FIELD: chemistry. n SUBSTANCE: turbine oil contains the following in wt %: acid ester of alkenyl succinic acid 0.01-0.03, 2,6-di-tert-butyl-4-methylphenol 0.8-1.0, nitrogen-containing block-copolymer of ethylene and propylene oxides 0.01-0.07, alkyl toluene alkyl aminotriazole 0.01-0.05, 2,6-dialkylphenol-p-ethylalkylate 0.1-0.5, alkylthiophosphate ester 0.01-0.05, hydroxyl-containing copolymer of ethylene and propylene oxides 0.005-0.1, mixture of imidazolines based on plant organic acids and amines 0.01-0.10, petroleum oil with kinematic viscosity at 50°C of 20-23 mm 2 /s - 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 thermally treated at 30-90°C for 0.5-2 hours. n EFFECT: improved demulsifying and anticorrosion properties of the oil. n 3 tbl, 11 ex |
