Description
Gegenstand der Erfindung sind Schmieröle, die als Reinigungsmittel N-Dialkylaminoalkyl-monoalkenylsuccinimide
enthalten.
Alkenyl-bernsteinsäureanhydride sowie zahlreiche ihrer Derivate sind in der Technik bekannt. So gelten
z. B. Alkenyl-bernsteinsäureanhydride, deren Alkenylrest 5 bis 20 Kohlenstoffatome enthält, in Schmiergemischen
als Antikorrosionsmittel, und Produkte aus der Umsetzung derartiger Alkenyl-bernsteinanhydride
mit Monoaminen werden in Schmierölgemischen als Antikorrosionsmittel für Eisen, verwendet.
Obige bekannte Alkenyl-succinimide sind jedoch als Reinigungsmittel für Schmierölgemische nicht
geeignet. Hingegen erweisen sich die erfindungsgemäßen Alkenyl-succinimide für diesen Zweck als
gute Reinigungsmittel.
Es sind Motortreibstoffe bekannt, die als Oxydationsinhibitor das Reaktionsprodukt aus einer
Monocarbonsäure und einem Polyalkylenimin enthalten.
Die heutigen Verbrennungsmotoren laufen mit hoher Geschwindigkeit und hoher Verdichtungszahl.
Bei dem ständigen Halten und Anfahren im heutigen Stadtverkehr, dem sehr viele Kraftfahrzeuge während
des größten Teil der Fahrzeit ausgesetzt sind, erreichen die Verbrennungsmotoren jedoch nicht die
wirksamste Arbeitstemperatur. Unter den im Stadtverkehr herrschenden Bedingungen bilden sich große
Mengen von als einzelne Teilchen vorliegenden Oxydationsprodukten, die, da sie über die Kolbenringe
hinausgeblasen werden, das Kurbelgehäuse des Motors erreichen. Der größte Teil dieser als einzelne Teilchen
vorliegenden Oxydationsprodukte ist in Öl unlöslich und neigt dazu, auf den verschiedenen Teilen des
Motors, wie dem Kolben, Kolbenringen usw., Ablagerungen zu bilden. Zur Verhinderung derartiger
Ablagerungen müssen den Schmierölgemischen Reinigungsmittel zugesetzt werden, um die polymeren
Produkte in stark dispergiertem Zustand zu halten.
Meistens bestehen die verschiedenen Reinigungsmittel, die dem in das Kurbelgehäuse gelangenden
ölen zugesetzt werden, um die Bildung von Schlämmen und Firnissen zu verringern, aus metallorganischen
Verbindungen, insbesondere aus solchen Verbindungen, in denen das Metall über ein Sauerstoffatom an
eine organische Gruppe gebunden ist. Obgleich diese metallhaltigen organischen Verbindungen als Reinigungsmittel
eine gewisse Wirksamkeit besitzen und die Vorstufen der Ablagerungen in dem Öl selbst
dispergieren, damit sich letztere nicht auf den verschiedenen Teilen des Motors ablagern können,
Schmieröle

haben sie den Nachteil, daß sie im Motor Ascheablagerungen bilden, die Zündkerzen und
Ventile verschmutzen, dadurch die Leistung des Motors herabmindern und eine Frühzündung mitverursachen.
Ziel der Erfindung sind daher Schmieröle, die metallfreie Reinigungsmittel enthalten.
Es wurde gefunden, daß man für den Schwerbetrieb besonders geeignete Schmierölgemische dadurch erhält, daß man Ölen mit Schmierölviskosität 0,25 bis 5,0 Gewichtsprozent, bezogen auf das Gesamtschmieröl, bestimmter N-Dialkylaminoalkyl-monoalkenyl-succinimide zusetzt.
Es wurde gefunden, daß man für den Schwerbetrieb besonders geeignete Schmierölgemische dadurch erhält, daß man Ölen mit Schmierölviskosität 0,25 bis 5,0 Gewichtsprozent, bezogen auf das Gesamtschmieröl, bestimmter N-Dialkylaminoalkyl-monoalkenyl-succinimide zusetzt.
Die N-Dialkylaminoalkyl-monoalkenyl-succinimide
sind in Schmierölgemischen besonders wirksame Reinigungsmittel. Bei Verwendung von Schmierölgemischen,
die diese Alkenyl-succinimide enthalten, bleiben die verschiedenen Teile von Diesel- und
Benzinmotoren sogar unter harten Arbeitsbedingungen bis zu einem erstaunlichen Grade frei von Ablagerungen
und Firnissen.

Die erfindungsgemäß eingesetzten N-Dialkylaminoalkyl-monoalkenyl-succinimide
können durch, folgende Formel wiedergegeben werden:
R-CH-C
N — R1 —
CH2-C
,R2
1R3
1R3
in der R einen Alkenylrest mit 30 bis 200 Kohlenstoffatomen, R1 einen zweiwertigen Alkylenrest und
R2 und R3 Alkylreste bedeuten. Die Summe der Kohlenstoffatome in R1, R2 und R3 beträgt 3 bis 10.
