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
