摘要：A process for the production of fatty acid esters comprising; (a) subjecting afatty acid or fatty acid mixture to esterification with a lower alkanol in an esterificationreactor maintained under esterification conditions to form a stream comprising thecorresponding lower alkyl ester or esters and recovering same; (b) recovering anoverhead stream from the esterification reactor comprising unreacted lower alkanol,water, and a heavy organic content comprising one or more of lower alkyl ester and/oracids; (c) subjecting the recovered overhead stream to distillation in a first distillationcolumn operating under first distillation conditions to separate a portion of the loweralkanol from a stream comprising the water, the remaining lower alkanol and the heavyorganic content; (d) recovering the stream comprising the water, the remaining loweralkanol and the heavy organic content; and (e) subjecting the stream comprising thewater, the remaining lower alkanol and the heavy organic content to distillation in asecond distillation column operating under second distillation conditions to provide anoverhead stream comprising lower alkanol and at least a major portion of the heavyorganic content and a water stream having a reduced heavy organic and alkanol content.
