摘　　要：利用乙二醇乙醚和精制大豆油合成出一种新型生物柴油——乙二醇乙醚豆油单酯。通过正交试验探讨最佳合成条件,对产物进行了红外光谱分析和氢核磁共振波谱分析,并利用单缸机研究柴油机的炭烟排放情况。结果表明,这种新型生物柴油的最佳合成条件为醇油摩尔比6∶1,催化剂用量0.5%,反应温度90℃,反应时间30 m in;燃烧新型生物柴油后,柴油机的炭烟排放水平大幅度降低。Ethylene glycol monoethyl ether soyate, a new kind of biodiesel has been synthesized using ethylene glycol monoethyl ether and refined soybean oil as reagents and Na as catalyst. Its chemical structure was characterized through FTIR and ^1H NMR analyses. Through orthogonal analysis of parameters in a four factor and three-level test, the optium condition obtained for the transesterification were： molar ratio of ethylene glycol ether to oil 6 ： 1, amount of Na 0. 5% of the oil weight, reaction temperature 90℃ ,reaction time 30 min. A single cylinder diesel engine was adopted to investigate engine smoke, and the engine smoke can he reduced significantly.
