Abstract

Fuels for prime movers, in particular internal combustion engines, contain dicyclopentadiene as an anti-knock compound.

Description

Die Erfindung betrifft Kraftstoffe für Brennkraftmaschinen, insbesondere Verbrennungsmotoren, enthaltend Dicyclopentadien als Octanzahl-erhöhendes Mittel.The invention relates to fuels for internal combustion engines, in particular internal combustion engines, containing dicyclopentadiene as an octane-increasing agent.

Es ist bekannt, den Kraftstoffen zur Erhöhung der Klopffestigkeit metallorganische Verbindungen wie Bleitetramethyl oder -ethyl oder Metallcarbonyle wie Eisenpentacarbonyl, Cyclopentadienylmangantricarbonyl, Manganpentacarbonyl, Mg-Cyclopentadienyl oder Ferrocen als Antiklopfmittel zuzusetzen.It is known to add organometallic compounds such as lead tetramethyl or ethyl or metal carbonyls such as iron pentacarbonyl, cyclopentadienylmanganese tricarbonyl, manganese pentacarbonyl, Mg-cyclopentadienyl or ferrocene to the fuels to increase the knock resistance as anti-knock agents.

Alle diese Substanzen haben den Nachteil, daß sich deren Verbrennungsprodukte (Metalloxide) in störender Weise sowohl im Motor als auch in der Umwelt ablagern und so zur Kontamination führen.All these substances have the disadvantage that their combustion products (metal oxides) are deposited in a disruptive manner both in the engine and in the environment and thus lead to contamination.

Aus der US-4 387 257 ist es bekannt, Kraftstoffen als Antiklopfmittel bicyclische Diolefine zuzusetzen. Als Vertreter dieser Bicyclen ist ausschließlich Norbornadien und seine Derivate genannt. Die damit erreichte Erhöhung der ROZ (Researchoctanzahl) ist jedoch ausweislich der dort angegebenen Versuche gering.From US-4,387,257 it is known to add bicyclic diolefins to fuels as anti-knock agents. Only norbornadiene and its derivatives are mentioned as representatives of these bicycles. The increase in RON (research octane number) achieved in this way is, however, small, according to the tests specified there.

Der Erfindung lag daher die Aufgabe zugrunde, Kraftstoffe mit Additiven zur Verfügung zu stellen, die nicht zur Bildung von Metalloxiden führen und trotzdem eine merkliche Erhöhung der Klopffestigkeit, d.h. der Octanzahl, bewirken.The invention was therefore based on the object of providing fuels with additives which do not lead to the formation of metal oxides and nevertheless a noticeable increase in the knock resistance, i.e. the octane number.

Es wurde nun überraschenderweise gefunden, daß durch Zusatz von gegebenenfalls C₁-C₄-alkylsubstituierten Dicyclopentadien eine extrem octanzahlerhöhende Wirkung bei gleichzeitig optimaler Verbrennung erzielt wird.It has now surprisingly been found that the addition of optionally C₁-C₄-alkyl-substituted dicyclopentadiene achieves an extremely octane-increasing effect with optimal combustion at the same time.

Die Zusatzmengen betragen dabei je nach Anforderung zwischen 0,01 und 60 Vol.%, vorzugsweise 0,1 bis 30 Vol.%, insbesondere 0,1 bis 15 Vol.%, bezogen jeweils auf den fertigen Gesamtkraftstoff. Die Entstehung schädlicher Emissionen wird dadurch ausgeschlossen.The additional amounts are, depending on the requirement, between 0.01 and 60% by volume, preferably 0.1 to 30% by volume, in particular 0.1 to 15% by volume, based on the finished total fuel. This prevents the creation of harmful emissions.

Unter Kraftstoffen sind in der Regel Gemische von Kohlenwasserstoffen, insbesondere flüssigen Kohlenwasserstoffen, zu verstehen, die im wesentlichen aus aliphatischen Kohlenwasserstoffen mit Zusätzen von aromatischen oder cycloaliphatischen Komponenten bestehen.Fuels are generally mixtures of hydrocarbons, in particular liquid hydrocarbons, which essentially consist of aliphatic hydrocarbons with additions of aromatic or cycloaliphatic components.

Kraftstoffe, in denen das Dicyclopentadien insbesondere mit Vorteil eingesetzt werden kann, sind Kraftstoffe mit einer ROZ über 95. (Die Researchoctanzahl (ROZ) wird in der DIN 51 756 definiert.)Fuels in which dicyclopentadiene can be used with particular advantage are fuels with an RON above 95. (The research octane number (RON) is defined in DIN 51 756.)

Bei den genannten Kraftstoffen handelt es sich z.B. um Eurosuper oder Superplus-Qualitäten nach DIN 51 607, um Kraftstoffe nach DIN 51 600 (mit 0,15 g Pb/l), aber auch um Kraftstoffe für Hoch- und Höchstleistungsmaschinen.The fuels mentioned are e.g. Eurosuper or Superplus qualities according to DIN 51 607, fuels according to DIN 51 600 (with 0.15 g Pb / l), but also fuels for high and high performance machines.

