在合成脂肪酸的生产中使用的液体和固体石蜡常含有芳香烃等杂质。在文献中关于芳香烃对石蜡催化氧化过程的影响的文章很少。在氧化各种不同精制深度的液体石蜡时曾指出,随着石蜡中芳香烃含量的增加,在氧化产物中双官能团和多官能团的脂肪酸含量增加。包含在石蜡中的芳香烃主要是苯和萘的衍生物,石蜡中的芳香烃含量因原油产地不同和蜡的精制方法不同而异。
Liquid and solid paraffins used in the production of synthetic fatty acids often contain impurities such as aromatic hydrocarbons. There are few articles in the literature on the effects of aromatic hydrocarbons on the catalytic oxidation of paraffins. It has been pointed out at the time of oxidation of liquid paraffins of various refining depths that the content of difunctional and polyfunctional fatty acids in the oxidation products increases as the content of aromatics in the paraffin increases. The aromatic hydrocarbons contained in the paraffins are mainly benzene and naphthalene derivatives. The content of aromatics in the paraffins varies depending on the origin of the crude oil and the method of refining the wax.
