PREPARATION METHOD OF DICYCLOHEXYL DISULFIDE

摘要

A preparation method of dicyclohexyl disulfide is provided in which sodium disulfide is reacted with chlorocyclohexane in an aqueous solvent to synthesize dicyclohexyl disulfide and in which at least a part of the reaction mixture containing by produced sodium chloride is acidified to be acidic and then neutralize it to recover sodium chloride. Furthermore a preparation method of sodium chloride is also provided in which at least a part of the reaction mixture containing sodium chloride synthesized by reacting sodium disulfide with chlorocyclohexane in an aqueous solvent is acidified to be acidic and then neutralize it to recover sodium chloride.
