Increasing and optimizing the quality indicators of motor oils, which are an indispensable part of modern engines, makes the study of synthesis methods and technologies of quality additives in this direction relevant. Alkylphenolate additives, as one of the main components of motor oils, serve to increase the quality blank indicators specified by the American Petroleum Institute (API) by being used in internal combustion engines.
The issue of long-term and reliable operation of machines and mechanisms is being addressed. The solution to the mentioned problems is complicated by the fact that, since modern cars move very quickly, engine parts are subjected to high technical stress, as a result of which existing motor oils fall short of the needs of the equipment.
Therefore, it is impossible to create a normal operating mode for modern technology without developing high-quality motor oils. To obtain such oils, it is important to develop high-quality additives.
In general, although a number of chemical substances have been studied as detergent-dispersant additives, the increase in the use of alkylphenol-based additives is due to their easy availability as raw materials, simple synthesis technology, and mainly multifunctionality.
As one of the leading enterprises in the industry, another important direction of the work is to make a special contribution to the largely limited literature in order to expand the scope of research on the current problem of motor oil additives.
The article is devoted to the synthesis and study of alkylphenolate additives. Alkylphenolate additives are divided into 3 groups: neutral (medium alkaline), basic and highly alkaline.
Highly alkaline alkylphenolates are more widely used than neutral and basic alkylphenolate additives due to their superior properties.
The purpose of this article is to show the various directions of methods for obtaining alkylphenolate additives found in the literature and, in particular, to summarize the research conducted at the Institute of Additive Chemistry named after Academician A.M. Kuliyev on methods for obtaining new highly alkaline alkylphenolate additives and improving the quality indicators of motor oils through their application.
