Annotation:

The authors of the article study anti-wear additives influence on the physical-chemical properties of synthetic oils. Esters are among the most promising bases for the production of oil for gas turbine engines, prove good stability at high temperatures, more environmentally friendly than petroleum oils and possess high oxidation resistance, which makes them an ideal choice for lubricating systems under high loads and temperatures. The authors of the article present the results of studying the physical-chemical properties of compound esters of trimethylolpropane alcohol and a mixture of synthetic carboxylic acids as well as pentaerythritol alcohol and a mixture of carboxylic acids. The results of compounding esters with domestically produced additives A-22, A-23, CD-7, K-36, K-33 in various concentrations are shown. Foreign analogues are compared with the obtained ester compositions.
