The combined soybean phospholipid fatliqour was prepared using soybean phospholipid as raw materials through four steps: hydroxylation, esterification with maleic anhydride, neutralization, sulphitation. The effects of some factors change in the hydroxylation and esterification with maleic anhydride to the reactions were researched emphatically. The optimum conditions of the hydroxylation reaction are obtaind:temperature is 65℃,time is 5h , the dosage of hydrogen peroxide and lactic acid are 20%and 4%respectively (based on the mass of phospholipid). The optimum conditions of the ester reaction are as follow:the dosage of catalyst is 0.8% (based on the mass of phospholipid), temperature of reaction is 100℃, time is 3h.
