Ozonolysis is used to oxidize a model cyclic molecule-decalin, achieving a conversion rate exceeding 50% with the main products being carboxylic acids. Through various spectroscopic methods, it is revealed that the key stage of the reaction involves the activation of the first C-H bond and the formation of peroxide radicals.
Ozonolysis is used for oxidation of a model cyclic molecule-decalin, which may be considered as an analog of saturated cyclic molecules present in heavy oil. The conversion of decalin exceeds 50% with the highest yield of formation of acids about 15-17%. Carboxylic acids, ketones/aldehydes, and alcohols are produced as intermediate products. The methods of UV-visible, transmission IR, attenuated total reflection IR-spectroscopy, NMR and mass-spectrometry were used to identify reaction products and unravel a possible reaction mechanism. The key stage of the process is undoubtedly the activation of the first C-H bond and the formation of peroxide radicals.
