Abstract

An autocatalytic process for producing fatty acids from fatty acids methyl esters with an overall conversion higher than 90% which includes multiple hydrolysis reactions in series, in purely thermal conditions, with intermediate separation of phases after each hydrolysis reaction and before the subsequent, operating in excess of water, in order to separate the methanol/water phases from the equilibrium phase and favor the formation of fatty acids product.
