Verbindungen organischer Dithiophosphorsäuren, insbesondere Zinkdithiophosphate, sind als Schmierölzusätze

Aufgabe der Erfindung ist es, noch wirksamere Schmierölzusätze bzw. diese Zusätze enthaltende
Schmieröle zur Verfugung zu stellen.
Gegenstand der Erfindung sind Schmieröle, die gekennzeichnet sind durch e.nen Gehalt an einem

mindestens 7,6 aliphatischen C-Atomen im Molekül und der allgemeinen Formel

Beispiele der Reste R sind Methyl-, Äthyl-, Isopropyl-,
Isobutyl-, η-Butyl-, sek.-Butyl-, n-Hexyl-, Heptyl-, 2-Äthylhexyl-, Diisobutyl-, Isooctyl-, Behenyl-,
Decyl-, Dodecyl-, Octadecyl-, Eikosyl-, Butylphenyl-,

Tetradecyl-, Cyclohexyl-, Phenyl-, Naphthenyl-, 2-Methylcyclohexyl- und Benzylreste. Alkylreste mit
etwa 3 bis etwa 30 Kohlenstoffatomen sind besonders bevorzugt.
Verfahren zur Herstellung der di-veresterten Phosphorsäuren
und deren Thioanalogen sind bekannt.
Die O,O'-di-veresterten Dithiophosphorsäuren. d. h.
die organischen Phosphorsäuren mit der Strukturformel
R—O—P—S—H
können hergestellt werden, indem man Phosphorpentasulfid
mit einem Alkohol oder Phenol umsetzt. Die Umsetzung erfolgt mit 4 Mol des Alkohol oder
Phenols je Mol Phosphorpentasulfid and kann innerhalb des Temperaturbereichs von etwa 50 bis
200 C durchgeführt werden. So erfolgt die Herstellung von "o.O'-Di-n-hexyldithiophosphorsäure
durch" Umsetzung des Phosphorpentasulfids mit 4 Mol n-Hexylafkohol bei etwa IOD C in etwa
2 Stunden. Es wird Schwefelwasserstoff freigesetzt, und der Rückstand ist die definierte Saure.
Die in den Schmierölen der Erfindung enthaltenen Molybdänsalze lassen sich auf einfache Weise durch
Umsetzen eines Alkalimetallsalzes (beispielsweise eines Natrium- oder Kaliumsalzes) der organischen
Phosphorsäure mit einem Alkali- oder Ammoniummolybdat herstellen. Die Umsetzung ist meist exotherm
und findet bereits beim einfachen Mischen der Reaktionsteilnehmer bei gewöhnlichen Temperaturen,
beispielsweise bei Raumtemperaturen, statt. Das Produkt kann aus dem Reaktionsgemisch
durch Ansäuern des Gemisches z. B. mit Salzsäure, Essigsäure oder Schwefelsäure gewonnen werden.
Die Reaktion wird vorzugsweise in Gegenwart eines Lösungsmittels, wie Benzol, Naphtha. Mineralöl,
Tetrachlorkohlenstoff, Chloroform, Aceton, Äther oder Nitrobenzol, durchgeführt.
Man kann auch die organische Phosphorsäure direkt mit einem Alkalimolybdat oder -tliiomolybdat
reagieren lassen. Auch diese Umsetzung kann in ähnlicher Weise bei normalen Temperaturen, wie
Raumtemperatur, durchgeführt werden. Ein weiteres geeignetes Verfahren ist die Umsetzung der organischen
Phosphorsäure mit einem geeigneten Molybdäntrisulfd oder -oxyd. Diese Reaktion scheint
durch Wasser oder durch einen niederen Alkohol, wie Methanol oder Äthanol, gefördert zu werden.
Die Temperatur, bei der die Reaktion ausgeführt wird, bewegt sich gewöhnlich im Bereich zwischen
etwa Raumtemperatur und 1000C. Es sei bemerkt, daß das Produkt der oben veranschaulichten Verfahren
entweder das tetraphosphorylsubstituierte Molybdänoxyd oder -sulfid sein kann, je nachdem,
ob der verwendete Molybdänreaktionsteilnehmer ein Molybdänoxyd oder -sulfid bzw. ein Molybdat oder
Thiomolybdat ist. Das Produkt kann ein Gemisch aus Mono- oder Di- oder Trioxyden oder -sulfiden
der Molybdänsalze der Phosphorsäuren sein.
Nachstehend wird die Herstellung einiger als Zusatzstoffe für Schmieröle der Erfindung geeigneter
Molybdänsalze beschrieben.

