| Abstract: | Abstrct： This article studies the process conditions of the reaction taking place under catalyst condition. Optimum process conditions for preparing p-ehlorophenylhydrazine from p-ehloroaniline and hydrazine hydrate：the quality of p-ehloroaniline was 0.5mol, the molar ratio of p-chloroaniline and hydrazine hydrate and catalyst was 1 ： 2.5 ： 0.3, the volume of solvent was 90mL, reaction temperature was 110℃, reaction time was 5h. The yield of products reach to 92.2%. |
