実験手順
A mixture of 3.3 g of 2-mercaptobenzothiazole and 10.0 g of ethyl p-toluenesulfonate was heated to 150° C. to react them for 6 hours. The reaction product was cooled to 80° C. and then 30 ml of ethanol was added to it, thereby producing an ethanol solution of 2-ethylmercapto-3-ethylbenzothiazolium p-toluenesulfonate.
