【Abstract】 The synthetic method of reducing sulfanilamide via diazonium salt to p-sulfonamido phenylhydrazines is dealt with. The effect of the factors, such as the temperature of diazotizing reaction, the PH value of the reaction medium during the reduction of diazonium salt to p-sulfonamido phenylhydrazines and the amount of sodium suifite,on the reaction and production is discussed.更多还原
