ABSTRACT:
Method and apparatus for esterification of fatty acids or fatty acids contained in fats and oils with lower monovalent alcohol having 1 to 4 carbon atoms, comprising combining in a reaction section the fatty acids or fatty acids contained in fats and oils, and the alcohol to form a mixture, the combining forming enlarged interphases of the mixture by high or powerful dynamic shear forces and turbulence; at least one of strong mineral acid and acid ion exchange resin being present in the reaction section or a post-reaction section; starting esterification in the reaction section under pressure of 2 to 500 bar, and reducing pressure during the esterification so that a high interphase is maintained; and the esterification is carried out in the reaction section at a temperature of 50 to 300° C.
