This paper discusses the use of esters of dicarboxylic acids as components of lubricants. Influence of molecular structure on the properties of ester compositions and the course of the esterification reaction. The theoretical foundations for the production of esters, the synthesis of the ester of caproic acid and butyldiglycol are considered, and the effect of temperature on the esterification process is reflected. Samples of a semi-synthetic oil were prepared, consisting of mineral oil and an ester of various concentrations. The viscosity and density were determined, the viscosity index of the samples under study was calculated. An oil with an optimal concentration of an ester and a high viscosity index was selected.
