- the present invention relates to new uses of corrosion inhibitors in fuels.
- Corrosion inhibitors are common additives in fuels and lubricants, often based on acid group-containing structures, e.g. Dimer fatty acids.
- a disadvantage of these corrosion inhibitors is that they tend to precipitate, especially in the presence of calcium ions, thereby reducing their corrosion-inhibiting effect.

Description
Die vorliegende Erfindung betrifft neue Verwendungen von Korrosionsinhibitoren in Kraftstoffen.The present invention relates to new uses of corrosion inhibitors in fuels.
Korrosionsinhibitoren sind gängige Additive in Kraft- und Schmierstoffen, die oftmals auf säuregruppenhaltigen Strukturen beruhen, z.B. Dimerfettsäuren.Corrosion inhibitors are common additives in fuels and lubricants, often based on acid group-containing structures, e.g. Dimer fatty acids.
Nachteilig an diesen Korrosionsinhibitoren ist, daß sie insbesondere in Gegenwart von Calcium-Ionen zu Ausfällungen neigen und dadurch ihre korrosionsinhibierende Wirkung vermindert wird. Die durch diese Ausfällungen gebildeten Ablagerungen können darüber hinaus die Funktionsweise von Motoren, Motorbestandteilen oder Teilen des Kraftstoffsystems, insbesondere dem Einspritzsystem, speziell den Einspritzpumpen oder -düsen, beeinträchtigen.A disadvantage of these corrosion inhibitors is that they tend to precipitate, especially in the presence of calcium ions, thereby reducing their corrosion-inhibiting effect. The deposits formed by these precipitations may also affect the operation of engines, engine components or parts of the fuel system, in particular the injection system, especially the injection pumps or nozzles.
Unter dem "Einspritzsystem" wird dabei der Teil des Kraftstoffsystems in Kraftfahrzeugen von Kraftstoffpumpe bis einschließlich Injektorauslass verstanden. Als "Kraftstoffsystem" werden dabei die Bauteile von Kraftfahrzeugen verstanden, die mit dem jeweiligen Kraftstoff in Kontakt stehen, bevorzugt der Bereich von Tank bis einschließlich Injektorauslass.The term "injection system" is understood to mean the part of the fuel system in motor vehicles from the fuel pump through the injector outlet. In this case, the term "fuel system" is understood to mean the components of motor vehicles that are in contact with the respective fuel, preferably the area from the tank up to and including the injector outlet.
Es stelle eine Ausführungsform der vorliegenden Erfindung dar, daß die erfindungsgemäßen Verbindungen gegen Ablagerungen nicht nur im Einspritzsystem wirken, sondern auch im übrigen Kraftstoffsystem, hier insbesondere gegen Ablagerungen in Kraftstofffiltern und -pumpen. Es bestand daher die Aufgabe, Korrosionsinhibitoren zur Verfügung zu stellen, die eine erhöhte Verträglichkeit gegen Calcium-Ionen zeigen und dabei ihre Wirkung als Korrosionsinhibitor behalten.It is an embodiment of the present invention that the compounds of the invention against deposits not only act in the injection system, but also in the rest of the fuel system, in particular against deposits in fuel filters and pumps. It was therefore an object to provide corrosion inhibitors are available, which show an increased compatibility with calcium ions and thereby retain their effect as a corrosion inhibitor.
Die Aufgabe wird gelöst durch die anspruchsgemäße Verwendung.The problem is solved by the claimed use.
Aus
Aus keiner dieser Schriften geht hervor, daß die erfindungsgemäßen Korrosionsinhibitoren eine erhöhte Verträglichkeit gegen Calcium-Ionen aufweisen.None of these documents shows that the corrosion inhibitors according to the invention have an increased compatibility with calcium ions.

