The process of separating urea and fatty acids form urea inclusion compounds was studied.
采用尿素包合法对蚕蛹油中的多不饱和脂肪酸进行富集，为了合理利用资源，实现尿素和脂肪酸的高效回收利用，研究了蚕蛹油尿素包合物中尿素和脂肪酸的分离回收工艺。
A simple isolation and purification method for arachidonic acid (5, 8, 11, 14-eicosatetraenoic acid, AA) from microbial lipids is presented. At first, AA was concentrated by urea inclusion reaction from mixed fatty acids made from microbial lipids, and then esterified with BF3-methanol.
为满足花生四烯酸样品制备的需要，将微生物油脂中制得的脂肪酸先经尿素包合和甲酯化后，再利用反相高效液相色谱法分离纯化其中的花生四烯酸。
The results showed that 97.55% of total recovery rate of urea and fatty acids was obtained when the urea inclusion compounds were dissolved in water at 70℃ with 2:1 solid-liquid ratio, then extracted with petroleum ether to recover fatty acids, the residual liquid was crystallized for 2 h at 0℃.
结果表明最佳工艺条件为：水作溶解尿素包合物的溶剂，在70℃固液比为2：1（pH为2~3）的条件下全部溶解，用石油醚革取出脂肪酸，剩余的尿素溶液在0℃下结晶2h。
