The catalysts were prepared by impregnation and precipitation method, and the active carbon,γ-Al2O3, silica and kieselguhr were selected as the carriers of catalyst. the effects of reaction conditions, such as reaction temperature, types of solvents, and types of hydrogen donors were investigated, It was found that the Pd/C catalyst was the best one, and its proper reaction conditions were also obtained as follow: sodium formate as hydrogen donor, water as solvent, reaction temperature of 70℃ and reaction time of 2.5h.
