摘要
利用尿素包合法对棉籽油中亚油酸进行纯化研究。通过正交试验确定其最佳提取条件,结果表明:尿素/甲醇为3∶1,脂肪酸/尿素用量为0.8∶1,包合时间为24 h,包合温度为-5℃,在此条件下亚油酸纯度达到90.7%。
Purifying methods of Linoleic Acid from cotton seed oil with urea adduction Fractionation were investigated in this paper.The results from orthogonal experiments indicated the optimum conditions,the results showed that are： the ratio of urea and ETOH is 3∶1,the ratio of fatty acid and urea is 0.8∶1,adduction time is 24 h,adduction temperature is-5 ℃,under these optimum conditions,the purity of linoleic acid is increased to 90.7 %.
