摘要：The preparation and production technology of biodiesel was explained in this paper. The transesterification mechanism was discussed from the synthesis reaction of biodiesel. Then the synthetic effects on the reaction were investigated such as water of the raw material oil, free fatty acids, temperature, pressure, catalyst, reaction time, alcohol-oil ratios, the mixing degree of raw materials and other aspects. The best synthetic technology was obtained. As a clean renewable energy, biodiesel is mainly used as a substitute for fossil diesel fuel. Soaring oil prices and the environmental pressures promote the biodiesel industry's rapid development. Biodiesel production mainly uses the traditional batch transesterification technology. In this condition, a single set of devices can just reach the actual production of about 10,000 to 20,000 tons per year.Transesterification is the replacement of alcohol in glyceride by another alcohol. Such as methanol, ethanol, etc., methanol is the most common for the lower price, short carbon chain, polar, and can quickly react with the fatty acid ester, while alkaline catalyst can freely soluble in methanol. The oil used in transesterification is fed from a variety of natural oils and fats as well as food industry waste oil, which can be used as the raw materials to produce biodiesel. ?
