Abstract: An additive composition for limiting the chemical degradation of hydrocarbonaceous liquids due to nitrogen dioxide contamination at elevated temperature comprises the combination of an ionic liquid composed of a cation and a boron- and halogen-free, multi-functional anion and a detergent additive, the combination of ionic liquid and detergent serving to inhibit the nitration of hydrocarbonaceous liquid components that initiates degradation.
