Abstract: The hydrogenation process of soybena PC-70 was optimized through single factor and orthogonal tests. The results showed that the optimal process conditions are as follows: using Pd/C as catalyst with the amount of 3.5 percent,H2 pressure in reactor 2 MPa,reaction temperature 65℃,reaction 70min,and stirring speed 180 r/min. The obtained product is yellowy with the iodine value of 40.38 gI2/100g.
