FIELD: chemical technology.
SUBSTANCE: invention relates to the improved method for re-esterification of fat and/or oil of biological origin by alcoholysis. Method involves preparing fat and/or oil of biological origin for re-esterification process in suitable capacity followed by alcoholysis by addition of monoatomic alcanol and catalyst to the prepared fat and/or oil. Amino acid or derivative of amino acid metallic salt insoluble in monoatomic alcanols is used as a catalyst. Also, invention relates to fatty acid monoesters preparing by indicated method that are used as diesel fuel. This simple method provides preparing the end product with high yield that is not contaminated with catalytic material impurities.
EFFECT: improved method for re-esterification.
