Title:
METHOD OF LIMITING CHEMICAL DEGRADATION DUE TO NITROGEN DIOXIDE CONTAMINATION
Document Type and Number:
Japanese Patent JP2023067819
Kind Code:
A
Abstract:
To provide an additive composition for limiting and a method of limiting chemical degradation of hydrocarbonaceous liquids due to nitrogen dioxide contamination in high-temperature operation.SOLUTION: An additive composition for hydrocarbonaceous liquids comprises an ionic liquid and a detergent additive. The ionic liquid comprises (i) one or more organic cations each comprising a central atom or ring system bearing a cationic charge and multiple pendant hydrocarbyl substituents, and (ii) one or more halogen-, sulfur- and boron-free organic anions each comprising one or more hydrocarbyl groups and one or more heteroatom-containing functional groups bearing a localized or delocalized anionic charge. The detergent additive comprises, as an active ingredient, one or more neutral or overbased hydrocarbyl-substituted metal salts. Optionally, the additive composition further comprises a carrier liquid or diluent.SELECTED DRAWING: None
