Complex esters of 2.5,5.5-tetrametylolcyclopethane with heptanedioic and hexanoic acids, as well as methyl and 2-ethylhexyl alcohols have been synthesized and studied. Few compositions have been obtained adding these esters to the industrial ones of 5-20 % diisooktyl sebacylic. It was defined that exploitation characteristics of these compositions are significantly higher than those of DOS: viscosity index, flash point, thermal oxidative stability and lubricating characteristics. Based on these parameters, it is recommended to use in the future these compositions in the preparation of aircraft oils of gas-turbine engines instead of DOS esters.
