Abstract
A process for separating glycerin from methyl ester at an enhanced rate is disclosed. The improved process results from carrying out the transesterification reaction in a substantially non-polar and water free environment. A polymer selected from a group of polymers shown to be effective in such an environment is added to the product mixture which greatly improves the rate of separation between the methyl ester and the glycerin and reduces the number of required steps to accomplish the separation.