Denkbar ist auch ein Gehalt an Alkali- und/oder Erdalkalimetallen und/oder Zink von mindestens 1 Gew.ppm, bevorzugt mindestens 2 und besonders bevorzugt mindestens 3 Gew.ppm.The copolymers described have a particular advantage in fuels or lubricants, especially in fuels having a content of alkali and / or alkaline earth metals and / or zinc of at least 0.1 ppm by weight, more preferably at least 0.2 ppm by weight and very particularly preferably at least 0.3 ppm by weight and in particular at least 0.5 ppm by weight.

Es stellt einen Vorteil der beschriebenen Copolymere dar, daß sie ihre korrosionsinhibierende Wirkung auch in Gegenwart von Alkali- und/oder Erdalkalimetallen und/oder Zink zeigen, bevorzugt auch in Gegenwart von Erdalkalimetallen. Der Gehalt an Alkali- und/oder Erdalkalimetallen in Kraftstoffen rührt beispielsweise her durch Vermischung mit Alkali- und/oder Erdalkalimetallen-haltigen Schmierstoffen, beispielsweise in der Kraftstoffpumpe. Ferner können Alkali- und/oder Erdalkalimetalle aus nicht oder unzureichend entsalzten Kraftstoffadditiven stammen. beispielsweise Trägerölen. Durch das Einschleppen von Alkali- und/oder Erdalkalimetallen in die Kraftstoffe können die oben genannten Nachteile hervorgerufen werden. Eine Quelle für Zink sind beispielsweise anti-wear Additive.It is an advantage of the copolymers described that they show their corrosion-inhibiting activity even in the presence of alkali and / or alkaline earth metals and / or zinc, preferably in the presence of alkaline earth metals. The content of alkali metals and / or alkaline earth metals in fuels is obtained, for example, by mixing with alkali and / or alkaline earth metal-containing lubricants, for example in the fuel pump. Furthermore, alkali metals and / or alkaline earth metals can originate from insufficient or insufficiently desalted fuel additives. for example, carrier oils. By entraining alkali and / or alkaline earth metals in the fuels, the above-mentioned disadvantages can be caused. A source of zinc, for example, anti-wear additives.
Als Alkalimetalle zu nennen sind besonders Natrium und Kalium, insbesondere Natrium.Particular examples of alkali metals are sodium and potassium, in particular sodium.
Als Erdalkalimetalle zu nennen sind besonders Magnesium und Calcium, insbesondere Calcium.As alkaline earth metals are particularly magnesium and calcium, especially calcium.

Bevorzugt weisen die iso-Buten in einpolymerisierter Form enthaltenden Oligomere oder Polymere einen hohen Gehalt an terminal angeordneten ethylenischen Doppelbindungen (α-Doppelbindungen) auf, beispielsweise wenigstens 50 Mol-%, bevorzugt wenigstens 60 Mol-%, besonders bevorzugt wenigstens 70 Mol-% und ganz besonders bevorzugt wenigstens 80 Mol-%.Preferably, the isobutene in polymerized form containing oligomers or polymers have a high content of terminal ethylenic double bonds (α-double bonds), for example at least 50 mol%, preferably at least 60 mol%, more preferably at least 70 mol% and most preferably at least 80 mole%.
