摘要
The transesterification of triglycerides under various conditions was considered in terms of the activation energy obtained from molecular orbital calculations. The transesterification reaction proceeds via a cyclic transition state, consisting of the carboxyl carbon and the alcohol. Moreover, the reaction pathway was shown by an activation energy analysis and an electrostatic potential distribution.
