Participants

Reaction Conditions

Reaction Steps

436 g of m-phenylmercapto thiophenol and 78 g of potassium hydroxide were dissolved in 500 ml of N-methyl-2-pyrrolidone, then 376 g of m-chlorophenyl phenylsulfide was added and the resultant mixture was heated to 170° C. After removing the water content, 20 g of cuprous chloride was added and heated to 210° C. and maintained at that temperature for 10 hours while stirring. After the reaction was over, the reaction product was treated by the same procedures as in Example Z-1 and bis(m-phenylmercaptophenyl)sulfide was obtained as a fraction at 255° C.-265° C./5 Torr by vacuum distillation. The product was referred as a comparative oil B and subjected to performance evaluation described above.
