Die Schmierölzusatzstoffe können eingeteilt werden in eine Gruppe aus Substanzen, welche Metallatome
enthalten, beispielsweise Metallseifen von öllöslichen organischen Säuren, und in eine Gruppe von Verbindungen,
die keine Metallatome enthalten. Diese zuletzt genannte Gruppe von Zusatzstoffen weist statt der
Metallatome eine polare organische Gruppe im Molekül auf, der sie die Eigenschaft, als Zusatzstoffe zu
wirken, verdankt. Vertreter dieses speziellen Typs von Zusatzstoffen sind z. B. tertiäre Amine mit einer
einzigen langkettigen Alkylgruppe von 10 bis 24 Kohlenstoffatomen und mit 2 kurzkettigen Alkylgruppen,
welche in der US-Patentschrift 24 76 271 beschrieben werden und welche man als Antioxydationsmittel
einsetzt.
Ferner sind Schmierölzusatzstoffe mit reinigender Wirkung bekannt, welche sich von einem Monoalkenylbernsteinsäureimid
ableiten, dessen Stickstoffatom mit dem Rest von Tetraäthylenpentamin verknüpft ist Auch
ist empfohlen worden, derartige Kondensationsprodukte noch mit einer Vorverbindung, wie Bortrifluorid oder
Borsäure, umzusetzen. Infolge des Einbaues des Boratoms soll die Schlammbildung herabgesetzt werden.
Außerdem sind für die Verwendung als Textilhilfsmittel
geeignete, wasserlösliche oder in Wasser leicht verteilbare bzw. dispergierbare stickstoffhaltige Kondensationsprodukte
beschrieben worden, die bei der Umsetzung von höhermolekularen, halogenhaltigen,
aliphatischen, cycloaliphatischen oder naphthenischen Verbindungen mit solchen Mengen an Polyalkylenpolyaminen
entstehen, daß auf jedes bei der Kondensation abzuspaltende Halogenatom mindestens 2 Moleküle
Polyalkylenpolyamin kommen.
Die Erfindung bezieht sich nun auf die Herstellung neuer Verbindungen, welche einem Schmieröl reinigende
Eigenschaften verleihen und außerdem in unter niedriger Belastung laufenden Motoren die Schlammbildung
in sehr wirksamer Weise verhindern und ein besseres Verhalten als im Handel erhältliche vergleichbare
Zusatzstoffe zeigen.
Das erfindungsgemäße Verfahren zur Herstellung von alkyl- oder alkenylsubstituierten aliphatischen
mehrwertigen Aminen durch Umsetzung von Alkyl- oder Alkenylhalogeniden mit mehrwertigen aliphatischen
Aminen, ist dadurch gekennzeichnet, daß Alkyl- oder Alkenylhalogenide mit mindestens 50 Kohlenstoffatomen
eingesetzt werden, deren Alkyl- oder Alkenylgruppe sich von Olefinpolymerisaten oder -mischpolymerisaten
ableitet.
Die neuen Zusatzstoffe gemäß der Erfindung verdanken ihre reinigenden Eigenschaften zum Teil der
polaren Gruppe und zum Teil der langkettigen Alkyl- oder Alkenylgruppe, welche eine räumliche Abstoßung
anderer Schmutzteilchen bewirkt, nachdem ein Molekül des Zusatzstoffes mit der polaren Gruppe von einem
Schmutzteilchen oder dergleichen adsorbiert worden ist.
Die Alkyl- oder Alkenylgruppe leitet sich von geradkettigen oder verzweigtkettigen Olefinpolymerisaten
oder -mischpolymerisaten ab.
Vorzugsweise liegt ein mehrwertiges aliphatisches Amin zugrunde, welches wenigstens 3 Stickstoffatome
enthält, insbesondere ein entsprechendes Polyamin aus der Reihe der Polyäthylenpolyamine.
