摘　　要：以精制棕榈油为原料,与无水乙醇进行酯交换反应制取生物柴油。探讨了反应物配比、催化剂用量、温度、反应时间等因素对产物产率的影响,采用正交实验优化合成条件确定了最佳合成条件及影响反应的关键因素,并运用气相色谱-质谱技术分析了产物的结构和组成,运用核磁共振技术对主要成分进行了结构确定。结果表明该生物柴油符合《柴油机燃料调和用生物柴油国家标准》(GB/T20828-2007),接近美国和德国的生物柴油标准,基本符合《轻柴油》(GB252-2000),适于中小规模及大规模生产应用。Bio-diesel was prepared from refined palm oil with anhydrous ethanol. The impact of reactant ratio, the amount of catalyst, temperature, reaction time and other factors on biodiesel synthesis were discussed. The best synthesis conditions of biodiesel production was optimized by Orthogonal experiments. The gas chromatography massspectrometric technique analysis of the product＇s structures and elements. Using NMR to determine ingredient structure. The result indicate that the bio-diesel accords with ＂Biodiesel blend stock （BD100） for diesel engine fuels＂ （GB/ T20828-2007） ,and the bio-diesel approaches to the level of the United States and Germany bio-diesel standard as well as the basic requirement of ＂Light diesel fuels＂ （GB252-2000）. It is suited for small,medium scale and large scale production application.
