Description

Die vorliegende Erfindung betrifft eine neue als Kraft- und Schmierstoffadditiv geeignete Mischung aus im wesentlichen

  • (A) mindestens einem Amin, welches einen Kohlenwasserstoffrest mit einem mittleren Molekulargewicht von 500 bis 10000 trägt,
  • (B) mindestens einem Kohlenwasserstoffpolymer mit einem mittleren Molekulargewicht von 300 bis 10000, welches in nicht hydrierter oder in hydrierter Form vorliegen kann, und
  • (c) mindestens einem üblichen Trägeröl.
The present invention relates to a new mixture of essentially suitable as a fuel and lubricant additive
  • (A) at least one amine which carries a hydrocarbon radical with an average molecular weight of 500 to 10,000,
  • (B) at least one hydrocarbon polymer with an average molecular weight of 300 to 10,000, which can be in non-hydrogenated or in hydrogenated form, and
  • (c) at least one common carrier oil.

Weiterhin betrifft die Erfindung die Verwendung der Mischung als Kraft- und Schmierstoffadditive sowie Kraftstoffe für Ottomotoren und Schmierstoffzusammensetzungen, welche die Mischung in wirksamen Mengen enthalten.The invention further relates to the use of the mixture as fuel and lubricant additives and fuels for gasoline engines and lubricant compositions which contain the mixture in effective amounts.

Vergaser- und Einlaßsystem von Ottomotoren, aber auch Einspritzsysteme für die Kraftstoffdosierung in Otto- und Dieselmotoren werden in zunehmendem Maße durch Verunreinigungen belastet, die durch Staubteilchen aus der Luft, unverbrannte Kohlenwasserstoffreste aus dem Brennraum und die in den Vergaser geleiteten Entlüftungsgase aus dem Kurbelwellengehäuse verursacht werden.Carburetor and intake systems of gasoline engines, but also injection systems for fuel metering in gasoline and diesel engines, are increasingly contaminated by contaminants caused by dust particles from the air, unburned hydrocarbon residues from the combustion chamber and the ventilation gases from the crankshaft housing that are conducted into the carburetor .

Die Rückstände adsorbieren Kraftstoff und verschieben das Luft-Kraftstoffverhältnis im Leerlauf und im unteren Teillastbereich, so daß das Gemisch fetter, die Verbrennung unvollständiger und wiederum die Anteile unverbrannter oder teilverbrannter Kohlenwasserstoffe im Abgas größer werden und der Benzinverbrauch steigt.The residues adsorb fuel and shift the air-fuel ratio at idle and in the lower part-load range, so that the mixture becomes richer, the combustion incomplete and in turn the proportions of unburned or partially burned hydrocarbons in the exhaust gas increase and the gasoline consumption increases.

Es ist bekannt, daß durch Zusatz von Detergentien das Einlaßsystem von Ottomotoren sauber gehalten werden kann (siehe z.B. M. Rosenbeck in Katalysatoren, Tenside, Mineralöladditive, Herausgeber J. Falbe, U. Hasserodt, S. 223 f., Thieme Verlag, Stuttgart 1978, und Ullmann's Encyclopedea of Industrial Chemistry, Vol. A 16, 719 ff, 1990, VCH Verlagsgesellschaft). Emissionen und Kraftstoffverbrauch werden dadurch reduziert und das Fahrverhalten verbessert. Das molekulare Bauprinzip solcher Detergentien kann allgemein beschrieben werden als Verknüpfung polarer Strukturen mit meist höhermolekularen lipophilen Resten. Vertreter hierfür sind z.B. Produkte auf Basis von Polyisobuten mit Amingruppierungen als polare Gruppen, wie in der EP-A 244 616 (1) beschrieben.It is known that the intake system of gasoline engines can be kept clean by adding detergents (see, for example, M. Rosenbeck in catalysts, surfactants, mineral oil additives, editor J. Falbe, U. Hasserodt, p. 223 f., Thieme Verlag, Stuttgart 1978 , and Ullmann's Encyclopedea of Industrial Chemistry, Vol. A 16, 719 ff, 1990, VCH publishing company). This reduces emissions and fuel consumption and improves driving behavior. The molecular construction principle of such detergents can be described in general as a linkage of polar structures with mostly higher molecular lipophilic residues. Representative for this are, for example, products based on polyisobutene with amine groups as polar groups, as described in EP-A 244 616 (1).

