| Abstract: | chlorobenzothiazole was synthesized with the recovery of 96.7% and purity of equal or more than 98% taking 2 mercaptobenzothiazole and sulfinyl chloride as the raw materials. The optimum conditions were as follows: temperature was 115℃; molar ratio of 2 mercaptobenzothiazole to sulfinyl chloride is 1∶1.05 and amount of catalyst, 0.8% of that of 2 mercaptobenzothiazole. |