R besteht vorzugsweise aus einem Polymeren eines Olefins mit 2 bis 5 Kohlenstoffatomen, wobei das
Molekulargewicht des Polymeren zwischen 400 und 3000, vorzugsweise zwischen etwa 900 und etwa 1200
liegt. Beispiele solcher Olefine sind Äthylen, Propylen, 1-Buten, 2-Buten, Isobuten sowie deren
Gemische. Da das im einzelnen angewendete Verfahren zur Polymerisation der Olefine für die Herstellung der
neuen, vorliegend beschriebenen Verbindung unwesentlich ist, kann hierfür jedes der zahlreichen
zur Verfügung stehenden Verfahren angewendet werden.
Als Alkylenrest kann für R1 ein zweiwertiger Äthylenrest, Propylenrest, Butylenrest usw. verwendet
werden. Alkylreste der Symbole R2 und R3 sind Methyl, Äthyl, Propyl usw. Vorzugsweise enthält
R1 3 Kohlenstoffatome und R2 und R3 jeweils 1 Kohlenstoffatom.
Amin- Reaktionsteilnehmer für die Herstellung von N-Dialkylaminoalkyl-monoalkenyl-succinimiden
sind z. B.: Dimethylaminomethylamin, Dimethylaminoäthylamin, Dimethylaminopropylamin, Dimethylaminobutylamin,
Dimethylaminoheptylamin, Diäthylaminomethylamin, Diäthylaminopropylamin, Diäthylaminoamylamin, Dipropylaminopropylamin,
Methylpropylaminoamylamin und Propylbutylaminoäthylamin.
Das Verfahren zur Herstellung der Succinimide, für das im Rahmen vorliegender Erfindung kein
Schutz begehrt wird, kann wie folgt durchgeführt werden:
Ein Polyolefin wird mit Maleinsäureanhydrid unter Bildung eines Monoalkenylsuccinsäureanhydrids umgesetzt,
das weiter mit einem Diäthylaminoalkylamin in etwa äquimolaren Mengen zur Reaktion gebracht
wird und dabei das gewünschte N-Dialkylaminoalkyl-monoalkenyl-succinimid
bildet.
Da die Umsetzung des Polyolefins mit dem Maleinsäureanhydrid
nicht immer bis zur Vollständigkeit fortschreiten wird, kann das erhaltene Alkenylbernsteinsäureanhydrid
etwas nicht umgesetztes Polyolefin enthalten. Da eine Abtrennung dieses nicht umgesetzten Polyolefins in diesem Stadium unzweckmäßig
sein kann, wird das erhaltene Imid aus der Umsetzung des Alkenyl-bernsteinsäureanhydrids mit
dem Diamin als Verunreinigung dieses Polyolefin enthalten, das bei der Herstellung von Schmierölgemischen
ein Verdünnungsmittel sein kann. Gewünschtenfalls kann jedoch dieses nicht umgesetzte
Polyolefin ζ. B. durch Aceton oder Methanol aus einer Kohlenwasserstofflösung ausgefällt und entfernt
werden.
In nachstehenden Beispielen wird die Herstellung von N-Dialkylaminoalkyl-monoalkenyl-succinimiden
beschrieben.
Beispiel 1
Herstellung von Polybutenyl-bernsteinsäureanhydrid
Herstellung von Polybutenyl-bernsteinsäureanhydrid
Unter einer Stickstoffatmosphäre wird ein Gemisch aus 1000 g (1 Mol) Polybuten mit einem Molekulargewicht
von etwa 1000 und 98 g (1 Mol) Maleinsäureanhydrid unter Rühren 24 Stunden auf 210° C
erhitzt. Dann wird das Reaktionsgemisch auf 66° C abgekühlt, und man gibt 700 cm3 Hexan hinzu. Nach
Entfernung des Hexans aus dem Filtrat durch Vakuumdestillation wird das Produkt 1 Stunde auf 177° C bei
einen! absoluten Druck von 10 mm Hg gehalten, um Spuren von Maleinsäureanhydrid zu entfernen. Die
Verseifungszahl des auf diese Weise hergestellten rohen Polybutenyl-bernsteinsäureanhydrids betrug 79.
Herstellung von N-Dimethylaminopropylmono-(polybutenyl)-succinimid
Unter einer Stickstoffatmosphäre wurden 21,3 g (0,21 Mol) Dimethylaminopropylamin und 150 g
(0,09 Mol) Polybutenyl-bernsteinsäureanhydrid des Beispiels 1 unter Rühren vermischt und das Gemisch
1 Stunde auf 260° C erhitzt. Dann wurde der absolute Druck unter Beibehaltung dieser Temperatur während
30 Minuten auf etwa 200 mm Hg verringert, um die Entfernung von Wasser und überschüssigem Amin
zu erleichtern. Unter Beibehaltung dieses verringerten Druckes ließ man das Reaktionsgemisch dann auf
Raumtemperatur abkühlen. Das Produkt enthielt 1,7 7o Stickstoff (theoretische Menge = 1,8%). Die
Identität des N-Dimethylaminopropylalkenyl-succinimids
wurde durch Infrarot-Spektroskopie nachgewiesen.
