Summary:Title screen
The proposed method of processing fuels derived from bio-raw materials allows for obtaining productsof organic synthesis. The simplified scheme of reactions occurring in the system of oxidizing biodieseland mathematic description were developed, and they are suitable for non-catalytic as well as Mocatalyzed oxidation of biodiesel by air oxygen. Kinetic regularities of the process of biodiesel aerobicoxidation were studied by using this kinetic model. It has been found out that Mo-catalyst acceleratesformation of all final products including epoxides by means of interaction with peroxyl radicals, i.e. thetraditional Sharpless epoxidation mechanism doesn’t match to this case. General parameters of theprocess, such as air supply speed and temperature do not impact on the character of componentsconcentration curves. Influence of the composition of FAME on the epoxidation selectivity was revealed.The growth of epoxide formation selectivity (up to 85% at 50% – conversion of C-C – double bonds)is observed when mono-/poly-unsaturated compounds ratio is increasing. Thus, fatty acid methylesters with different unsaturation degree demonstrate tendency to interact in various types ofreactions
