摘　　要：以生物柴油副产物甘油为原料,用丙酮为溶剂分离得到丙酮不溶物(粗磷脂)。研究了液料比、提取分离温度、提取分离时间和搅拌速度对提取率的影响。用响应面法进行优化,最佳分离条件为:V(无水丙酮)∶m(甘油)为12∶1,提取分离温度16℃,提取分离时间13 min,搅拌速度372r/min。经验证实验,提取率达到98.9%。The phospholipids were purified by deoiling with acetone from the glycerol byproduct of producing biodiesel. The effects of ratio of solvent to material, extraction temperature ,time and agitating speed on the extraction rate were researched. The optimal extraction conditions were obtained by the response surface methodology as follows： ratio of acetone volume to glycerol mass 12：1 ,extraction temperature 16℃, extraction time 13 min, agitating speed 372 r/min. The extraction rate was 98.9% under the optimal conditions.
