Abstract: The article presents an assessment of the influence of ozonation on the chemical composition of oil and petroleum products. Samples of crude light oil and distillate fractions with different boiling temperatures, composition and properties: kerosene, gasoil and fuel oil were used as objects of research. The main research methods are IR and 1H NMR spectroscopy. It is established that ozone treatment is more effective for crude light oils and medium-temperature oil fractions. Mainly polycyclic arenes, unsaturated compounds and alkyl substituents of the aromatic structures come in the reaction with ozone with the formation of new compounds with n - and cycloalkenyl hydrocarbon skeleton and monocyclic arenes. Ozonation of petroleum products contributes to the appearance of oxygen-containing compounds of different functionality in their composition: aldehydes, acids, linear and cyclic esters. The obtained regularities can be used to obtain heteropolar reagents based on petroleum products for the technology of flotation enrichment of coal.
