The preferred thiolacid is thiolacetic acid, though thiolpropionic, thiolbutyric, thiolcaproic or thiolbenzoic acid may be used. The peroxy catalysts may be ascaridol, peracetic acid or perbenzoic acid. The process is preferably carried out in a non-reactive solvent such as dioxane, benzene, xylene, gasoline or other aromatic or aliphatic hydrocarbon at a temperature between 15 DEG C. and the boiling point of the solvent at atmospheric pressure. The product, which is soluble in dioxane and acetone, may be rendered insoluble by treatment with an alcoholic solution of sodium methylate followed by exposure to air.
