| Summary: | This paper studies the processes of radiation-induced polymerization and post-polymerization in motor fuels. It is important that the fuel components remain stable at high temperatures and radiation under operating conditions. When organic substances are exposed to ionizing radiation, complex chemical changes occur. Therefore, in addition to knowing the usual physicochemical properties of organic fuels and lubricants, it is also important to understand how they behave under the influence of radiation - this is called their radiation resistance. Adding small amounts of aromatic compounds to the fuel can increase its resistance to gamma radiation. The study of this issue is of practical importance. The purpose of this work is to study how the physicochemical properties of gasoline change when small amounts of benzene are added under the influence of ionizing radiation from 60 oC. However, post-polymerization processes in gasoline have not been studied in detail. The processes caused by radiolysis can continue for a long time after the cessation of exposure to radiation, which changes the composition of the fuel. As a result, the performance characteristics of the fuel deteriorate. To study these post- polymerization processes, irradiated samples of pure gasoline and gasoline with various benzene additives were tested immediately after irradiation and again after 2, 4 and 8 months. This study was conducted due to the importance of the problem and the lack of information on it. The kinetics of post-polymerization processes during 8 months after irradiation show that the rate of the process and its contribution to the overall polymerization depend on the irradiation time, the density of the initial mixture and the dose. |