- di - (p - tert. - pentylphenyl) - phosphordithio)-molybdänoxyd mit einem Phosphorgehalt von 7.1%
und einem Molybdängehalt von 4,4%.
Die erfindungsgemäß verwendeten Molybdänsalze der organischen Phosphorsäuren sind wirksame
Reinigungsmittel (Detergents), Korrosionsinhibitoren, Schaumbremsen, Oxydationsinhibitoren und verschleißhemmende
Mittel. Sie lassen sich außer Schmierölen auch Schmierfette und Kraftübertragungstlüssigkeiten
einverleiben. Im allgemeinen sind Molybdänsalze mit einem Gehalt von mindestens etwa 7,6 aliphatischen Kohlenstoffatomen je
Phosphoratom in Kohlenwasserstoffölen löslich. Sie können z. B. aus Säuren des Phosphors hergestellt
werden, die man durch Umsetzen von Phosphorpentasulfid mit einem Alkoholgemisch erhält, in dem
ein höhermolekularer Alkohol (d. h. ein Alkohol mit mindestens 5 aliphatischen Kohlenstoffatomen) und
ein niedermolekularer Alkohol (d. h. ein Alkohol mit weniger als 5 aliphatischen Kohlenstoffatomen) in
einem solchen Mengenverhältnis anwesend sind, daß eine Phosphorsäure entsteht, die mindestens 7,6 aliphatische
Kohlenstoffatome je Phosphoratom ent-
hält. Beispiele solcher Säuren sind die Reaktionsprodukte von Phosphorpentasulfid mit einem Gemisch
aus 70 Molprozent Cyclohexylalkohol und 30 Molprozent Isopropylalkohol, mit einem Gemisch
aus 80 Molprozent n-Pentylalkohol und 20 Molprozent
n-Butylalkohol und mit einem Gemisch aus 40 Molprozent Ociylalkohol, 20 Molprozent Decyclalkohol
und 40 Molprozent Äthylalkohol. Es können auch öllösliche Molybdänsalze verwendet werden, die
aus Säuregemischen hergestellt sind, die durchschnittlich mindestens 7,6 sliphatische Kohlenstoffatome
je Phosphoratom enthalten, also aus Säuren mit mehr und Säuren mit weniger als 7,6 aliphatischen
Kohlenstoffatomen je Phosphoratom zusammengesetzt sein können. Ein Beispiel eines solchen
Säuregemisches ist ein Gemisch aus 70 Molprozent Ο,Ο'-Dihexyldithiophosphorsäure und 30 Molprozent
O.O'-Di-propyldithiophosphorsäure. Zu den vorstehenden Säuren und Säuregemischen zählen
diejenigen, die in der USA.-Patentschrift 2 838 555 beschrieben sind.
Die erfindungsgemäß verwendeten öllöslichen Molybdänsalze organischer Phosphorsäuren sind
besonders wirksame verschleißmindernde, oxydations- und korrosionsinhibierende Schmierölzusätze.
Sie entfalten ihre Wirksamkeit in Mineralölen sowie synthetischen, tierischen und pflanzlichen ölen. In
der Regel sind als Basisöle öle mit einer Viskosität von etwa 40 SUS bei 37,80C bis etwa 200 SUS bei
98,9 "C bevorzugt. Der Molybdänsalzgehalt der Schmieröle der Erfindung liegt in der Regel zwischen
etwa 0,001 und etwa 10 Gewichtsprozent. Vorzugsweise liegt der Molybdänsalzgehalt zwischen etwa
0,01 und etwa 5 Gewichtsprozent bei Molorschmierölen und zwischen etwa 0,5 und etwa 10% bei
Getriebeschmi rölen.
Die Leistungsfähigkeit der erfindungsgemäßen Schmieröle ist aus den Ergebnissen eines modifizierten
CRC-L-4-545-Motortests zu ersehen. (Die Modifikation besteht darin, daß man die Testzeit
von 36 auf 72 Stunden ausdehnt und so den Test erschwert.) Der Test wird in einem 6-Zylinder-Benzinmotor
unter folgenden Bedingungen ausgeführt: Drehzahl 3150 U/min; Belastung 30 Bremspferdestärken;
Kühlwassertemperatur 93 C am Auslaß und 880C am Einlab; öltemperatur in der ölwanne
129°C; Luft-Kraftstoff-Verhältnis 14,5 : 1. Das geprüfte Schmieröl wird bewertet nach dem
Gewichtsverlust der Lager, der Kolbenreinheit und nach der Gesamtv;rlackung und den Schlammablagerungen
auf den verschiedenen Teilen des Motors. Bei diesem Test ergibt ein Mineralschmieröl SAE 30
mit einem Gehalt von 0,89 Gewichtsprozent Tetra-(O,O'
- dinonylphosphordithio) - molybdänoxyd (Molybdänsalz 5) eine Kolbenreinheit von 8 (10 ist vollkommen
sauber) und eine Gesamtverlatkungs- und
Schlammablagerungsbewertung von 85,5 (100 ist vollkommen sauber).
Die überlegenen Eigenschaften der Schmieröle der Erfindung im Vergleich zu bekannten Schmierölen,
die an Stelle der in den erfindungsgemäßen Schmierölen enthaltenen Mo'.ybdänsalze Zinkdithiophosphate
enthalten, ergibt sich aus den nachstehenden Vergleichsversuchen.
Als erfindungsgemäßv.··/ Zusatzstoff wird dabei
jeweils ein Molybdänsalz der O,O'-Di-(n-decyl)-dithiophosphorsäure
als Zusatzstoff nach dem Stand Her Technik das Zinksalz dieser Säure verwendet.

