摘　　要：研究了一种将不饱和油脂转化为一种碳数类似柴油的燃油的全新路径,其合成步骤主要是:首先将富含双键的油脂与甲醇酯交换得到脂肪酸甲酯;再将甲酯的双键氧化成羧酸并使其断裂;最后通过电解方法将其制备成一列碳数在10到18的烃类或酯类物质(燃料油)。此外还能得到丙酸、丙二酸、CO2、H2等高价值副产物。由于所得燃油碳数分布接近柴油,源于油脂,方法又不同于现有的三代生物柴油,故本文称其为第四代生物柴油。A new method of turning unsaturated fat into a kind of oil which is similar to diesel was studied. The steps are： Fatty acid methyl ester was obtained by oil with double bond exchanged with methanol ester; the double bond of methyl ester was oxidized to carboxylic acid and fragmented; then fuel oil was prepared by electrolytic process. In addition, byproduct of high value which was propionate, ma]onie acid, CO2, H2 were obtained. Because the carbon number was closed to diesel, and different from the third generation, so it is called fourth generation biodiesel.