Nachstehende Tabelle 1 enthält weitere Daten für die Herstellung von N-Dialkylaminoalkyl-monoalkenyl-succinimiden.
Als Polyamin wurde Dimethylpropylamin verwendet, und der Alkenylrest des Alkenyl-succinimids bestand aus einem Polybuten

Als Basisöle für Schmierölgemische solcher Alkenylsuccinimide
kann eine Vielzahl von Schmierölen eingesetzt werden. Hierzu gehören Schmieröle auf
naphthenischer Basis, Paraffinbasis und Mischbasis, andere Kohlenwasserstoff-Schmiermittel, z. B. Schmieröle
aus Kohleprodukten, und synthetische öle, z. B. Alkylenpolymere (wie Polymere von Propylen, Butylen
usw. sowie deren Gemische), Polymere der Alkylenoxydart (z. B. Alkylenoxydpolymere aus der in
Gegenwart von Wasser oder Alkoholen, z. B. Äthylenalkohol, durchgeführten Polymerisation von Alkylenoxyd,
z. B. Propylenoxyd usw.), Dicarbonsäureester (z. B. Ester von Dicarbonsäuren, wie Adipinsäure,
Azelainsäure, Korksäure, Sebacinsäure, Alkanolbernsteinsäure, Fumarsäure, Maleinsäure, mit Alkoholen,
wie Butylalkohol, Hexylalkohol, 2-Äthylhexylalkohol,
Dodecylalkohol), flüssige Ester von Phosphorsäuren, Alkylbenzole, Polyphenyle (z. B.
Biphenyle und Terphenyle), Alkyldiphenyläther, Siliconpolymere (z. B. Tetraäthylsilicat, Tetraisopropylsilicate,
Tetra-(4-methyl-2-tetraäthyl)-silicat, Hexyl-(4-methyl-2-pentoxy)-disiloxan,
Poly-(methyl)-siloxan und Poly-(methylphenyl)-siloxan).
Obige Basisöle können entweder einzeln oder im Gemisch miteinander, soweit sie mischbar sind oder
durch gegenseitige Lösungsmittel mischbar gemacht wurden, verwendet werden.
In der nachstehenden Tabelle II sind Daten über die Wirksamkeit von N-Dialkylaminoalkyl-monoalkenyl-succinimiden
als Schmierölzusätze zusammengestellt.
Als Succinimid wurde ein N-Dimethylaminopropylalkenyl-succinimid
verwendet, dessen Alkenylrest ein Molekulargewicht von annähernd 1000 aufwies und
aus einem Isobutenpolymeren bestand.
Als Basisöl wurde ein SAE-10-Basisöl verwendet.
Die Daten wurden in einem Caterpillar-L-1-Versuch ermittelt, der 120 Stunden unter Mil-L-2104-Bedingungen
durchgeführt wurde.
Die Kolbenverfärbungszahl bezieht sich auf den Verfärbungswert des Kolbens. Nach dem Motorentest
werden die drei Kolbenstege visuell untersucht, ein vollkommen schwarzer Kolbensteg erhält die
Kolbenverfärbungszahl 800, während ein vollkommen sauberer Steg die Kolbenverfärbungszahl 0 erhält.
Kolbenstege, deren Verfärbungswert zwischen vollkommen Schwarz und vollkommen Weiß liegt, erhalten
Kolbenverfärbungszahlen innerhalb des genannten Bereiches im Verhältnis zu dem Ausmaß und Grad
ihrer Verdunkelung.
Die »Rillenablagerungszahl« bezieht sich auf die prozentualen Ablagerungen in den Rillen der Kolbenringe.
Eine saubere Rille erhält den Wert 0, während eine mit Ablagerungen angefüllte Rille die Zahl 100
ίο erhält.

Aus den in der nachstehenden Tabelle III wiedergegebenen Daten geht hervor, wieweit diese Alkenylsuccinimide
der Bildung von Kolbenfirnis entgegenwirken. Diese Versuche wurden in einem FL-2-Test
unter Verwendung eines Chevrolet-Motors mit sechs Zylindern bei einer Umdrehungszahl von 2500 Min.
während 40 Stunden durchgeführt. Dieser Testversuch ist in einem »Coordinating Research Council Bulletin«
unter dem Titel »Research Technique for the Determination of the Effects of Fuels and Lubricants on
the Formation of Deposits During Moderate Temperature Operation« (1948) ausführlich beschrieben.
Der Kolbenfirniswert wird durch visuelle Feststellung der Firnismenge auf einem Kolbenmantel
bestimmt, wobei ein sauberer Kolben den Wert »10« und ein mit schwarzem Firnis völlig überzogener
Kolben den Wert »0« erhält. Dieser Kolbenfirniswert steht in Wechselbeziehung zur Straßenleistung.
Als Dithiophosphat wurde ein Zinksalz eines Dialkyldithiophosphatgemisches
verwendet, wobei einer der Alkylreste 4 Kohlenstoffatome und der andere
5 Kohlenstoffatome enthielt.
