FIELD: chemistry.
SUBSTANCE: present invention relates to a lubricant composition for use in a turbine engine, the composition containing: (i) 50-99 wt % base oil; (ii) 0.01-5 wt % ionic liquid and (iii) 0.01-10 wt % additives, wherein the freezing point is lower than -54°C, the flash point is higher than 246°C, and kinematic viscosity at 100°C is in the range of 4.9 mm2/s to 5.4 mm2/s. The present invention also relates to use of the lubricant composition to lubricate a turbine engine and to use of an ionic liquid (version).
EFFECT: obtaining a lubricant composition suitable for use in turbine engine oil and for reducing formation of deposits in the lubricant composition.
