(57) [Summary] [Constitution] Using thiol or thiol salt or disulfide including dithiocarbamic acid and its salt as a raw material, catalytically oxidizing with oxygen using a water-soluble copper chelate compound as a catalyst, and for vulcanization accelerators and other rubbers This is a method for producing dibenzozothiazolyl disulfide, benzothiazolylsulfenamide, and thiuram disulfide, which are useful as medicines. According to this production method, the vulcanization accelerator for rubber is It is obtained with high purity and high yield, and the production of by-products such as copper salts is suppressed. |
