【Abstract】 Pd/C catalysts were prepared by impregnation and used for the synthesis of 3, 4 - xylyl - D -ribitylamine. The influence of active carbons, reductive methods and different preparation methods on the catalytic activity was observed. The results showed that Pd/C was an efficient catalyst for the reductive condensation of D - ribose and 3,4 - xylidine, the yield could exceed 60% when the process was carried out under low pressures.更多还原
