摘　　要：本实验通过考察Ni、二元金属Cu-Si、SRNA-2型非晶态、Pd/C四种催化剂对大豆卵磷脂氢化的影响,筛选出Pd/C作为大豆卵磷脂氢化的催化剂。选择氢化条件为:温度60℃,催化剂添加量5%,压力1.5MPa,时间3h,获得了碘值为25.4gI2/100g的淡黄色氢化大豆卵磷脂。By investigating effects of several catalysts, Such as NiCu-S, SRNA-2 and Pd/C on soy lecithin hydrogenation, the catalyst Pd/C is selected for its excellent performance. Under the conditions of Pd/C among 5%, tenperature 60 ℃, H2 pressure 1.5 MPa, reaction time 3 h, the hydrogenation lecithin with iodine value 25.4 is obtained, and its color is light yellow.
