FIELD: organic chemistry.
SUBSTANCE: application: for power turbines exploited in gas-turbine engines (GTE) of aeronautical engineering, avia drives of gas-compressor units (GCU) and electric generators (EG). Oil contains in mass %: reaction products of N-phenylbenzolamine and 2,4,4 trimethylpentane 0,1-1,5, esters of trimethylolpropane and monobasic carboxylic acid or diisooctylsebacate 10-40, 2,6ditret-butylparacresol 0,5-5,0, tricresylphosphate 1-5, benzotriazol 0,001-0,5, polyalphaolefinic oil to 100. Technical result id improvement of thermal-oxidative stability of oil at 225°C and thermal stability at 250°C.
EFFECT: production of lubricating oil for power turbines with improved thermal-oxidative stability.
