Abstract (en)
[origin: EP1308498A1] Fatty acid lower alkyl ester production from undeacidified fats and oils comprises: esterifying triglyceride with lower alcohol in presence of Lewis acid and ester exchange of the deacidified mixture in presence of alkali hydroxide and lower alcohol and separating water and glycerol. <??>Fatty acid lower alkyl ester (I) production from undeacidified fats and oils comprises (a) esterifying technical triglyceride having acid number 1-50 with lower alcohol in presence of Lewis acid to reduce the acid number to less than 2; (b) ester exchange of the deacidified mixture in presence of alkali hydroxide and lower alcohol and separating water and glycerol; and optionally ( c) further ester exchange in presence of alkali alcoholate and separating glycerol.
