Description

Bisher wurden die Antiklopfmittel bei der Anwendung· in durch, Funkenbildung gezündeten Verbrenaungskraftmaschinen immer dem Treibstoff zugesetzt. Es wurde auch schon früher vorgeschlagen, die Antiklopfmittel, wie z. B. Bleitetra,-äthyl, den Schmierölen im Kurbelgehäuse zuzusetzen. Diese Vorschläge haben sich jedoch in der Praxis nicht bewährt, da das Mittel aus dem öl rasch verlorengeht. Überraschenderweise wurde nun gefunden-, daß Antiklopfmittel der allgemeinen Formel M R2, wobei M ein Eisen-, Nickel-, Ruthenium- oder Osmiumatom bedeutet und R ein substituierter oder nicht substituierter Cyclopentadienylrest ist, direkt dien Schmierölen im Kurbelgehäuse von Verbrennungskraftmaschinen. züge- setzt werden können und auch noch.von dieser Stelle aas ein Klopfen im Motor verhindern. Darüber hinaus verschwinden sie viel weniger rasch aus dem öl, als es bei den. bekannten Antiklopfmitteln der Fall ist. So führt Dicyclopentadienyleisen, das in einem mineralischen Schmieröl gelöst ist, bei der Anwendung in einem Motor zu einer Klopffreiheit desselben, die viermal so lange vorhält als bei Anwendung einer gleichen Menge an Bleitetraäthyl.
Die vorliegende Erfindung betrifft daher Schmiermittelzusammensetzungen, die1 für die Verwendung in Kurbelgehäusen von Verbrennungs-
kraftmaschinen geeignet sind und die aus einem Schmieröl bestellen, das eine kleine Menge einer organometallischm Verbindung- von der allgemeinen Formel M R2 enthält, wobei M und R die
. 5 oben angegebene Bedeutung haben.
Typische Substituienten, welche bei diesen neuen Antiklopfmitteln vorhanden sein können, sind' Hydroxyl-, Amino, Cyan-, Mercapto-, Äther-, Thioäthar-, Acyl-, Keto-, Carbalkoxy-, Carboxyl- und
ίο Sulfönsäuregruppen sowie Kohlenwasserstoff gruppen, wie z. B. Alkyl-, Alkenyl-, Cycloalkyl-, Aryl-, Alkaryl- und Aralkylgruppen. Beispiele für brauchbare substituierte Verbindungen sind Diacetyldicyclopentadienyleisen, welches dadurch hergestellt werden kann, daß man Dicyolopentadienyleisen einer Friedel-Crafts-Reaktion mit Acetylchlorid in Gegenwart von Aluminiumchlorid unterwirft, und DicydopentadienyleisenrDicarbonsäure, welche durch Oxydation des Diacetyldicyclopenta-
ao dienyleisens erhalten werden kann. Aus dieser zuletzt erwähnten Dicarbonisäure können die entsprechenden Salze, Ester, Amide und Cyanverbindungen hergestellt werden. Alle diese Verbindungen sind als Antiklopfmittelzusätze brauchbar. Besonders gute Ergebnisse werden mit Verbindungen der •angegebenen' Art erhalten, bei welchen die Cyclopentadienylreste mit Äthyl-, Propyl-, Butyl- oder
• höheren Alkylgruppen substituiert sind. Vertreter dieser Verbindungsklasse sind Di-(äthylcyclopentadienyl) -eisen und Di-(butylcyclopentadienyl)-eisen. Im allgemeinen können die erfindungsgemäß verwendeten Substitutionsprodukte des Dicyclopentadienyleisens nach den gleichen Verfahren, wie sie zur Herstellung von Substitutionsprodukten des Benzols Anwendung findien, hergestellt werden, da Dicyclopentadienyleisen· die Eigenschaften einer aromatischen Verbindung besitzt.
Das zur Herstellung der obenerwähnten S chmiermittelzusammensetzungen verwendete
Schmieröl ist vorzugsweise ein mineralisches Schmieröl, jedoch können ebenso synthetische Schmiermittel oder Mischungen von mineralischen Schmierölen mit synthetischen Schmiermitteln verwendet werden. Diese Schmiermittelzusammen-Setzungen können üblicherweise verwendete Zusätze, wie Antioxydantien, z. B. aromatische Amine, alkylierte Phenole und Aminophenole, Korrosionsverhinderer, z. B. teilweise mit Fettsäuren veresterte mehrwertige Alkohole1 und alkylsubstituierte Bernsteinsäuren, Reinigungsmittel, z. B. Metallseifen, von Fettsäuren, Naphthensäuren oder hydroxylierten aromatischen Carbonsäuren, Stockpuriktserniedriger, Antischaummittel undVerbesserungsmittel für den Viskositätsindex, enthalten.
Die Menge an Antiklopfmittelzusatz, die in die vorliegenden Schmierölzusammensetzungen einge^· arbeitet wird, hängt von mehreren Faktoren ab, wie z. B. von der besonderen Art des verwendeten Zusatzes, vom Motorentyp, in welchem die Zusammensetzung angewandt wird, und von der Art des verwendeten Treibstoffes. Im allgemeinen soll eine Menge im Bereich von 0,01 bis 5,0 Gewichtsprozent, vorzugsweise eine Menge zwischen 0,1 und 3 Gewichtsprozent, verwendet werden.
Die folgenden Biöispiele 1 und 2 erläutern die erfindungsgemäßen Schmiermittelzusammensetzungen.
Beispiel 1
Es wurde Dioyclopentadienyleisen in einem SAE-20-Mineral-Schinieröl in einem Verhältnis von' ι g pro 100 ml öl gelöst.
Diese Schmiermittelzusammensetzung verringert den Oktanbedarf des Motors, in welchem sie verwendet wurde, um 9, d. h. der Motor konnte klopffrei laufen mit einem Treibstoff, der eine -um 9 geringere Oktanzahl hatte als der für klopffreies Laufen benötigte Treibstoff bei Verwendung von unbehandeltem Schmieröl.

PATENTANSPRÜCHE: Es wurde Dicyclopentadienyleisen in einem mit üblichem Zusatz · versehenen Schmieröl im Verhältnis 0,5 g pro 100 ml öl gelöst. Diese Schmiermittelzusammensetzung verminderte den Oktanbedarf des Motors, in welchem sie angewandt wurde, um 5.
1. Schmiermittel für Kurbelgehäuse von Verbrennungskraftmaschinen, dadurch gekennzeichnet, daß es aus einem Schmieröl und einem kleineren Teil einer metallorganischen Verbindung der allgemeinen Formel M R2 besteht, wobei M ein Atom von Eisen, Nickel, Ruthenium oder Osmium und R einen substituierten oder unsubstituierten Cyclopentadienylrest bedeuten.
