Peroxide oxidation of hydrocarbons is one of the most promising areas in green chemistry. This fact was emphasized at the COP29 summit held in Baku in November 2024. In the present study we considered the possibility of non-catalytic liquid-phase aerobic-peroxide oxidation of naphthenic hydrocarbons (decalin, adamantane) in order to obtain oxygen-containing compounds valuable for the national economy. The reaction was carried out in a barbotage flow reactor in the temperature range of 100-140⁰C. The most characteristic parameters of oxidation products - acid number and active oxygen content - in oxidate and condensate were determined. It is shown that under identical conditions the oxidation of decalin is more intensive than that of adamantane and, presumably, without destruction of the cyclic structure. It is found that deeper oxidation of decalin to acids is achieved at 130⁰C, and of adamantane, respectively, at 140⁰C. In spite of the fact that hydrogen peroxide is a hydroxylating agent, the influence of air oxygen as a co-oxidizer allows to bring the reaction to the stage of acids formation. The IR spectra of oxidation products clearly show the presence of carboxyl groups. The results of chromato-mass spectroscopic analysis of oxidate during oxidation of decalin and adamantane were obtained. It was found that aerobic-peroxidative oxidation of decalin and adamantane solution in decalin resulted in the formation of various classes of valuable oxygen-containing compounds, which can be purposefully used in the chemical industry.
