- A disulphide diisobutylcarbamoylmethyl thiuram method for the preparation of (by machine translation)
-
The invention discloses a method for the preparation of diisobutyl thiuram sulfide, its steps are: the two isobutyl amine into solvent, then dropping to the carbon disulfide, reaction after the dipping 0.5-1h, shall be diisobutylcarbamoylmethyl dithio Carbamic reaction liquid; the step (1) the diisobutylcarbamoylmethyl dithiocarbamate is slowly dripped into the reaction solution in a hydrogen peroxide solution, oxidizing reaction temperature rise after the dipping, filtering the reaction liquid after the reaction, the obtained precipitate washing, drying, be disulphide diisobutylcarbamoylmethyl thiuram disulfide. The preparation process of the invention is simple, by controlling the solvent, drop conditions, such as acceleration and dropping sequence, no longer add strong acid and strong alkali, reduce the production cost, reduces the potential safety hazard, less pollution, energy saving and environmental protection, the resulting product quality is good, high yield, the policy requirements of the green chemical States.
