Sažetak
Fatty acid butyl ester (FABE) was synthetized from butanol and waste sunflower oil using base catalyst and conversions above 96 % were obtained. Synthetized FABE was mixed afterwards with mineral diesel in volumes up to 40 vol. % of FABE. Thermal behaviour of the mixtures was examined by thermogravimetic analysis (TG) and differential scanning calorimetry (DSC). The increase of temperature at 50 % mass loss and decrease in mass loss at 175 °C (maximum of diesel DTG curve) behaves linear (R2 > 0.99) with increase of FABE content in mixture indicating that TGA can be used for preliminary detection of FABE in diesel. DSC results show that all samples exhibit exothermal signals below -10 °C corresponding to crystallization of paraffins in diesel oil and partial crystallization of FABE. Maxima of exothermic crystallization peaks show small shift from - 14.3 °C (diesel) to -11.8 °C (40 vol. % FABE mixture).
