Immobilized lipase Lipozyme TL IM-catalyzed transesterification of soybean phosphatidylcholine(PC,90%) with linoleic acid(LA,95%) was carried out in toluene.The six major factors of phosphatidylcholine concentration(toluene as a solvent),substrate ratio(molar ratio of LA to PC),lipase dosage(based on the mass of substrates),water addition(based on the mass of lipase),reaction time and reaction temperature were discussed.The optimum reaction conditions were as follows: PC concentration 0.25 g/mL,molar ratio ... |
