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。

Abstract: 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.

Key words: soy lecithin, hydrogenation, catalyst
