IMPROVED CATALYST FOR STERAMINE PRODUCTION. Methods are proposed for reducing the reaction time between an alkanolamine such as triethanolamine and an alkyl ester of a fatty acid, such as a triglyceride, a vegetable oil, a methyl ester, an ethyl ester etc., a fatty acid or a mixture their. The methods use a divalent zinc catalyst to facilitate and accelerate an esterification or transesterification reaction between alkanolamine and fatty acid, or alkyl fatty acid ester. |
