The aim of the study was to determine the ultrasounds treatment of frying oil on their properties important in order to biodiesel production. The research material was a frying oil, which prior to transesterification oil was treated with ultrasounds (37 kHz) during 15, 30 and 60 min. In next step, prepared samples were analysed in terms of fatty acid composition, acid value, FFA % and then subjected to alkali transesterification process. After producing methyl esters the yield of biodiesel was analysed with thin liquid chromatography technique (TLC), and then samples were characterized in terms of viscosity in 40 °C, density at 15 °C, acid value, sulphur content and flash point. The results showed that an ultrasonic treatment had a little impact on the fatty acid composition of the test samples. The yield of biodiesel was the higher the longer time of ultrasounds treatment were used. One the other hand, determined with thin liquid chromatography technique yield of biodiesel was the higher the longer time of ultrasounds treatment were used. What is more, the ultrasounds treatment of oil before transesterification process had no impact on viscosity, density and acid value of these samples, while flash point values and sulphur content were changed.
