Sažetak
The goal of this work was to synthesize biodiesel from various feedstocks and to extract glycerol and glycerides from produced biodiesel samples with choline chloride based deep eutectic solvent. Biodiesel samples were synthesized via base-catalysed transesterification with methanol. Batch extraction experiments were conducted with choline chloride – ethylene glycol (molar ratio 1:2.5) deep eutectic solvent at room conditions (for oils) and at an elevated temperature (60 °C, for fats that were not liquid at room conditions). Biodiesel prepared from the mixture of palm and sunflower oil was also purified continuously, in a Karr column with the same solvent. Glycerol and glycerides concentrations were determined using gas chromatography and samples were characterised using Fourier transformation infrared spectroscopy and proton nuclear magnetic resonance spectroscopy. Choline chloride based solvent proved to be efficient for purification of biodiesels, especially for free glycerol. The greatest efficiency was achieved for the samples with the highest concentrations of glycerol and glycerides due to the higher driving force. The highest quality biodiesel was produced from fresh and waste sunflower oil and deacidified waste animal fat.
