2.0 respectively, preheated if desired to 200 DEG C.-600 DEG C. are supplied either separately or variously premixed e.g. HCN and Cl2 may be premixed to a burner, where they p are ignited either by an oxy-hydrogen torch, an electric spark or a heated Pt wire, and burn at a temperature of at least 1200 DEG C. usually 1200-1800 DEG C. Combustion products containing cyanogen formed in a reaction time of 0.001-0.00001 seconds are removed from the burner and passed say through a water scrubber to remove acidic and other impurities, cyanogen being recovered as the resultant purified gas. The combustion may be carried out in the presence of an inert gas e.g. N2 or He and preheating of the separate gases or gaseous mixture is obtained either by heat exchange with the combustion products leaving the burner or by independent electrical heating.
