Abstract
A process for decomposing ammonium thiocyanate and equivalent compounds comprising mixing the compounds with molten ammonium sulfate at atmospheric pressure and about 310.degree. C. The compounds decompose giving off carbon dioxide, sulfur dioxide, ammonia and sulfur and leave a residue of ammonia salts but no organic materials.
Claims7
A process for decomposing a compound selected from the group consisting of ammonium thiocyanate, thiourea or mixtures thereof comprising maintaining a quantity of ammonium sulfamate in a molten state, adding a less than molar equivalent of the compound to said ammonium sulfamate and maintaining the resulting mixture at atmospheric pressure and a temperature greater than 250.degree. C. but less than 444.6.degree. C. until completion of the reaction.
