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 are analyzed at various feed rates of the gas phase. It was found that the oxidation process takes place 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 are determined. It was established that the selectivity of the epoxidation reaction decreases with the transition of the oxidation process from the diffusion region to the kinetic.

气泡反应器中脂肪酸甲酯的环氧化特征

摘要

在鼓泡塔反应器中，在气相的各种进料速率下，分析了葵花籽油脂肪酸甲酯与大气氧的混合物中亚油酸甲酯的环氧化模式。发现在扩散控制条件下，氧化过程发生在过渡区中。确定了扩散和动力学成分对脂肪酸甲酯氧化环氧化速率的贡献。已经确定，环氧化反应的选择性随着氧化过程从扩散区域到动力学的转变而降低。
