油脂替代品—蔗糖多油酸酯的合成(I)——超临界状态下合成油酸甲酯

Lipid Substitute-Synthesis of Sucrose Polyoleate(Olestra)(I) --Synthesis of Methyl Oleate in Supercritical CO_2 (SFR)

研究了以油酸与甲醇为原料 ,在超临界状态下合成油酸甲酯。对超临界合成油酸甲酯的反应条件进行了试验研究 ,并对合成产物进行了定性分析。超临界技术的应用 ,可以大大地缩短反应时间 ,降低了投料的甲醇 /油酸摩尔比 ,提高了酯化收率 ,简化了精制过程。

Methyl oleate is synthesized in supercritical CO 2 (SFR) with oleic acid and methanol We make a study on the reaction condition of supercritical synthesis and make a qualitative analysis on the product as well The application of the supercritical technique can greatly shorten the reaction time, decrease the methanol to oleic acid molar ratio, increase the esterification yield and simplify the refined process
