| Abstract: | Pd/C catalysts were prepared by impregnation method and used in dehydrogenation of 1,2,3,4-tetrahydrocarbazole to carbazole.The preparation condition such as pH value,serosity volume and reaction time were optimized by response surface methodology.The optimum condition was attained as follows：pH value 7.86,serosity volume 139.76 mL and reaction time 75.70 min.The yield of carbazole was close to 100% under the optimum condition. |
