Abstract:
A friction modifier for combustible fuels is provided that is prepared by combining a saturated carboxylic acid and an alkoxylated amine or etheramine. Furthermore, there also is an additive concentrate for use in fuels, especially in gasoline for internal combustion engines, comprising (a) a friction modifier comprising of a branched saturated carboxylic acid salt of an alkoxylated amine, such as isohexyloxypropylamine isostearate; (b) a detergent package, as well as the combustible fuels containing this additive concentrate. The particular selection of friction modifier (a) enables a stable additive concentrate to be formulated providing a significant benefit in friction loss when incorporated in gasoline used to fuel an internal combustion engine, and hence an improvement in fuel economy. Moreover, the use of the friction modifier (a) in combination with a detergent package permits increased fuel efficiency to be obtained without increasing the incidence of IVD deposits in combustion engines running on a fuel modified with the additive concentrate.
Abstract:
The present disclosure provides compositions and methods for reducing deposit formation in engines combusting a fuel containing ethanol and a corrosion inhibitor. The present disclosure also provides compositions and methods for reducing deposit formation in engines combusting a fuel containing ethanol, a corrosion inhibitor, and a dispersant.
Abstract:
The present disclosure provides compositions and methods for reducing deposit formation in engines combusting a fuel containing ethanol and a corrosion inhibitor. In particular, E85 fuels with a corrosion inhibitor are provided containing polyetheramine additives able to reduce, eliminate and/or prevent deposits on engine combustion surfaces and surfaces of engine components exposed to the fuel containing ethanol and a corrosion inhibitor
Abstract:
Disclosed are stabilized biodiesel fuel compositions, which compositions comprise a biodiesel fuel, for example the methyl esters of the fatty acids of rapeseed or soy oil, which compositions comprise a biodiesel fuel and an effective stabilizing amount of a combination of i) one or more compounds selected from the group consisting of the sterically hindered phenolic antioxidants and ii) one or more compounds selected from the group consisting of the triazole metal deactivators.
Abstract:
The invention relates to the field of masking mineral oil odor and the fragrancing of mineral oils. In this connection, the invention relates to a selection of particularly suitable odoriferous substances for masking a mineral oil odor and for fragrancing mineral oils. The invention furthermore relates to additives and to corresponding fragranced mineral oils themselves, in particular motor fuels and heating or lubricant oils.
Abstract:
A fuel lubricity additive is disclosed comprising an imidazoline. The fuel lubricity additive may be prepared by reacting an optionally substituted organic acid with an optionally substituted polyamine. Fuel compositions are also disclosed, comprising a fuel and the fuel lubricity additive. Processes for reducing wear in an engine, for example an internal combustion engine, using the fuel lubricity additive are disclosed.
Abstract:
The present invention relates to methods of improving the low temperature storage and performance properties of fatty acids and/or derivatives thereof, as well as compositions containing fatty acids and/or derivatives thereof having superior lower temperature storage and performance properties.
Abstract:
A lubricant composition is disclosed that comprises lubricating oil and a mixture of at least two antioxidants, the first antioxidant being a secondary diarylamine and the second antioxidant being a substituted para-phenylenediamine. Also disclosed is a method of increasing the oxidation stability of a lubricating oil comprising adding thereto at least two antioxidants, the first antioxidant being a secondary diarylamine and the second antioxidant being a substituted para-phenylenediamine.
Abstract:
Disclosed is a method of preparing terminally functionalized telechelic polymers using a cationic living polymer product or a terminal tert-chloride chain end of a carbocationic quasiliving polymer product, which comprises quenching the polymer product with an N-substituted pyrrole to thereby functionalize the N-substituted pyrrole at the terminal reactive polymer chain end(s). Also disclosed are the terminal functionalized polyisobuyl N-substituted pyrrole compounds where the polyisobutyl group is subsitituted at the 2 and 3 position of the N-substituted pyrrole.
Abstract:
This invention relates to a process for producing N-(methyl aryl)-2-lactams, N-alkyl-2-lactams, and N-(methyl cycloalkyl)-2-lactams by reductive amination of lactones with aryl or alkyl cyano compounds utilizing a metal catalyst, which is optionally supported.
