摘　　要：采用乳化结晶分离法对不同组成的脂肪酸的分离进行了研究。主要考察了结晶阶段乳化剂用量R、电解质用量W及稀释水用量RW 对分离结果的影响 ,以及适宜的R、W、RW 及其与组成的关系。研究结果表明 :R、W、RW 具有一适宜值 ,且它们随原料酸中饱和酸质量组成X不同而异。其中R、W分别与X成线性关系 ;RW 与X的关系亦有规律可寻。在适宜条件下进行脂肪酸分离 ,分离效果最好 (液酸产量最高 ,w(液酸 ) >90 % ) 。Using the improved hydrophilization process,fatty acid mixtures can be separated into one fraction rich in saturated fatty acid and the other rich in unsaturated fatty acids.The effects of surfactant ratio in crystallization step and quantities of magnesium sulfate and water of dilution on the result of separation were studied.The result showed that these factors had optimal values,which varied with mass fraction of saturated fatty acid.Relation between these factors and the mass fraction of saturated fatty acid was determined.