Die erfindungsgemäßen Kraftstoffe können auch Methanol und Ethanol oder höhere Alkohole als Lösungsvermittler, Aceton oder Ether, wie z.B. Methyl-tert.butyl-ether oder ähnliche Verbindungen enthalten.The fuels according to the invention can also contain methanol and ethanol or higher alcohols as solubilizers, acetone or ethers, such as e.g. Contain methyl tert-butyl ether or similar compounds.

Bei Dicyclopentadien handelt es sich um eine tricyclische Verbindung, deren systematischer Name Tri-cyclo-[5.2.1.02,6]deca-3,8-dien ist und die im Handel erhältlich ist (siehe Römpp, Chemielexikon, 8. Auflage, Franckh'sche Verlagshandlung, Stuttgart, 1981, S. 943).Dicyclopentadiene is a tricyclic compound whose systematic name is tri-cyclo- [5.2.1.0 2,6 ] deca-3,8-diene and which is commercially available (see Römpp, Chemielexikon, 8th edition, Franckh 'sche Verlagshandlung, Stuttgart, 1981, p. 943).

Neben dem Dicyclopentadien sind auch dessen C₁-C₄-alkylsubstituierte Derivate einsetzbar, wobei das Methylderivat bevorzugt ist.In addition to the dicyclopentadiene, its C₁-C₄-alkyl-substituted derivatives can also be used, the methyl derivative being preferred.

Die erfindungsgemäßen Kraftstoffe können neben dem Dicyclopentadien noch andere übliche Antiklopfmittel enthalten, wie z.B. Metall- und/oder Carbonylgruppen-haltige Produkte, soweit sie mit Dicyclopentadien verträglich sind.In addition to dicyclopentadiene, the fuels according to the invention can also contain other customary anti-knock agents, such as e.g. Products containing metal and / or carbonyl groups insofar as they are compatible with dicyclopentadiene.

Weiterhin kann der Kraftstoff auch andere Benzinadditive, wie z.B. Vergaserdetergents (vgl. hierzu DE-OS 38 38 918), Vergaservereisungsverhinderer (Antiicings), Korrosionsinhibitoren, Antioxidantien und/oder Einlaßsystemreiniger wie z.B. Polyisobutylamin und dessen Derivate in den wirksamen Mengen enthalten. Diese Additive sind allgemein üblich und jeweils im Handel erhältlich. Die jeweils einzusetzenden Mengen sowie die Additive im einzelnen sind dem Fachmann geläufig und mehrfach in der Literatur beschrieben, z.B. M.W. Ranney, "Fuel additives for internal combustion engines, Recent developments", 1978, und M.T. Gillies, "Chemical Additives for fuels, Development since 1978", 1982, beide erschienen bei Noyes Data Corp., Park Ridge, N.J., USA, und die dort zitierte Literatur. Weiterhin ist zu nennen: "Fuel additives: Keys to quality, distribution and performance", Automotive Engineering, October 1985, S. 86-94; M. Rossenbeck in Katalysatoren, Tenside, Mineralöladditive, Hrsg. J. Falbe, U. Hasserodt, S. 223 f., G. Thieme Verlag, Stuttgart, 1978.Furthermore, the fuel can also contain other gasoline additives, such as carburetor detergents (cf. DE-OS 38 38 918), carburetor icing preventers (anti-icings), corrosion inhibitors, antioxidants and / or inlet system cleaners such as polyisobutylamine and its derivatives in the effective amounts. These additives are common and are commercially available. The amounts to be used in each case and the additives in detail are familiar to the person skilled in the art and have been described several times in the literature, for example MW Ranney, "Fuel additives for internal combustion engines, Recent developments", 1978, and MT Gillies, "Chemical Additives for fuels, Development since 1978 ", 1982, both published by Noyes Data Corp., Park Ridge, NJ, USA, and the literature cited there. Also to be mentioned: "Fuel additives: Keys to quality, distribution and performance", Automotive Engineering, October 1985, pp. 86-94; M. Rossenbeck in catalysts, surfactants, mineral oil additives, ed. J. Falbe, U. Hasserodt, p. 223 f., G. Thieme Verlag, Stuttgart, 1978.

Die Brennkraftmaschinen umfassen Kolbentriebwerke und Gasturbinen, wobei als Kolbentriebwerke Verbrennungsmotoren, insbesondere Ottomotoren, bevorzugt zu nennen sind.The internal combustion engines include piston engines and gas turbines, with internal combustion engines, in particular gasoline engines, to be mentioned as preferred piston engines.

Mit den erfindungsgemäßen Kraftstoffen wird nicht nur eine Erhöhung der Octanzahl und der Klopffestigkeit erreicht, sondern es wird darüber hinaus auch das Brennverhalten eines Ottomotors allgemein optimiert. So wird auch eine optimale Brennstoffausnutzung erreicht, so daß sich der spezifische Verbrauch erniedrigt.The fuels according to the invention not only increase the octane number and knock resistance, they also optimize the combustion behavior of a gasoline engine in general. In this way, optimal fuel utilization is also achieved, so that the specific consumption is reduced.