Beispiele für im Rahmen der Erfindung hergestellte' Alkenylpolyäthylenpolyamine sind Polyisobtrtenyldiäthylentriamin,
Polyisobutenyltriäthylentetramin und Polyisobutenyltetraäthylenpentamin, wobei die Polyisobutenylgruppen
80 bis 120 Kohlenstoff atome enthalten.
Bei der Bildung der neuen substituierten mehrwertigen Amine wird gleichzeitig der entsprechende
Halogenwasserstoff freigesetzt, der z. B. in Form eines Salzes mit dem überschüssigen, als Ausgangsmaterial
eingesetzten mehrwertigem Amin entfernt wird. Während dieser Umsetzung zwischen einem Alkyl- oder
Alkenylhalogenid und diesen stark basischen Aminen kann als Nebenreaktion eine Dehalogenierung des
Alkyl- oder Alkenylhalogenids eintreten, so daß als Nebenprodukte Kohlenwasserstoffe gebildet werden.
Die Entfernung dieser Kohlenwasserstoffe aus dem Endprodukt ist aber nicht unbedingt erforderlich.
Gemäß einer bevorzugten Ausführungsform für die Herstellung der neuen Amine geht man von einem
Alken mit einer endständigen Doppelbindung aus, dessen Kohlenstoffatom im beta-Stellung eine Methylgruppe
trägt Bei der Chlorierung mit der theoretisch benötigten Menge an Chlor bildet sich ein alpha-Polyisobutylallylchlorid
und beta-Polyisobutylmethallylchlorid,
während gleichzeitig HCl abgespalten wird. Außerdem entsteht infolge von Nebenreaktionen eine
gewisse Menge der entsprechenden Dichlorverbindung. Mit dem so erhaltenen Chlorierungsprodukt wird dann
das Polyamin zu dem entsprechenden Alkenylpolyamin umgesetzt. Als Ausgangsmaterial dient beispielsweise
Polyisobutylen, welches in einem inerten Lösungsmittel bei Zimmertemperatur mit der theoretischen Menge an
Chlor behandelt wird, worauf das entstehende Polyisobutenylchlorid mit Tetraäthylenpentamin zu Polyisobutenyltetraäthylenpentamin
bzw. zu Dipolyisobutenyltetraäthylenpentamin umgesetzt wird.
Die erfindungsgemäß hergestellten Amine stellen ausgezeichnete Dispergiermittel dar und sie verleihen
den Schmierölen, denen sie einverleibt werden, sehr befriedigende Eigenschaften. Als Schmierölbasis können
Mineralschmieröle der verschiedensten Viskositätsgrade sowie synthetische Schmieröle oder ein mit einem
fetten öl verschnittenes Schmieröl eingesetzt werden. Der Zusatzstoff kann dem Schmieröl als solcher oder in
Form eines Konzentrates beigemischt werden, welches man beispielsweise erhält, indem man den Zusatzstoff
mit einer kleinen Menge öl vermischt Die Konzentration des Zusatzstoffes in dem öl kann innerhalb eines
weiten Bereiches variieren. Im allgemeinen wird die gewünschte reinigende Wirkung bereits erzielt wenn
man dem Schmieröl den Zusatzstoff in Mengen zwischen 0,1 und 10 Gew.-% zumischt doch kann es in
besonderen Fällen auch erforderlich sein, größere Mengen als die vorstehend erwähnten Konzentrationen
anzuwenden, beispielsweise, wenn das Schmieröl in Dieselmotoren eingesetzt werden soll, welche zu einer
starken Verschmutzung neigen.
Die erfindungsgemäß hergestellten Amine können auch in Kombination mit anderen bekannten Zusatzstoffen
angewendet werden, z. B. mit Antioxydationsmitteln, Reinigungsmitteln, Verbesserungsmitteln für
den Viskositätsindex, Antikorrosionsmitteln, Antischaummitteln, Mitteln zur Verbesserung der Schmierwirkung
und mit Substanzen, wie sie üblicherweise Schmierölen zugesetzt werden.
