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。
To produce micro-biodiesel from microbial oil, transesterification conditions were studied using oil from Rhodotorula glutinis 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 6 h. These conditions are favourable to accomplish the process of tansesterification sufficiently.
