Die heutigen Verbrennungskraftmaschinen werden mit hoher Tourenzahl und hohem Verdichtungsgrad
betrieben. Im Stadtverkehr erreicht der Explosionsmotor nicht die -wirksamste Betriebstemperatur. Hierbei
bilden sich große Mengen teilweise oxydierter Produkte, die an den Kolbenringen vorbei in das
Kurbelgehäuse des Motors gelangen. Die meisten dieser teilweise oxydierten Produkte lösen sich nicht
in öl und bilden leicht auf den verschiedenen Antriebsteilen des Motors, wie Kolben, Kolbenringen,
Ablagerungen. Um die Ablagerung dieser Produkte auf den verschiedenen Motorteilen zu verhindern,
müssen den Schmierölen sogenannte Reinigungsmittel zugesetzt werden, die diese polymeren Produkte
stark dispergiert halten.
In den meisten Fällen handelt es sich bei den verschiedenen Reinigungsmitteln, die den Kurbelgehäuseölen
zur Verringerung solcher Harz- und Lackbildung zugesetzt werden, um metallorganische Verbindungen,
besonders um solche Verbindungen, bei denen das Metall durch ein Sauerstoffatom mit der
organischen Gruppe verbunden ist. Diese metallhaltigen, organischen Verbindungen wirken in gewisser
Weise reinigend, indem sie die Vorläufer solcher Ablagerungen im öl selbst dispergieren und
die Bildung zusätzlicher Ablagerungen auf den Motorenteilen verhindern. Sie haben jedoch den
Nachteil, daß sich Ascheablagerungen im Motor bilden. Diese Ascheablagerungen verringern die
Leistungsfähigkeit des Motors, indem sie die Zündkerzen und Ventile verschmutzen und Frühzündungen
begünstigen.
Alkenylbernsteinsäureanhydride und zahlreiche davon abgeleitete Verbindungen sind bekannt. Alkenylbernsteinsäureanhydride
z. B., deren Alkenylrest 5 bis 20 Kohlenstoffatome enthält, sind als korrosionshemmende
Mittel für Schmieröle beschrieben. Auch Produkte, die durch Umsetzung solcher Alkenylbernsteinsäureanhydride mit Monoaminen
hergestellt werden, werden als die Korrosion von Eisen hemmende Mittel für Schmieröle empfohlen.
Diese Alkenylsuccinimide eignen sich jedoch nicht als Reinigungsmittel für Schmieröle.
Es wurde nun gefunden, daß man besonders für starke Beanspruchung geeignete Schmieröle für Verbrennungskraftmaschinen
erhält, wenn man den Schmierölen bestimmte N-Dialkylaminoalkylmonoalkenylsuccinimide
und bestimmte Metalldithiophosphate in einem bestimmten Molverhältnis zusetzt.
N-Dialkylaminoalkylalkenylsuccinimide haben sich
als besonders wirksame Reinigungsmittel für Schmieröle erwiesen. Bei Verwendung von Schmierölen, die

Metalldithiophosphate und Alkenylsuccinimide enthalten, bleiben alle Teile von mit Dieselöl oder
Benzin betriebenen Motoren in bemerkenswerter Weise frei von Ablagerungen und Harzen, selbst bei
höchster Beanspruchung.
N - Dialkylaminoalkylmonoalkenylsuccinimide, in denen der Alkenylrest aus 30 bis 200 Kohlenstoffatomen
und in denen der Dialkylaminoalkylrest insgesamt aus 3 bis 10 Kohlenstoffatomen besteht,
können durch die Formel wiedergegeben werden:
R — CH- c
N —R' —N
CH2-C
in welcher R einen Alkenylrest mit 30 bis 200 Kohlenstoffatomen, R' einen zweiwertigen Alkylenrest und
R" und R'" Alkylreste bedeuten. Die Summe der in R', R" und R'" enthaltenen Kohlenstoffatome liegt
zwischen 3 und 10, d. h., R', R" und R'" enthalten insgesamt nicht mehr als 10 Kohlenstoffatome.