Für die Herstellung solcher iso-Buten in einpolymerisierter Form enthaltender Oligomere oder Polymere eignen sich als Isobuten-Quelle sowohl Rein-Isobuten als auch Isobuten-haltige C4-Kohlenwasserstoffströme, beispielsweise C4-Raffinate, insbesondere "Raffinat 1", C4-Schnitte aus der Isobutan-Dehydrierung, C4-Schnitte aus Steamcrackern und aus FCC-Crackern (fluid catalysed cracking), sofern sie weitgehend von darin enthaltenem 1,3-Butadien befreit sind. Ein C4-Kohlenwasserstoffstrom aus einer FCC-Raffinerieeinheit ist auch als "b/b"-Strom bekannt. Weitere geeignete Isobuten-haltige C4-Kohlenwasserstoffströme sind beispielsweise der Produktstrom einer Propylen-Isobutan-Cooxidation oder der Produktstrom aus einer Metathese-Einheit, welche in der Regel nach üblicher Aufreinigung und/oder Aufkonzentrierung eingesetzt werden. Geeignete C4-Kohlenwasserstoffströme enthalten in der Regel weniger als 500 ppm, vorzugsweise weniger als 200 ppm, Butadien. Die Anwesenheit von 1-Buten sowie von cis- und trans-2-Buten ist weitgehend unkritisch. Typischerweise liegt die Isobutenkonzentration in den genannten C4-Kohlenwasserstoffströmen im Bereich von 40 bis 60 Gew.-%. So besteht Raffinat 1 in der Regel im wesentlichen aus 30 bis 50 Gew.-% Isobuten, 10 bis 50 Gew.-% 1-Buten, 10 bis 40 Gew.-% cis- und trans-2-Buten sowie 2 bis 35 Gew.-% Butanen; beim erfindungsgemäßen Polymerisationsverfahren verhalten sich die unverzeigten Butene im Raffinat 1 in der Regel praktisch inert und nur das Isobuten wird polymerisiert.Both isobutene and isobutene-containing C4 hydrocarbon streams, for example C4 raffinates, in particular "raffinate 1", C4 cuts from isobutane are suitable as isobutene source for the preparation of such isobutene in polymerized form containing oligomers or polymers Dehydrogenation, C4 cuts from steam crackers and fluid catalysed cracking (FCC) crackers provided that they are substantially freed from 1,3-butadiene contained therein. A C4 hydrocarbon stream from an FCC refinery unit is also known as a "b / b" stream. Further suitable isobutene-containing C4 hydrocarbon streams are, for example, the product stream of a propylene-isobutane co-oxidation or the product stream from a metathesis unit, which are generally used after customary purification and / or concentration. Suitable C4 hydrocarbon streams typically contain less than 500 ppm, preferably less than 200 ppm, butadiene. The presence of 1-butene and of cis and trans-2-butene is largely uncritical. Typically, the isobutene concentration in said C4 hydrocarbon streams is in the range of 40 to 60 weight percent. So there is raffinate 1 generally consists essentially of 30 to 50% by weight of isobutene, 10 to 50% by weight of 1-butene, 10 to 40% by weight of cis- and trans-2-butene and 2 to 35% by weight butanes; In the polymerization process according to the invention, the unsubstituted butenes in the raffinate 1 are generally virtually inert and only the isobutene is polymerized.
In einer bevorzugten Ausführungsform setzt man als Monomerquelle für die Polymerisation einen technischen C4-Kohlenwasserstoffstrom mit einem Isobuten-Gehalt von 1 bis 100 Gew.-%, insbesondere von 1 bis 99 Gew.-%, vor allem von 1 bis 90 Gew.-%, besonders bevorzugt von 30 bis 60 Gew.-%, insbesondere einen Raffinat 1-Strom, einen b/b-Strom aus einer FCC-Raffinerieeinheit, einen Produktstrom einer Propylen-Isobutan-Cooxidation oder einen Produktstrom aus einer Metathese-Einheit ein.In a preferred embodiment, the monomer used for the polymerization is a technical C 4 -hydrocarbon stream having an isobutene content of from 1 to 100% by weight, in particular from 1 to 99% by weight, especially from 1 to 90% by weight. , more preferably from 30 to 60% by weight, in particular a raffinate 1 stream, a b / b stream from an FCC refinery unit, a product stream of a propylene-isobutane co-oxidation or a product stream from a metathesis unit.
Insbesondere bei Verwendung eines Raffinat 1-Stromes als Isobutenquelle hat sich die Verwendung von Wasser als alleinigem oder als weiterem Initiator bewährt, vor allem wenn man bei Temperaturen von -20°C bis +30°C, insbesondere von 0°C bis +20°C, polymerisiert. Bei Temperaturen von -20°C bis +30°C, insbesondere von 0°C bis +20°C, kann man bei Verwendung eines Raffinat 1-Stromes als Isobutenquelle jedoch auch auf den Einsatz eines Initiators verzichten.In particular, when using a raffinate 1 stream as the isobutene source, the use of water has proved to be the sole or as a further initiator, especially if at temperatures from -20 ° C to + 30 ° C, in particular from 0 ° C to + 20 ° C, polymerized. At temperatures of -20 ° C to + 30 ° C, in particular from 0 ° C to + 20 ° C, but you can dispense with the use of a raffinate 1 stream as Isobutenquelle but also on the use of an initiator.
