Abstract
Biodiesels were synthesised from five types of waste animal fats: veal and beef tallow, lard, chicken and goose fat, by means of chemical transesterification catalysed by alkali catalyst. Due to the fact that the presence of impurities negatively influences the quality of biodiesel, crude biodiesels were purified. Liquid-liquid extraction with previously prepared deep eutectic solvent choline-chloride/ethylene-glycol (molar ratio 1:2.5) was selected as the purification method. Experiments were performed at different mass ratio solvent/biodiesel in a laboratory scale batch extractor equipped with mechanical stirrer and optimal mass ratio was defined. Biodiesels were characterised and their properties were compared with the standard specification. Free glycerol from animal fats biodiesels was efficiently removed by the selected solvent.
