摘　　要：本文以葵花籽油为原料,采用甲醇进行改性,考察了改性反应条件对反应的影响.结果表明,葵花籽油改性(完全酯交换)的适宜条件为:葵花籽油与甲醇的物质的量比为1∶5,催化剂用量为0.5%(占葵花籽油质量的百分率),反应时间为3.5h,葵花籽油脂肪酸甲酯的产率达98.5%.采用气相色谱法及化学法对葵花籽油的成分和性质进行了分析,对酯交换产物进行了IR光谱分析.In this paper,a study on the modification of sunflower oil with methanol is presented. The optimal conditions of inter-esterification are as follows： the ratio of sunflower oil to methanol.. 1 ： 5,the amount of catalyst ：0. 5 %0 of sunflower oil quantity,the reaction time.3.5 hours,and the yield of product of sunflower oil methyl-fatty acids： 98. 5%. At the same time,the structures of the ester exchange products are identified by means of IR spectrum. The components and properties of sunflower oil are determined by means of chemical analysis and GC.
