Ionic liquid composition

Номер: CN116064182A
Автор: IRWIN MICHAEL D, CURTAS DOUGLAS R, HOLLINGSWORTH NICHOLAS, GRILL ALFRED, HARDACKER CHRISTOPHER
Принадлежит:

The present invention relates to an ionic liquid comprising (i) one or more nitrogen-free organic cations, each comprising a central atom or cyclic system having a cationic charge and a plurality of pendant hydrocarbyl substituents, and (ii) one or more halogen-free and boron-free organic anions, each comprising an aromatic ring bearing a carboxylate function and another heteroatom-containing function, the functional groups are conjugated to an aromatic ring and the conjugated system is anionic charged, and the aromatic ring additionally carries one or more hydrocarbyl substituents. The ionic liquid can be used as an additive to extend the service life of hydrocarbon liquids exposed to nitrogen dioxide contamination and provide friction and wear reduction.

Method for limiting chemical degradation caused by nitrogen dioxide contamination

Номер: CN116064183A
Автор: IRWIN MICHAEL D, CURTAS DOUGLAS R, HOLLINGSWORTH NICHOLAS, GRILL ALFRED, HARDACKER CHRISTOPHER
Принадлежит:

The present invention relates to a method for limiting the chemical degradation of a hydrocarbonaceous liquid in operation caused by liquid nitrification due to nitrogen dioxide contamination in operation at a bulk liquid temperature of 60 to 180 DEG C, comprising: preparing or obtaining a freshly prepared hydrocarbonaceous liquid; an ionic liquid comprising (i) organic cations each comprising a cationically charged central atom or cyclic system and a plurality of pendant hydrocarbyl substituents, and (ii) halogen-free and boron-free organic anions each comprising a cationically charged central atom or cyclic system and a plurality of pendant hydrocarbyl substituents, is added to the hydrocarbonaceous liquid prior to operation at bulk liquid temperatures. Each aromatic ring contains at least two heteroatom-containing substituent functional groups which are conjugated with the aromatic ring, and the conjugated system carries anionic charges; wherein the ionic liquid is added in an amount ...

Принадлежит:

The present invention relates to a method for limiting chemical degradation caused by nitrogen dioxide contamination. An additive composition for a hydrocarbonaceous liquid, the additive composition comprising an ionic liquid and a detergent additive, the ionic liquid consisting of (i) one or more organic cations, each comprising a cationically charged central atom or cyclic system and a plurality of pendant hydrocarbyl substituents, and (ii) one or more halogen-free, sulfur-free 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; and the detergent additive comprises, as an active ingredient, one or more neutral or overbased hydrocarbyl-substituted metal salts; the additive composition further optionally comprises a carrier liquid or a diluent.
