Abstract
A process for the esterification of a triglyceride. The process comprises forming a single phase solution of said triglyceride in an alcohol selected from methanol and ethanol, the ratio of alcohol to triglyceride being 15:1 to 35:1. The solution further comprises a co-solvent in an amount to effect formation the single phase and a base catalyst for the esterification reaction. After a period of time, ester is recovered from the solution. Esterification is rapid and proceeds essentially to completion. The esters may be used as biofuel or biodiesel.
Claims19
A process for the esterification of triglyceride, comprising forming a single phase solution of said triglyceride, an alcohol, a base catalyst for the esterification reaction and a cosolvent at a temperature that is less than the boiling point of the solution, said alcohol being selected from the group consisting of methanol and ethanol, and mixtures thereof, and the ratio of alcohol to triglyceride being in the range of 15:1 to 35:1, the cosolvent being in an amount sufficient to effect formation of the single phase;
- permitting esterification to occur in said solution and recovering ester from said solution.