Besonders brauchbar sind die Produkte, in denen R ein Olefinpolymeres mit 2 bis 5 Kohlenstoff-
609 758/276
atomen ist, das ein Molekulargewicht zwischen 400 und 3000, insbesondere zwischen etwa 900 und etwa
1200 hat. Beispiele lür solche Olefine sind Äthylen,
Propylen, 1-Buten, 2-Buten, Isobuten und Gemische davon. Für die Herstellung der erfindungsgemäßen
Verbindungen ist es unwesentlich, nach welchen Polymerisationsverfahren die Olefine polymerisiert
werden, es kann daher eines der zahlreichen möglichen Verfahren zu diesem Zweck herangezogen
werden.
R'-Alkylenreste sind z. B. der zweiwertige Äthylenrest,
Propylenrest oder Butylenrest. Besonders bevorzugt wird es, wenn R' 3 Kohlenstoffatome und
R" und R'" je 1 Kohlenstoffatom enthalten.
Die Aminkomponenten der erfindungsgemäß eingesetzten
N - Dialkylaminoalkylalkenylsuccinimide sind /.. B. pirnethylaminornethylamin, Dimethylaminoäthylamin,

Die genannten Basisöle können einzeln oder in Kombinationen in Frage kommen, solern sie sich
mischen lassen oder durch Verwendung gegenseitiger Lösungsmittel dazu gebracht werden.
Als Schmierölzusätze werden die Alkenylsuccinimide in Mengen von 0,25 bis 8 Gewichtsprozent zugesetzt.
Als Schmierölzusätze werden die Alkenylsuccinimide in Mengen von 0,25 bis 8 Gewichtsprozent zugesetzt.
Die Metalldithiophosphate werden in Mengen von
5 Millimol bis 35 Millimol je Kilogramm (d. h. 5 bis
ίο 35mM'kg), vorzugsweise von 10 bis 18mM.kg, des
fertigen Produktes, bezogen auf den Metallgehalt zugesetzt, also von 0,2 bis 1,45" u des Produktes.
Die Succinimide und die Metalldithiophosphate werden in einem gewissen relativen Molverhältnis
verwendet. Das Molverhältnis von Suceinimid zu Dithiophosphat liegt zwischen etwa 1 : 10 und 6 : 1
und insbesondere zwischen 1 : 1 und 3:1. Das bedeutet, daß das Succinimid-Dithiophosphat-Molverhältnis
einen Wert von 0,05 bis 10, vorzugsweise 0,1 bis 6 und insbesondere von 0,5 bis 3,0 aufweist.
Die Herstellung der N-Dialkylaminoalkylmonoalkenylsuccinimide
wird in den folgenden Beispielen erläutert: diese Herstellung wird hier nicht unter
Schutz gestellt.
Beispiel 1
Herstellung von Polybutenylbernsteinsäureanhydrid
Herstellung von Polybutenylbernsteinsäureanhydrid
Ein Gemisch von 1000g (1 Mol) eines Polybutens mit einem Molekulargewicht von etwa 1000 und 98 g
(1 Mol) Maleinsäureanhydrid wird 24 Stunden unter Rühren in einer Stickstoffatmosphäre auf 210 C
erhitzt. Das Reaktionsgemisch wird auf 65 C abgekühlt, 700 cm3 Hexan werden zugegeben, und das
Gemisch im Vakuum filtriert. Nachdem das Hexan durch Vakuumdestillation aus dem Filtrat entfernt
ist. hält man das Produkt 1 Stunde bei einem absoluten Druck von 10 mm Hg auf 177 C, um Spuren
von Maleinsäureanhydrid zu entfernen. Das rohe Polybutenylbernsteinsäureanhydrid weist eine Verseifungszahl
von 79 auf.
Herstellung von N-Dimethylaminopropylpolybutenylsuccinimid
Ein Gemisch von 21,3 g (0,21 Mol) Dimethylaminopropylamin
und 150 g <(),09 Mol) Polybutenylbernsteinsäureanhydrid
des Beispiels 1 wird unter Rühren in einer Stickstoffatmosphäre gemischt und das Gemisch 1 Stunde auf 260 C erhitzt. Darauf
wird der absolute Druck 30 Minuten lang bei gleichbleibender Temperatur auf etwa 200 mm Hg herabgesetzt,
um die Entfernung des Wassers und überschüssigen Amins zu erleichtern. Das Reaktionsgemisch läßt man dann bei diesem verringerten Druck
auf Raumtemperatur abkühlen. Das Reaktionsprodukt enthält 1.7" 0 Stickstoff (theoretische Menge
1,8%). Die Identität des N-Dimethylaminopropylalkenylsuccinimids
wurde mittels Infrarotspektroskopie bewiesen.
