Influence of the structure of higher paraffin hydrocarbons and their derivatives on the mechanism of high-temperature liquid-phase oxidation

The specifics of oxidation kinetics at 160A degrees C for structurally different hydrocarbons (normal and isobranched chains) and some of their functional derivatives were studied. A comparative analysis of products of the high-temperature oxidation of hydrocarbons was made and changes in the phase composition were studied using squalane and hexadecane as examples. It was shown that the spatial structure of a hydrocarbon subjected to oxidation makes a substantial contribution to the formation of reversed micelles. The kinetic behavior of squalane in oxidation and the solubilization of methyl orange by its oxidation products support the assumption that polyhydroperoxides form via the intramolecular 1,3-hydrogen abstraction mechanism.