Die Schrift (1) lehrt weiterhin, daß in Kraftstoffadditiven bis zu ca. 50 Gew.-% der Wirksubstanz, also des Polyisobutylamins, ohne Verlust der Wirksamkeit durch Polyisobuten ersetzt werden können; solch ein Ersatz geschieht vornehmlich aus Kostengründen. Auf eine Verbesserung der Wirksamkeit bei bestimmten Polyisobuten-Mengen wird keinerlei Hinweis gegeben.The document (1) further teaches that in fuel additives up to about 50 wt .-% of the active substance, that is, the polyisobutylamine, can be replaced by polyisobutene without loss of effectiveness; such a replacement is primarily for cost reasons. There is no indication of an improvement in effectiveness with certain amounts of polyisobutene.

Eine weitere wichtige Additivkomponente für Kraftstoffe sind sogenannte Trägeröle. Bei diesen Trägerölen handelt es sich in der Regel um hochsiedende thermostabile Flüssigkeiten. Aus der EP-B 356 726 (2) sind Ester aromatischer Polycarbonsäuren mit langkettigen Alkoholen als Trägeröle bekannt. In der EP-A 374 461 (3) sind Kombinationen von Polyethern auf der Basis von Propylenoxid und/oder Butylenoxid mit einer Molmasse von mindestens 500 mit Estern aus Mono- oder Polycarbonsäuren und Alkanolen der Polyolen, wobei diese Ester eine Mindestviskosität von 2 mm²/s bei 100°C aufweisen, beschrieben, welche über synergistische Wirkungsmechanismen den Wirkungsgrad des Detergents erhöhen. Aus der US-A 5 006 130 (4) sind Mischungen von aliphatischen Alkylenpolyaminen mit mindestens einem öllöslichen synthetischen oder mineralischen Trägeröl bekannt.Another important additive component for fuels are so-called carrier oils. These carrier oils are usually high-boiling, thermostable liquids. EP-B 356 726 (2) discloses esters of aromatic polycarboxylic acids with long-chain alcohols as carrier oils. EP-A 374 461 (3) describes combinations of polyethers based on propylene oxide and / or butylene oxide with a molecular weight of at least 500 with esters of mono- or polycarboxylic acids and alkanols of the polyols, these esters having a minimum viscosity of 2 mm² / s at 100 ° C, described, which increase the efficiency of the detergent via synergistic mechanisms of action. US Pat. No. 5,006,130 (4) discloses mixtures of aliphatic alkylene polyamines with at least one oil-soluble synthetic or mineral carrier oil.

Die WO-A 91/03529 (5) lehrt die Kombination von Detergentien, die bestimmte Aminogruppen tragen, mit Polyetheralkoholen als Trägeröle. Diese Kombination trage insbesondere weniger als ihre Einzelkomponenten zum Anstieg des Octanzahlbedarfes (ORI, Octane Requirement Increase) bei, der durch Ablagerungen des Kraftstoffs oder der Additive an Motorteilen herrührt. Ein neuer Motor erreicht erst nach erheblicher Laufzeit seinen endgültigen Octanzahlbedarf, der dann erheblich höher liegen kann als zu Beginn. Allgemein sollten Additive diesen Effekt zumindest nicht verstärken.WO-A 91/03529 (5) teaches the combination of detergents which carry certain amino groups with polyether alcohols as carrier oils. This combination contributes less than its individual components to the increase in octane requirement (ORI, Octane Requirement Increase), which results from deposits of fuel or additives on engine parts. A new engine only reaches its final octane requirement after a considerable operating time, which can then be considerably higher than at the beginning. In general, additives should at least not increase this effect.

Die bekannten Additive des Standes der Technik zeigen noch nicht die optimale Reinigungswirkung im Motor, insbesondere die Verhinderung oder Reduzierung von Ventilablagerungen ist noch verbesserungsbedürftig.The known additives of the prior art do not yet show the optimal cleaning effect in the engine, in particular the prevention or reduction of valve deposits is still in need of improvement.

