摘要： 为了开发微生物油脂生产微生物柴油,以胶红酵母油脂为材料,以脂肪酸不饱和指数(UIFA)为指标,探讨了微生物油脂生成脂肪酸甲酯工艺的影响因素。结果表明:55℃、醇油物质的量之比(醇油比)40:1、催化剂硫酸用量为 75%、6h 以上的反应条件有利于甲酯化反应的充分进行。

Abstract: To produce micro-biodiesel from microbial oil, transesterification conditions were studied using oil from Rhodotorulaglutinis as raw material using unsaturation index of fatty acid (UIFA)as index. The result showed that the conditions of:reaction temperature 55℃, molar ratio of methanol to oil 40:1, H2SO4 75% based on oil weight, and time more than 6h. These conditions are favourable to accomplish the process of tansesterification sufficiently.

Key words: micro-biodiesel, transesterification, unsaturation index of fatty acid, Rhodotorula glutinis