Das genannte Isobuten-haltige Monomerengemisch kann geringe Mengen an Kontaminanten wie Wasser, Carbonsäuren oder Mineralsäuren enthalten, ohne dass es zu kritischen Ausbeute- oder Selektivitätseinbußen kommt. Es ist zweckdienlich, eine Anreicherung dieser Verunreinigungen zu vermeiden, indem man solche Schadstoffe beispielsweise durch Adsorption an feste Adsorbentien wie Aktivkohle, Molekularsiebe oder Ionenaustauscher, aus dem Isobuten-haltigen Monomerengemisch entfernt.Said isobutene-containing monomer mixture may contain small amounts of contaminants such as water, carboxylic acids or mineral acids, without resulting in critical yield or selectivity losses. It is expedient to avoid an accumulation of these impurities by removing such pollutants from the isobutene-containing monomer mixture, for example by adsorption on solid adsorbents such as activated carbon, molecular sieves or ion exchangers.
Es können, wenn auch weniger bevorzugt, auch Monomermischungen von Isobuten beziehungsweise des Isobuten-haltigen Kohlenwasserstoffgemischs mit olefinisch ungesättigten Monomeren, welche mit Isobuten copolymerisierbar sind, umgesetzt werden. Sofern Monomermischungen des Isobutens mit geeigneten Comonomeren copolymerisiert werden sollen, enthält die Monomermischung vorzugsweise wenigstens 5 Gew.-%, besonders bevorzugt wenigstens 10 Gew.-% und insbesondere wenigstens 20 Gew.-% Isobuten, und vorzugsweise höchstens 95 Gew.-%, besonders bevorzugt höchstens 90 Gew.-% und insbesondere höchstens 80 Gew.-% Comonomere.Although less preferred, monomer mixtures of isobutene or of the isobutene-containing hydrocarbon mixture can also be reacted with olefinically unsaturated monomers which are copolymerizable with isobutene. If monomer mixtures of isobutene are to be copolymerized with suitable comonomers, the monomer mixture preferably contains at least 5% by weight, particularly preferably at least 10% by weight and in particular at least 20% by weight of isobutene, and preferably at most 95% by weight preferably at most 90% by weight and in particular at most 80% by weight of comonomers.
In einer bevorzugten Ausführungsform weist das Stoffgemisch der Olefine (B) und optional (C) gemittelt auf ihre Stoffmengen mindestens 12 Kohlenstoffatome auf, bevorzugt mindestens 14, besonders bevorzugt mindestens 16 und ganz besonders bevorzugt mindestens 17 Kohlenstoffatome auf.In a preferred embodiment, the substance mixture of the olefins (B) and optionally (C) averaged to their substance amounts at least 12 carbon atoms, preferably at least 14, more preferably at least 16 and most preferably at least 17 carbon atoms.
So weist beispielsweise ein 2:3-Gemisch aus Docosen und Tetradecen einen gemittelten Wert für die Kohlenstoffatome von 0,4 x 22 + 0,6 x 14 = 17,2 auf.For example, a 2: 3 mixture of docoses and tetradecene has an average value for the carbon atoms of 0.4 x 22 + 0.6 x 14 = 17.2.
Die Obergrenze ist weniger relevant und beträgt in der Regel nicht mehr als 60 Kohlenstoffatome, bevorzugt nicht mehr als 55, besonders bevorzugt nicht mehr als 50, ganz besonders bevorzugt nicht mehr als 45 und insbesondere nicht mehr als 40 Kohlenstoffatome.The upper limit is less relevant and is usually not more than 60 carbon atoms, preferably not more than 55, more preferably not more than 50, most preferably not more than 45 and especially not more than 40 carbon atoms.
