| Abstract: | 3,5-diaminobenzotrifluoride was synthesized by using hydrazine hydrate as reducing agent in the presence of FeCl3.6H2O/AC used as H-transfer catalyst.The effect of the amount of hydrazine hydrate,the amount of catalyst and reaction time on the yields was investigated,and the structure of product was characterized by FTIR,1H NMR and DSC.When the 3,5-dinitrobenzotrifluoride was 11.8,g,80% hydrazine hydrate was 20 mL,the quantity of FeCl3.6H2O/AC was 0.06,g/2,g,dropping time was 60,min and reaction time was 30,min,the yield of 3,5-diaminobenzotrifluoride was reached to 83.1%. |
