Production of fatty acids catalyzed by lipases not purified seed or plant fruit for subsequent esterification by acid catalysis

摘要

Production of fatty acids catalyzed by lipases not purified seed or plant fruit for subsequent esterification by acid catalysis. The present invention relates to the production of methyl or ethyl esters of fatty acid grease (biodiesel) in two steps: hydrolysis of a fatty acid material for the generation of greases and subsequent esterification of heterogeneous catalysis.In the process well. In question are not employed lipase purified from seeds, fruits or vegetables, to catalyze the production of acid through the hydrolysis of lipid material grease, which may or may not be present in the seed oils or.Fruit vegetable used as catalyst with lipase activity, and the subsequent esterification of carboxylic acids with alcohols of 1 to 2 carbon atoms using catalyst solid acidic sites.
