| Abstract: | The N2,N5-diphenyl-1,3,4-thiadiazole-2,5-diamine was prepared from hydrazine and Phenylisothiocyanate via Catalysis of acetic acid.The results show that when the molar ratio of hydrazine and Phenylisothiocyanate is 1∶1.3;reaction time 3.0 h;the yield of N2,N5-diphe nyl-1,3,4-thiadiazole-2,5diamine is 61.02 %.Its structure was confirmed by FT-IR,1HNMR and Mass spectra. |
