摘要：A new preparation of ethyl esters of fatty acids from vegetable or animal oilsand greases comprises :-a) transesterification of the oil, grease or glyceride mixture withexcess hydrated ethanol in the presence of an alkaline catalyst ; b) addition of a glycerinphase to the medium and evaporation of excess ethanol producing two phases, an esterphase and a non-miscible glycerin phase A : the excess ethanol is re-cycled to (A) ; c)separation of the glycerin phase A and the ester phases , which is purified to obtain therequires ethyl esters ; d) neutralisation of the phase A and separation of a (fatty acids +esters) phase and a glycerin phase which is dried ; e) glycerolysis of the (fatty acids +esters) phase with a fraction of the dried phase B in the presence of an alkaline catalyst,to form a mixture of glycerides and esters which are returned to the transesterificationstage (a).
