| titleOfInvention | Method for the production of fatty acid esters from non-deacidified fats and oils |
| abstract | (a) technische Triglyceride mit Säurezahlen im Bereich von 1 bis 50 in Gegenwart von Lewis-Säurennmit niederen Alkoholen verestert und dabei die Säurezahl auf Werte unterhalb von 2 absenkt, (b) die auf diese Weise erhaltene entsäuerte Mischung in Gegenwart von Alkalihydroxiden und niederennAlkoholen einer Umesterung unterwirft und dabei Wasser sowie freigesetztes Glycerin abtrennt,nund gegebenenfalls (c) das auf diese Weise erhaltene Umesterungsgemisch in Gegenwart von Alkalialkoholaten einernweiteren Umesterung unterwirft und dabei ebenfalls freigesetztes Glycerin abtrennt. A process is proposed for producing fatty acid lower alkyl esters from non-deacidified fats and oils, in which (a) esterifying technical triglycerides with acid numbers in the range from 1 to 50 in the presence of Lewis acids with lower alcohols and thereby reducing the acid number to values below 2, (b) the deacidified mixture obtained in this way is subjected to a transesterification in the presence of alkali metal hydroxides and lower alcohols, thereby separating water and released glycerol, and if appropriate (c) subjecting the transesterification mixture obtained in this way to a further transesterification in the presence of alkali alcoholates and likewise separating released glycerol. |