Die Erfindung wird durch das nachstehende Beispiel näher erläutert
Ausführungsbeispiel Herstellung von Polyisobutenyltetraäthylenpentamin
a) Ein Polyisobutylen mit einem Molgewicht von 1250 wurde in einer Konzentration von 40 Gew.-% in
Tetrachlorkohlenstoff aufgelöst Nach dem Zusatz eines Jodkristalls wurde Chlor bei Zimmertemperatur so
lange in die Lösung eingeleitet bis die Farbe derselben verblaßte. Anschließend wurde das Lösungsmittel im
Vakuum verdampft, wobei gleichzeitig das gebildete gasförmige HCl entfernt wurde. Der verbleibende
Rückstand enthielt noch 4,2 Gew.-% Chlor.
b) Das so erhaltene Polyisobutenylchlorid wurde 6 Stunden lang unter Rühren mit der vierfachen Menge
Tetraäthylenpentamin auf 1800C erhitzt Nach dem Abkühlen wurde das Reaktionsprodukt in Pentan
aufgenommen und bis zur Chlorfreiheit mit Wasser gewaschen. Anschließend wurde das Lösungsmittel
abgedampft. Der verbleibende Rückstand enthielt 2,5 Gew.-% Stickstoff und 0,23 Gew.-% Chlor.
Dieser Zusatzstoff wurde in einem Einzylinder Gardner-Dieselmotor und in einem Einzylinder Petter-Benzinmotor
geprüft Der Zusatzstoff lag in der fertigen Schmieröllösung in einer Konzentration von
1,5 Gew.-°/o vor. Als Schmierölbasis wurde ein lösungsmittelraffiniertes, paraffinisches Schmieröldestillat verwendet.
Die Viskosität des Basisöls betrug bei dem Petter-Test 7,2 oSt (98,9°) und bei dem Gardner-Test
11,5 cSt (98,9°).

Produkten vergleichbarer Art zu belegen, wird der nachstehende Vergleichsversuch durchgeführt.
Vergleichsversuch
Ein Polyisobutylen mit einem Molgewicht von 1240 wurde gemäß der Erfindung in einer Konzentration von
30 Gewichtsprozent in Iso-oktan bei 200C während
20 Minuten mit Chlor behandelt Das Lösungsmittel wurde anschließend verdampft, und das Polyisobutylenchlorid
(2,93 Gewichtsprozent Cl) wurde in siedendem Toluol und in Gegenwart von K2CO3 als
HCl-Akzeptor mit Tetraäthylenpentamin (Molverhältnis 1:1) zu Polyisobutenyltetraäthylenpentamin (2,84%
N, 0,44% Cl, Molgewicht 1570) umgesetzt (Additiv A). Auf diese Weise wurden etwa 50 kg Additiv A im
halbtechnischen Maßstab hergestellt
Das erfindungsgemäße Additiv A und ein handelsübliches Imid von Polyisobutylenbernsteinsäure und Tetraäthylenpentamin
(Additiv B) wurden in einem Fiat-Benzinmotor in Form einer Lösung von 1,5 Gewichtsprozent
Zusatzstoff in einem Mineralschmieröl mit einem hohen Viskositätsindex (HVI) geprüft.
Der wassergekühlte Vierzylinder-Viertakt-Benzinmotor weist eine Zylinderbohrung von 77 mm, einen
Hub von 79,5 mm, einen Hubraum von 1481 cm3, ein
Kompressionsverhältnis von 8,8 :1 und eine abgegebene Leistung von 34,2 PS bei 3600 Umdrehungen/Min,
auf. Die Testdauer beträgt 35 und 70 Stunden. Als Kraftstoff wird ein handelsübliches Premiumbenzin
verwendet, das Bleitetraäthyl enthält. Das Zylinderkühlwasser hat eine Temperatur von 900C.
Es wird der Grad der Kolbenverschmutzung bestimmt. Die Ergebnisse dieser Motortests sind zusammen
mit den für ein Basisöl ohne Zusatzstoff erhaltenen Ergebnisse in der folgenden Tabelle angegeben:
