Abstract
Peculiarities of high-temperature (150–170°C) oxidation of hexadecane as a model mineral lubricant are considered. Kinetic features of the oxidation process are presented, indicating a nonisothermal reaction mode, which can be caused by accumulation and decomposition of associated polyhydro-peroxides in the oxidizing system. The association of polyhydro-peroxides leads to formation of structures like reversed micelles, and evidence for their formation was obtained by the dye solubilization technique. The formation a microheterophase system at early stages of oxidation leads to reaction inhibition due to the formation of micellar aggregates in hydrocarbon oxidizing systems.
