AMINE SALTS FOR USE IN GASOLINE ENGINES

Fuel compositions comprising at least 10 ppm by weight of a succinic ester acid amine salt or a succinamide acid amine salt (both "amine salt(s)"). The amine salt is the product of (a) and (b), wherein: (a) is an amine with (i) at least one tertiary nitrogen and (ii) at least one hydroxy a...

Zusammenfassung:Fuel compositions comprising at least 10 ppm by weight of a succinic ester acid amine salt or a succinamide acid amine salt (both "amine salt(s)"). The amine salt is the product of (a) and (b), wherein: (a) is an amine with (i) at least one tertiary nitrogen and (ii) at least one hydroxy alkyl functional group and/or at least one secondary amine functionality; and (b) is a hydrocarbyl-substituted succinic acid/or anhydride. The molar ratio of (a) to (b) may range from 3:1 to 1:3. The fuel composition may comprise gasoline, oxygenate, or mixtures thereof. Methods and uses for reducing carbonaceous deposits in an engine comprising operating the engine using the fuel composition having an amine salt therein.