Aufgabe der vorliegenden Erfindung war es daher, Kraft- und Schmierstoffadditive mit verbesserter Wirksamkeit als Detergentien bereitzustellen.The object of the present invention was therefore to provide fuel and lubricant additives with improved effectiveness as detergents.

Demgemäß wurde die eingangs definierte Mischung gefunden, welche durch ein Gew.-Verhältnis der Komponente A zur Komponente B von 80:20 bis 60:40, insbesondere 77:23 bis 65:35, gekennzeichnet ist.Accordingly, the mixture defined at the outset was found, which is characterized by a weight ratio of component A to component B of 80:20 to 60:40, in particular 77:23 to 65:35.

Komponente AComponent A

Die Komponente A ist in Kraftstoffen primär als Detergens wirksam. Als Komponente A kommen solche Amine in Frage, die einen Kohlenwasserstoffrest mit einem mittleren Molekulargewicht von 500 bis 10000, vorzugsweise von 600 bis 2500 und besonders bevorzugt von 700 bis 1500 haben.Component A is primarily effective as a detergent in fuels. Suitable component A are those amines which have a hydrocarbon radical with an average molecular weight of 500 to 10,000, preferably from 600 to 2500 and particularly preferably from 700 to 1500.

Der Kohlenwasserstoffrest ist in der Regel verzweigt. Im allgemeinen handelt es sich um einen solchen Rest, der durch Polymerisation von Olefinen erhältlich ist. Vorzugsweise handelt es sich bei diesen Olefinen um C₂- bis C₆-Olefine, wie Ethylen, Propylen, 1-Buten, 1-Penten, besonders bevorzugt aber um Isobuten. Es kommen sowohl Homopolymere in Betracht wie auch Copolymere, z.B. Polymere aus 70 bis 100 Gew.-% Isobuten und 0 bis 30 Gew.-% 1-Buten. Bedingt durch ihren Herstellungsprozeß bestehen diese Polyolefine in der Regel aus einer Mischung von Verbindungen verschiedenen Molekulargewichts.The hydrocarbon residue is usually branched. In general, such a residue is obtainable by polymerizing olefins. These olefins are preferably C₂ to C₆ olefins, such as ethylene, propylene, 1-butene, 1-pentene, but particularly preferably isobutene. Both homopolymers and copolymers, e.g. Polymers made from 70 to 100 wt% isobutene and 0 to 30 wt% 1-butene. Due to their manufacturing process, these polyolefins generally consist of a mixture of compounds of different molecular weights.

In an sich bekannter Weise können diese Polyolefine nach Chlorierung mit Aminen umgesetzt werden. Bevorzugt wird aber eine Hydroformylierung des Polyolefins und Aminierung des so erhaltenen Aldehyd- und Alkoholgemisches unter hydrierenden Bedingungen, wie beispielsweise in (1) beschrieben, da dieser Weg zu chlorfreien Produkten führt. Die Amingruppe des Detergenses A leitet sich von an sich bekannten Aminen wie Ammoniak, primären Aminen wie Methylamin, Ethylamin, Butylamin, Hexylamin, Octylamin, sekundären Aminen wie Dimethylamin, Diethylamin, Dibutylamin, Dioctylamin oder Heterocyclen wie Piperazin, Pyrrolidin, Morpholin, die gegebenenfalls weitere inerte Substituenten tragen können, ab. Besonders bevorzugt ist Ammoniak.In a manner known per se, these polyolefins can be reacted with amines after chlorination. However, hydroformylation of the polyolefin and amination of the aldehyde and alcohol mixture thus obtained is preferred under hydrogenating conditions, as described, for example, in (1), since this route leads to chlorine-free products. The amine group of detergent A is derived from known amines such as ammonia, primary amines such as methylamine, ethylamine, butylamine, hexylamine, octylamine, secondary amines such as dimethylamine, diethylamine, dibutylamine, dioctylamine or heterocycles such as piperazine, pyrrolidine, morpholine, which may be further can carry inert substituents. Ammonia is particularly preferred.

