Process for the production of fatty acid esters of lower alcohols

摘要: The invention relates to a process for the production of fatty acid esters lower monovalent alcohols by transesterification glycerides in presence basic catalysts. according is characterized that carried out 0.025 0.045 mols an alkali or alkaline earth metal compound, preferably sodium hydroxide, potassium alcoholate, based on 100 g glyceride and subsequent purification effected addition 0.3 3.0 percent water hydration separation catalyst residues other impurities. In contrast known processes, it thus possible obtain any given high degree purity from untreated oils fats natural origin with contents up 20 acids free state at ambient temperature atmospheric pressure minor alcohol excess means simplest equipment.
