Benzophenone anil (7 g) is dissolved in benzene (50 ml) in a hydrogenation vessel and treated with dry hydrogen chloride, which precipitates the yellow hydrochloride. The hydrogen chloride is then replaced by hydrogen sulfide, and the vessel is shaken for 6 days under the pressure from a Kipps apparatus. The resulting deep blue solution is filtered under carbon dioxide from the precipitated aniline hydrochloride and unchanged benzophenone anil hydrochloride, the benzene is evaporated in a stream of carbon dioxide, and the residue is fractionated. Thiobenzophenone (3 g) distils at 176-178°/18 mm as a deep blue oil, which solidifies on cooling but remelts in the warmth of a hand. [Pg.658]
