| Abstract: | The rapid synthetic method of N, N＇-diphenylhydrazine with azobenzene through Zn-NH4X reduction system was reported. The effects of the molar ratio of drazobenzene to zinc powder and the amount of saturated solution of ammonium on yield were investigated. The optimum reaction conditions of Zn-NH4Cl were that the molar ratio of azobenzene to zinc powder was 1：5, the consumption of saturated ammonium chloride liquor was 1.5 mL, the reaction time was 12 min and the yield of N, N＇-diphenylhydrazine was 92.62%. |