Eine ganz besonders bevorzugte Ausführungsform für die Komponente A ist ein Polyisobutylamin mit einem mittleren Molekulargewicht von 700 bis 1500, wobei bis zu 20 Gew.-% der Isobuten-Einheiten durch 1-Buten-Einheiten ersetzt sein können.A very particularly preferred embodiment for component A is a polyisobutylamine with an average molecular weight of 700 to 1500, where up to 20% by weight of the isobutene units can be replaced by 1-butene units.

Komponente BComponent B

Als Kohlenwasserstoffpolymer B eignen sich insbesondere die als Vorstufe zur Komponente A beschriebenen Olefinpolymerisate. Solche Olefinpolymerisate weisen als Komponente B ein mittleres Molekulargewicht von vorzugsweise 400 bis 1750, insbesondere von 500 bis 1500 auf. Das Kohlenwasserstoffpolymer B kann noch herstellungsbedingt olefinische Doppelbindungen enthalten; solche Doppelbindungen können jedoch auch hydriert worden sein. Die Komponente B kann entweder separat zugegeben werden oder durch geeignete Reaktionsführung bei der Herstellung der Komponente A aus einem Überschuß der beschriebenen Olefinpolymerisate in das erfindungsgemäße Gemisch eingebracht werden.Particularly suitable as hydrocarbon polymer B are the olefin polymers described as precursors to component A. As component B, such olefin polymers have an average molecular weight of preferably 400 to 1750, in particular 500 to 1500. The hydrocarbon polymer B can still contain olefinic double bonds due to the production process; however, such double bonds can also have been hydrogenated. Component B can either be added separately or can be introduced into the mixture according to the invention by carrying out a suitable reaction in the preparation of component A from an excess of the olefin polymers described.

Eine ganz besonders bevorzugte Ausführungsform für die Komponente B ist ein Polyisobuten mit einem mittleren Molekulargewicht von 500 bis 1500, wobei bis zu 20 Gew.-% der Isobuten-Einheiten durch 1-Buten-Einheiten ersetzt sein können.A very particularly preferred embodiment for component B is a polyisobutene with an average molecular weight of 500 to 1500, where up to 20% by weight of the isobutene units can be replaced by 1-butene units.

Sowohl die Komponente A als auch die Komponente B können jeweils Mischungen verschiedener Einzelverbindungen sein.Both component A and component B can each be mixtures of different individual compounds.

Komponente CComponent C

Als Trägeröle C eignen sich im Prinzip alle üblicherweise für diesen Zweck verwendeten Verbindungen. Besonders bevorzugt werden jedoch Trägeröle C aus folgenden vier Gruppen:

