FIELD: chemistry.

SUBSTANCE: invention can be used in turbine oil for lubricating gas, steam and water turbines, turbo-compressors, as hydraulic fluids in control systems of said assemblies. The composition of the turbine oil additive contains the following, wt %: acid ester of alkenyl succinic acid 1.04-1.57; nitrogen-containing block-copolymer of ethylene and propylene oxides 1.04-3.68; alkyl toluene alkyl aminotriazole 1.04-2.63; 2,6-dialkylphenol-p-ethylalkylate 10.42-26.32; alkylthiophosphate ester 1.04-2.63; mixture of imidazolines based on plant organic acids and amines 1.04-5.26; hydroxyl-containing copolymer of ethylene and propylene oxides 1.04-5.26; 2,6-di-tert-butyl-4-methylphenol - up to 100. The mixture of imidazolines based on plant organic acids and amines and the hydroxyl-containing copolymer of ethylene and propylene oxides is in form of a mixture which is first thermally treated at 30-90°C for 0.5-2 hours.

EFFECT: improved demulsifying and anticorrosion properties.
