| Abstract: | The rapid synthetic method of hydrazobenzene with azobenzene through Zn-saturated solution of ammonium formate and Zn-saturated solution of ammonium benzoate reduction system was reported.The optimum reaction conditions of Zn-saturated solution of ammonium formate were that the molar ratio of azobenzene to zinc powder was 1∶3,the consumption of saturated ammonium formate liquor was 1.0 mL,the reaction time was 5min and the yield of hydrazobenzene was 87.5%.The optimum reaction conditions of Zn-saturated solution of ammonium benzoate were that the molar ratio of azobenzene to zinc powder was 1∶3,the consumption of saturated ammonium benzoate liquor was 2.0 mL,the reaction time was 3 min and the yield of hydrazobenzene was 86.4%. |
