摘要： Process for the production of esters of fatty acids and C1-C5 alkyl alcohols comprising the steps of: (a) providing a fatty feed comprising a triglyceride oil or fat, partial glycerides and/or free fatty acids, (b) neutralising said fatty feed by vacuum stripping at a temperature from 200° C. to 280° C., thus providing a vapour stream and a residue, (c) collecting a distillate by scrubbing said vapour stream, (d) transesterifying said residue with a C1-C5 alkyl alcohol while using an alkaline catalyst, (e) separating the transesterification reaction mixture from step (d) into a fraction comprising C1-C5 alkyl esters of fatty acids and an alcoholic fraction (a) wherein at least part of free acids obtained as side products in step (a) and/or (c) and/or (e) are esterifyed with an alcohol using an acid catalyst, the product of this esterification being added to said fatty feed or said residue.

摘要： This invention provides a process for forming fatty acid esters of C1-4 alkyl alcohols by alkaline transesterification of a glyceride oil, comprising the steps of: (a) providing a glyceride oil with a free fatty acid content below 2% more preferably below 0.5 weight % expressed as oleic acid; (b) mixing said glyceride oil with at least a part of one or more alcoholic phases originating from the alkaline transesterification as referred to above; (c) separating the mixture thus formed into a heavy, alcoholic phase and a light, pre-treated fatty phase; and (d) transesterifying said pre-treated fatty phase with said C1-4 alkyl alcohols. The transesterified product can be used in biodiesel production.
