ABSTRACT:
A selective process for producing mercaptophenols is achieved by reducing the polysulfides which result from contacting phenols with sulfur chloride in a polar solvent reaction medium including a hydrogen chloride promoter, wherein the concentration of phenols is relatively dilute. The process selectivity promotes the sulfurization of phenols to polysulfides which are reducible to mercaptophenols.
