Abstract
Provided are methods for decreasing the reaction time between an alkanolamine such as triethanolamine and a fatty acid alkyl ester such as, a triglyceride, a vegetable oil, a methyl ester, an ethyl ester, etc., a fatty acid, or a mixture thereof. The methods utilize a divalent zinc catalyst to facilitate and accelerate an esterification or transesterification reaction between the alkanolamine and the fatty acid, or fatty acid alkyl ester.
