Reaction Mechanism and Impact Factors Analysis of Transesterification Biodiesel Production

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.
