Abstract:
The invention relates to a method for producing tertiary amines based on polyisobutene polymers by reacting polyisobutene alcohol, optionally in admixture with polyisobutene aldehyde, with at least one secondary amine in the presence of at least one heterogeneous catalyst which has a nickel content, calculated as NiO, of less than 50% by weight. The invention also relates to a method for producing quaternized polyisobutene ammonium compounds from the tertiary polyisobutene amines obtained, using a quaternizing agent. The polyisobutene amines or quaternized polyisobutene ammonium compounds are used as fuel additives, in particular in diesel engines with common rail injection systems.
Abstract:
The use of betaine compounds of the formula R1-CO-NH-X-NR2R3)+- Y-COO- where R1denotes a linear or branched alkyl or alkenyl radical having 5 to 21 carbon atoms, R2 and R3 each independently denote C1- to C4-alkyl radicals, X denotes a hydrocarbon bridging element having 1 to 12 carbon atoms and Y denotes a linear or branched C1- to C4-alkylene group, as additives for fuels, especially as detergent additives for diesel fuels.
Abstract:
Procedimiento para la preparación de compuestos de nitrógeno cuaternizado, en el que a) a un compuesto de anhídrido de ácido policarboxílico se añade un compuesto que contiene al menos un grupo que tiene oxígeno o nitrógeno reactivos frente al anhídrido, y que adicionalmente contiene al menos un grupo amino cuaternizable, y b) el producto de la etapa a) cuaternizado; en donde al menos la etapa b) es realizada en ausencia de un solvente prótico y sin adición de un donador de H+, y en donde el agente de cuaternización es elegido de entre epóxidos.
Abstract:
The present invention relates to novel quaternized nitrogen compounds, to the preparation thereof and to the use thereof as a fuel and lubricant additive, more particularly as a detergent additive; to additive packages which comprise these compounds; and to fuels and lubricants thus additized. The present invention further relates to the use of these quaternized nitrogen compounds as a fuel additive for reducing or preventing deposits in the injection systems of direct-injection diesel engines, especially in common-rail injection systems, for reducing the fuel consumption of direct-injection diesel engines, especially of diesel engines with common-rail injection systems, and for minimizing power loss in direct-injection diesel engines, especially in diesel engines with common-rail injection systems.
Abstract:
The invention relates to novel quaternized nitrogen compounds, to the production thereof, and to the use thereof as fuel additives and lubricant additives, such as in particular detergent additives, additive packages that contain said compounds, and fuels and lubricants to which said additive packages have been added. The invention further relates to the use of said quaternized nitrogen compounds as a fuel addition for reducing or preventing deposits in the injection systems of direct-injection diesel engines, in particular in common-rail injection systems, for reducing the fuel consumption of direct-injection diesel engines, in particular diesel engines having common-rail injection systems, and for minimizing the power loss in direct-injection diesel engines, in particular in diesel engines having common-rail injection systems.
Abstract:
A lubricant comprising 2,5-(bishydroxymethyl) tetryhydrofuran dialkanoates This invention relates to a lubricant comprising a THF ester of the formula (I) as defined below. This invention further relates to a use of the THF ester as lubricant; and to a method for reducing friction between moving surfaces comprising the step of contacting the surfaces with the lubricant or with the THF ester.
