An efficient synthesis of thiobis(benzenethiol)

4,4'-Thiobis(benzenethiol) is prepared in a simple way by reduction of 4,4'-thiobis(benzenesulphonylchloride) by zinc granulate amalgam in the medium of sulphuric acid.

Preparation method of 4,4'-dimercaptodiphenylsulfide

The invention relates to a preparation method of 4,4'-dimercaptodiphenylsulfide. The method comprises the following steps: by using diphenylsulfide as an initial raw material, carrying out halogenating reaction to obtain 4,4'-dihalodiphenylsulfide, carrying out reaction on the 4,4'-dihalodiphenylsulfide and a vulcanizing reagent, and carrying out hydrolysis to obtain the 4,4'-dimercaptodiphenylsulfide. The method provided by the invention is simple to operate, has the advantages of higher product purity, high safety of the reaction process, and low cost, and is suitable for industrial production. More importantly, the method provided by the invention avoids using abundant strong acids in the conventional preparation method, and prevents the abundant wastewater generated in the production process from severely polluting the environment.