In der Tabelle 1 sind weitere Daten hinsichtlich der
Herstellung der N-Dialkylaminoalkylalkenylsuccinimide
zusammengestellt. Das Polyamin ist Dimethylaminopropylamin, und der Alkenylrest im Alkenylsuccinimid
ist ein Polybuten, dessen Molekulargewicht in Tabelle 1 angegeben ist.

Die Tabelle II zeigt die synergistische Wirkung, die
durch Kombination von Metalldithiophosphaten und N - Dialkylaminoalkylmonoalkenylsuccinimiden als
Schmierölzusätzen erreicht wird.
Als Succinimid wird ein N-Dimethylaminopropylalkenylsuccinimid
verwendet, dessen Alkenylrest ein Molekulargewicht von etwa 1000 aufweist und ein
Isobutenpolymeres ist.
Als Ditbiopbosphat wird ein Zinksalz eines gemischten
Dialkyldithiophosphats verwendet, dessen einer Alkylrest 4 Kohlenstoffatome und dessen anderer
Alkylrest 6 Kohlenstoffatome enthält.
Das Basisöl ist ein SAE-10-öl
Die Daten wurden unter Zugrundelegung der im Coordinating Research Council Handbook, vom
Januar 1946, im Anhang 1 beschriebenen Bedingungen in einem L-I-Test mit einem Raupenschleppermotor
erhalten.
Die KV-Zahl (Kolbenverfärbungszahl) bezieht sich auf die Geschwindigkeit, mit der sich der Kolben
verfärbt. Nach dem Motorentest wurden die drei Kolbenstege mit bloßem Auge geprüft. Ein vollständig
schwarzer Kolbensteg erhielt die KV-Zahl 800, ein gänzlich sauberer die KV-Zahl 0. Zwischen
vollständig schwarz und ganz sauber liegende Kolbenstege erhielten im Verhältnis zum Ausmaß und
Grad der Verschmutzung dazwischenliegende KV-Zahlen.

* Diese Ergebnisse wurden bei einem L-1-Versuch mit einem Raupenschleppermotor unter Zugrundelegung der MlL-L-2104-Bedingungen
erzielt. Unter den strengeren Bedingungen des Anhanges 1 würden diese KV-Zahlen erheblich höher liegen.
Die folgenden Tabellen, 111 und IV zeigen weitere Daten, durch die die synergistischen Wirkungen der
beschriebenen Succinimid - Dithiophosphat - Kombination hervorgehoben werden.
Die Basisöle und das Succinimid sind die gleichen wie in Tabelle II.
Das Dithiophosphat A ist ein Zinksalz eines gemischten Dialkyldithiophosphates, in dem der eine
Alkylrest 4 Kohlenstoffatome und der andere 5 Kohlenstoffatome enthält. Das Dithiophosphat B ist ein
Zinksalz eines Di-(alkylphenyl)-dithiopbosphats, in dem die Alkylreste Propylenpolymere mit durchschnittlich
12 bis 14 Kohlenstoffatomen sind.
Die Bewertung der Harzbildung auf dem Kolben gründet sich auf eine Untersuchung der Menge des
Harzes aut einem Kolben mit bloßem Auge, wobei »10« der Höchstwert für einen vollständig sauberen
Kolben und »0« der Wert eines überall mit schwarzem Harz bedeckten Kolbens darstellen. Der Wert für
die Harzbildung auf dem Kolben steht in Beziehung zur Fahrleistung des Kraftfahrzeugs. Dieser Fl-2-Test
wird wie folgt durchgeführt:
Ein 6-Zylinder-Chevrolet-Motor wird 40 Stunden
mit einer Geschwindigkeit von 2500 U/min betrieben. Dieser Test ist ausführlich in einem Bulletin des
Coordinating Research Council mit dem Titel »Research Technique for the Determination of the
Effects of Fuels and Lubricants on the Formation of Deposits During Moderat Temperature Operation«
(1948) beschrieben.
