Abstract

The patterns of epoxidation of linoleic acid methyl ester in a mixture of methyl esters of sunflower oil fatty acids with atmospheric oxygen in a bubble column reactor were studied at various feed rates of the gas phase. The results showed that the oxidation process occurred in the transition region, under diffusion control conditions. The contributions of the diffusion and kinetic components to the rate of oxidative epoxidation of fatty acid methyl esters were demonstrated. The selectivity of the epoxidation reaction decreased with the transition of the oxidation process from the diffusion region to the kinetic.
