In this paper, the photochemical conversion process of aromatic hydrocarbons in Balakhani oil well (BO) as a case study was investigated. To study the composition of BO, first, it has been separated into the first, second, third, and fourth groups of aromatics using chromatography absorption column. It has been established that the composition of the separated groups is mainly composed of mono-, tri-, and tetracyclic aromatic hydrocarbons. It has been shown that the optical densities of the absorption bands corresponding to bi-, tri-, and polycyclic aromatic hydrocarbons decrease with increasing the photo-irradiation period, hence their maximum absorption band undergoes the hypsochromatic shift, which is characteristic for electron donor substances. It has been determined that the photochemical conversion process in the sample oil (BO) occurs with radical-chain and molecular mechanisms. As a result of the photochemical conversion process of arene-type aromatic hydrocarbons, the first difference during the photooxidation of endoperoxides, hydroxynones, quinones, and phenes is the formation of cyclic peroxides and quinones.

本文以Balakhani油井（BO）中芳烃的光化学转化过程为例进行了研究。为了研究BO的组成，首先，使用色谱吸收柱将BO分为第一，第二，第三和第四组芳烃。已经确定，分离的基团的组成主要由单，三和四环芳烃组成。已经表明，与双环，三环和多环芳烃相对应的吸收带的光密度随着光辐照时间的增加而降低，因此它们的最大吸收带经历了色移，这是电子给体物质的特征。 。已确定样品油（BO）中的光化学转化过程是通过自由基链和分子机理发生的。芳烃型芳烃的光化学转化过程的结果是，内过氧化物，羟壬酮，醌和苯酚的光氧化过程中的第一个区别是环状过氧化物和醌的形成。
