The aim of the work was to determine the effect of oils quality and transesterification method on the degree of conversion of the fatty acids. Material consisted of 4 samples of oil: rapeseed oil obtained by the laboratory hot pressing of rape seeds oils in approx. 80 °C, waste rapeseed and palm oils and one refined rapeseed oil. Oils used in the one-stage transesterification were characterized by a lower hydrolysis and oxidation degree than the oils used in two-stage transesterification (double-base and base-acid method). The quality of the obtained crude methyl esters was determined in terms of acid number, peroxide value, the lipid composition by thin layer chromatography. Quantitative testing of the degree of transesterification and the share of individual esters of fatty acids was conducted by gas chromatography. Studies have shown that that degree of conversion of the fatty acid methyl esters is dependent on both the quality of the oil and the method of transesterification. If oils are characterized by a good quality, then a method of transesterification is less important. However, if oils are heavily contaminated, then the right technology for their transesterification should be chosen, e.g. oil with high content of FFA should be subjected to base-acid transesterification.
