ABSTRACT:
Sulfur produced by the reaction of hydrogen sulfide and sulfur dioxide in the presence of organic solvent solutions of alkali or alkaline earth metal salts of carboxylic acids is contaminated with these carbonaceous materials. The sulfur is purified by washing with water at elevated temperatures to reduce the carbonaceous material content to 0.007% carbon, by weight.
