THE HISTORY OF DEVELOPMENT AND APPLYING OF ANTIOXIDANT ADDITIVES FOR FUEL AND OIL

The history of development and improvement of antioxidant additives develops and changes as the development of the engineering industry and in petrochemistry. This article describes the importance of additives for fuels and oils. The requirements for the quality of fuel have become much stricter, in connection with both environmental requirements and the requirements for the operation of the car. As a rule, new additives are developed because the technology is improved and developed and because of environmental standards become more stringent. The article presents the proposed mechanism of action of additives in the fuel. Today, there is a trend in the production of engines that operate at higher temperatures and it expects that the content of antioxidant additives will grow, and it will be use in the systems with higher temperatures. Analysis of world literature over the past 30 years has shown that in the process of creating effective additives for fuels and oils, the possibility of using numerous organic compounds for this purpose was a investigated. The possibility of using for this purpose numerous organic compounds was used. Without exaggeration, we can say that all classes of organic compounds containing various functional groups are used like additives. As an effective antioxidant additive for fuels and oils is phenol-type additives and alkylphenol isomers. It’s effect depends on the position of the alkyl radical in the benzene ring, significantly improve the performance, since the mechanism of action (radical-type antioxidants) is to transfer the free radical from the active peroxide molecule to the phenol molecule to form a low-active, highly shielded radical on the oxygen atom of phenol.