  • (a) Mineralöle wie beispielsweise naphthenische oder paraffinische Mineralöle mit einer Viskosität von 2 bis 25 mm²/s bei 100°C;
  • (b) Polyether auf Basis von Propylenoxid und/oder Butylenoxid, insbesondere solche mit einer Molmasse von mindestens 500; insbesondere kommen hier Polyalkylenoxide in Betracht, die auf einem mittel- oder langkettigen Alkanol oder Alkandiol, einem von der Kettenlänge vergleichbaren Amin oder einem Alkylphenol, z.B. auf 1,6-Hexandiol, 1,8-Octandiol, iso-Tridecanol, iso-Nonylphenol, iso-Dedecylphenol oder iso-Tridecylamin, gestartet wurden. Pro Startermolekül können meist bis zu 50 mol, insbesondere 8 bis 30 mol, Propylenoxid oder Butylenoxid oder eine Mischung hieraus, welche blockartig oder zufällig verteilt eingebaut wird, umgesetzt werden;
  • (c) Polyetheramine auf der Basis von Propylenoxid und/oder Butylenoxid und Ammoniak oder primären oder sekundären Mono- oder Polyaminen, insbesondere solche mit einer Molmasse von mindestens 500; derartige Polyetheramine (c) werden vorzugsweise aus Polyethern (b) durch Aminierung nach bekannten Methoden hergestellt, wobei die endständige Hydroxylgruppe unter Wasserabspaltung durch eine Aminogruppe ersetzt wird;
  • (d) Ester aus Mono- oder Polycarbonsäuren mit Alkanolen oder Polyolen, insbesondere solche mit einer Mindestviskosität von 2 mm²/s bei 100°C; als Mono- oder Polycarbonsäuren können aliphatische oder vorzugsweise aromatische eingesetzt werden, als Esteralkohole bzw. -polyole eignen sich vor allem langkettige Vertreter mit beispielsweise 6 bis 24 C-Atomen; typische Vertreter der Ester (d) sind Adipate, Phthalate, iso-Phthalate, Terephthalate und Trimellitate des iso-Octanols, iso-Nonanols, iso-Decanols und des iso-Tridecanols.
In principle, all the compounds normally used for this purpose are suitable as carrier oils C. However, carrier oils C from the following four groups are particularly preferred:
  • (a) mineral oils such as naphthenic or paraffinic mineral oils with a viscosity of 2 to 25 mm² / s at 100 ° C;
  • (b) polyethers based on propylene oxide and / or butylene oxide, in particular those with a molecular weight of at least 500; polyalkylene oxides are particularly suitable here, which are based on a medium- or long-chain alkanol or alkanediol, an amine comparable in chain length or an alkylphenol, for example on 1,6-hexanediol, 1,8-octanediol, isotridecanol, isononylphenol, iso-dedecylphenol or iso-tridecylamine. Up to 50 mol, in particular 8 to 30 mol, of propylene oxide or butylene oxide or a mixture thereof, which is incorporated in blocks or randomly, can usually be reacted per starter molecule;
  • (c) polyetheramines based on propylene oxide and / or butylene oxide and ammonia or primary or secondary mono- or polyamines, in particular those with a molecular weight of at least 500; Such polyetheramines (c) are preferably prepared from polyethers (b) by amination by known methods, the terminal hydroxyl group being replaced by an amino group with elimination of water;
  • (d) esters of mono- or polycarboxylic acids with alkanols or polyols, especially those with a minimum viscosity of 2 mm² / s at 100 ° C; aliphatic or preferably aromatic mono- or polycarboxylic acids can be used; long-chain representatives with, for example, 6 to 24 carbon atoms are particularly suitable as ester alcohols or polyols; typical representatives of the esters (d) are adipates, phthalates, isophthalates, terephthalates and trimellitates of iso-octanol, iso-nonanol, iso-decanol and iso-tridecanol.

Weiterhin können als Trägeröle C jedoch auch Poly-α-olefine oder Polymere aus internen Olefinen, d.h. Olefinen mit nicht-terminalen Doppelbindungen, verwendet werden.Furthermore, carrier oils C can also be poly-α-olefins or polymers from internal olefins, i.e. Olefins with non-terminal double bonds can be used.

Generell können auch Mischungen aus den geannten Trägerölen, z.B. aus (a) und (b),(a) und (c), (a) und (d), (b) und (c) oder (c) und (d), eingesetzt werden.In general, mixtures of the aforementioned carrier oils, e.g. from (a) and (b), (a) and (c), (a) and (d), (b) and (c) or (c) and (d).

In einer besonders bevorzugten Ausführungsform setzt man als Komponente C ein Trägerölgemisch aus Polyethern (b) und Estern (d) ein, wobei (b) und (d) vorzugsweise im Gew.-Verhältnis 20:80 bis 80:20, insbesondere 35:65 bis 65:35, stehen.In a particularly preferred embodiment, a component oil mixture of polyethers (b) and esters (d) is used as component C, with (b) and (d) preferably in a weight ratio of 20:80 to 80:20, in particular 35:65 until 65:35.

Die Komponente C liegt in der erfindungsgemäßen Mischung üblicherweise in einem Gew.-Verhältnis zur Summe aus Amin A und Kohlenwasserstoffpolymer B von 5:95 bis 85:15, insbesondere 20:80 bis 70:30, vor.Component C is usually present in the mixture according to the invention in a ratio by weight to the sum of amine A and hydrocarbon polymer B of 5:95 to 85:15, in particular 20:80 to 70:30.

