This review surveys chromatographic technology that has been applied to the characterization of biodiesel and its blends. Typically, biodiesel consists of fatty acid methyl esters produced by transesterification of plant or animal derived triacylglycerols. Primary attention is given to the determination of trace impurities in biodiesel, such as methanol, glycerol, mono-, di-, and triacylglycerols, and sterol glucosides. The determination of the fatty acid methyl esters, trace impurities in biodiesel, and the determination of the biodiesel content of commercial blends of biodiesel in conventional diesel are also addressed.
本综述探讨了已应用于生物柴油及其混合物表征的色谱技术。通常，生物柴油由植物或动物来源的三酰甘油经酯交换反应生成的脂肪酸甲酯组成。主要关注生物柴油中痕量杂质的测定，如甲醇、甘油、单酰甘油、二酰甘油、三酰甘油和甾醇糖苷。还涉及脂肪酸甲酯的测定、生物柴油中的痕量杂质以及传统柴油中生物柴油商业混合物的生物柴油含量测定。