Durch 300 ml eines Schmieröls, das den Zusatzstoff enthält, dessen Wirksamkeit geprüft werden soll, wird bei 1490C in Anwesenheit einer Probe des Lagermetalls 166 Stunden Luft mit einer Geschwindigkeit von 28,3 l/Stunde geblasen. Am Ende des Versuchs werden jeweils der Gewichtsverlust des
3S Lagermetalls und die Viskositätsernöhuug des
Schmieröls in Prozent bestimmt. Die Wirksamkeit des Zusatzstoffes ist umgekehrt proportional dem
Gewichtsverlust und der Viskositätserhöhung.
Bei diesem Test werden SAE-30-Motorschmieröle verwendet, die 2 Gewichtsprozent eines Umsetzungsproduktes aus einer Polyisobutenylbernsteinsäure
und einem Polyäthylenpolyamin sowie jeweils so viel Molybdän- bzw. Zinkdithiophosphat enthalten, daß
der Phosphorgehalt 0,015 Gewichtsprozent beträgt.

Vergleichsversuch 3
Bestimmung der Oxydationsinhibitorwirkung
Bestimmung der Oxydationsinhibitorwirkung
Der Test wird analog Vergleichsversuch 2 durchgeführt mit einer geringfügig anderen Probengröße
und Luftgeschwindigkeit. Der wesentliche Unterschied besteht darin, daß der Oxydationskatalysator
aus Eisen, Kupfer und Blei besteht. Die Versuchsdaucr beträgt mindestens 64 Stunden. Der Versuch wird
darüber hinaus fortgesetzt, bis Schlammbildung erfolgt. Bewertet werden die Viskositätserhöhung in
Prozent und die Anzahl der Stunden bis zum Beginn der Schlammbildung.
Geprüft werden vier Schmieröle 1 a, 1 b. 2 a und 2b (la und 2a = erfindungsgemäße Schmieröle;
1 b und 2b = Schmieröle nach dem Stand der Technik), von denen die Schmieröle 1 a und 1 b
außer dem Zusatzstoff, dessen Wirkung gcpiüft werden soll, 1 Gewichtsprozent eines basischen
Bariumerdölsulfonats enthalten. Das Basisöl der Schmieröle 2 a und 2 b entspricht demjenigen der
im Vergleichsversuch 2 untersuchten Schmieröle.
Die Schmieröle enthalten jeweils so viel auf seine Wirksamkeit zu untersuchenden Zusatzstoff, daß ihr
Phosphorgehalt 0,05% beträgt.