Die erfindungsgemäße Mischung kann weitere Komponenten D enthalten, wobei die Mengen an D 0 bis 40 Gew.-%, vorzugsweise 0 bis 10 Gew.-%, bezogen auf das Gesamtgewicht der Komponenten A bis C, betragen. Diese Komponenten D beeinflussen die Eigenschaften der erfindungsgemäßen Mischungen im Hinblick auf ihre Verwendung in Kraftstoffen nur in geringem Ausmaß.The mixture according to the invention can contain further components D, the amounts of D being 0 to 40% by weight, preferably 0 to 10% by weight, based on the total weight of components A to C. These components D only slightly influence the properties of the mixtures according to the invention with regard to their use in fuels.

Die Komponente D umfaßt an sich bekannte Additive für Mischungen, die Kraft- und Schmierstoffen zugesetzt werden. Darunter sind insbesondere Korrosionsinhibitoren, Demulgatoren, Detergentien oder Dispergatoren wie Amide und Imide des Polyisobutylbernsteinsäureanhydrids zu verstehen.Component D comprises additives known per se for mixtures which are added to fuels and lubricants. These include in particular corrosion inhibitors, demulsifiers, detergents or understand dispersants such as amides and imides of polyisobutyl succinic anhydride.

Gegenstand der vorliegenden Erfindung ist auch die Verwendung der beschriebenen Mischung aus den Komponenten A bis C als Kraft- und Schmierstoffadditive.The present invention also relates to the use of the mixture of components A to C described as fuel and lubricant additives.

Die vorliegende Erfindung betrifft weiterhin Kraftstoffe für Ottomotoren, welche wirksame Mengen der erfindungsgemäßen Mischung enthalten.The present invention further relates to fuels for gasoline engines which contain effective amounts of the mixture according to the invention.

Als Kraftstoffe kommen verbleites und unverbleites Normal- und Superbenzin in Betracht. Die Benzine können auch andere Komponenten als Kohlenwasserstoffe, z.B. Alkohole wie Methanol, Ethanol, tert.-Butanol sowie Ether wie Methyl-tert.-butylether, enthalten.Leaded and unleaded regular and premium gasoline can be used as fuels. The gasolines can also contain components other than hydrocarbons, e.g. Contain alcohols such as methanol, ethanol, tert-butanol and ethers such as methyl tert-butyl ether.

Die erfindungsgemäßen Kraftstoffe enthalten die Mischungen aus den Komponenten A bis C im allgemeinen in Mengen von jeweils 10 bis 5000 ppm, bezogen auf die Gesamtmasse, vorzugsweise 50 bis 1000 ppm. Die erfindungsgemäßen Kraftstoffe können neben den oben beschriebenen Komponenten D außerdem noch Antioxidantien, z.B. N,N'-Di-sec.-butyl-para-phenylendiamin, und Stabilisatoren, z.B. N,N'-Disalicyliden-1,2-diaminopropan, enthalten.The fuels according to the invention generally contain the mixtures of components A to C in amounts of 10 to 5000 ppm, based on the total mass, preferably 50 to 1000 ppm. In addition to the components D described above, the fuels according to the invention can also contain antioxidants, e.g. N, N'-di-sec-butyl-para-phenylenediamine, and stabilizers, e.g. N, N'-disalicylidene-1,2-diaminopropane.

Die Komponenten A bis C lassen sich zu klaren, homogenen Lösungen vermischen. Damit additivierte Kraftstoffe zeigen gegenüber den reinen Kraftstoffen deutlich geringere Ventilablagerungen. Weiterhin tragen die Additive nicht zu einem Anstieg des Octanzahlbedarfes (ORI) bei.Components A to C can be mixed to form clear, homogeneous solutions. Additive fuels show significantly lower valve deposits than pure fuels. Furthermore, the additives do not contribute to an increase in the octane requirement (ORI).

Die vorliegende Erfindung betrifft weiterhin Schmierstoffzusammensetzungen, welche wirksame Mengen der erfindungsgemäßen Mischung enthalten. Unter wirksamen Mengen sind hier in der Regel 0,1 bis 6 Gew.-%, insbesondere 0,5 bis 5 Gew.-%, bezogen auf das Gewicht der Schmierstoffzusammensetzung, zu verstehen.The present invention further relates to lubricant compositions which contain effective amounts of the mixture according to the invention. Effective amounts are generally understood to mean 0.1 to 6% by weight, in particular 0.5 to 5% by weight, based on the weight of the lubricant composition.
