    摘要: A novel process for producing mercaptophenols by the hydrogenolysis of polythiobisphenols in the presence of a nickel catalyst is disclosed. Raney nickel catalyst which is in advance poisoned with an organosulfur compound in which the sulfur atom has unshared electron pairs is especially effective as a catalyst. A process for producing polythiobisphenols which comprises: reacting a phenol having the general formula
    wherein each R independently represents a hydrogen, a halogen or an alkyl, with sulfur monochloride in a polar organic solvent in the presence of a nitrogen-containing organic compound as a catalyst which is selected from the group consisting of tertiary amines, quaternary ammoniums, alkylated acid amides and heteroaromatic compounds, in amounts of about 1-30 % by weight based on the amount of the phenol used. As a catalyst, bromine or an alkali metal halide is also usable.
