Analysis on Mechanism and Impact Factors of Transesterification for Biodiesel Production

The preparation and production technology of biodiesel was described in this paper. The synthetic effects such as water and free fatty acids in the raw material oil, temperature, pressure, catalyst, reaction time, alcohol-oil ratios, the mixing degree of raw materials and other aspects on the reaction were investigated. The transesterification mechanisms were discussed. The best synthetic technology conditions for synthesis of biodiesel by transesterification were obtained.
