| titleOfInvention | PROCEDURE FOR THE SYNTHESIS OF 2- (ISOPROPILSULFINIL) -BENZOTIAZOLE |
| abstract | The present invention relates to a process for the synthesis of 2- (isopropylsulfinyl) -benzothiazole, which consists of reacting a 1: 1 to 1: 3 molar ratio of 2-mercaptabensothiazole to propylene, in a pressure vessel, in the presence of a catalytic amount of a monomeric or polymeric arenesulfonic acid, optionally in the presence of an inert organic solvent and where the reaction is conducted at 125-200 degrees C for a period of time sufficient to effect the formation of 2- (isopropylthio) - benzothiazole, and then react 2- (isopropylthio) -benzothiazole with 0-30 percent excess of aqueous sodium hypochlorite under high frequency mechanical homogenization conditions, at 10-40 degrees C, in the presence of NaHSO4 and urea , the amount of NaHSO4 or KHSO4 being sufficient to result in a final pH of the reaction mixture of 1.8-4-0, and the amount of urea being sufficient to suppress the formation of more than 5 per c 2- by weight of 2- (isopripylsulfonyl) -benzothiazole in the final product. |
