FORMATION OF DISULPHUR MONOXIDE BY THE REACTION BETWEEN SULPHUR AND COPPER SULPHATE

Abstract

Sulphur reacts with anhydrous copper sulphate at 300-400° C in vacuum to give& sulphur monoxide, sulphur dioxide and cupric sulphide. The yield of disulphurmonoxide is dependent upon the particle size of copper sulphate employed and the temperature of the reaction. Experiments with labelled copper sulphate show that the sulphur in copper sulphate is always converted to sulphur dioxide. A mechanism is proposed for the reaction which will account for the experimental results.
