Abstract
Thioäther von β-Dicarbonyl- bzw. β-Cyanocarbonylverbindungen der allgemeinen Formel I <IMAGE> eignen sich ausgezeichnet als Schmiermittelzusätze, insbesondere als "Extreme-Pressure"- und "Antiwear"-Additive sowie als Aktivatoren von Chlorparaffinen in Metallverarbeitungsölen. Bezüglich der Bedeutungen der Substituenten in der Formel I wird auf Anspruch 1 verwiesen.
Description
- Die vorliegende Erfindung betrifft die Verwendung von Thioäthern von ß-Dicarbonyl- bzw. β-Cyanocarbonylverbindungen zur Ausrüstung von Schmiermitteln einschliesslich Metallverarbeitungsölen.
- Es wurde gefunden, dass Thioäther von ß-Dicarbonyl- bzw. β-Cyanocarbonylverbindungen sich ausgezeichnet als Schmiermittelzusätze, insbesondere als "Extreme-Pressure"- und "Antiwear"-Additive, sowie als Aktivatoren (Boosters) von Chlorparaffinen in Metallverarbeitungsölen eignen.
- Aus der EP-OS 1 217 sind wohl bestimmte Thioäther als Schmiermittelzusätze bekannt. Es handelt sich dabei jedoch um β-substituierte Epithioverbindungen und deren Anlagerungsprodukte, die strukturell mit den erfindungsgemäss einzusetzenden Thioäthern nicht vergleichbar sind.
- Gegenstand vorliegender Erfindung sind dementsprechend Schmiermittel, die als Additiv eine Verbindung der Formel I
- Rl, R3 und R5 sind als C1-C12 Alkyl verzweigtes oder unverzweigtes Alkyl, wie z.B. Methyl, Aethyl, n-Propyl, Isopropyl, n-Butyl, tert.-Butyl, n-Pentyl, α-Methylpentyl, Hexyl, 2,4-Dimethylpentyl, Octyl, 6-Methylheptyl, Decyl, Dodecyl. R1 und R5 sind bevorzugt C1-C4 Alkyl, insbesondere Methyl. R3 ist bevorzugt Aethyl, tert.-Butyl, 1,1,3,3-Tetramethylbutyl oder 1,1,3,3,5,5-Hexamethylhexyl.
- R1 ist als unsubstituiertes C6-C10 Aryl z.B. Naphthyl oder insbesondere Phenyl.
- Als durch C1-C4 Alkyl substituiertes C6-C10 Aryl ist R1 z.B. ein-, zwei- oder dreimal, bevorzugt einmal in der o- oder insbesondere in der p-Stellung durch Methyl, Aethyl, n-Propyl, Isopropyl, n-Butyl, tert.-Butyl substituiertes Phenyl.
- Als durch C1-C4-Alkoxy substituiertes C6-C10Aryl ist R1 z.B. ein-, zwei- oder dreimal, bevorzugt einmal in der o- oder insbesondere in der p-Stellung durch Methoxy, Aethoxy, n-Propyloxy, Isopropyloxy, n-Butoxy oder tert.-Butoxy substituiertes Phenyl.
- Als durch Halogen substituiertes C6-C10 Aryl ist R1 z.B. ein-, zwei-oder dreimal, bevorzugt einmal, in der o- oder insbesondere in der p-Stellung durch Jod, Brom oder insbesondere Chlor substituiertes Phenyl.
- Hervorzuheben sind Schmiermittel, die als Additiv eine Verbindung der Formel I enthalten, worin R1 C1-C4 Alkyl, unsubstituiertes oder durch C1-C4 Alkyl, C1-C4 Alkox oder Halogen substituiertes Phenyl oder eine Gruppe -OR3 ist, R eine Gruppe -C(O)R4 ist, R3 Aethyl, tert.-Butyl, 1,1,3,3-Tetramethylbutyl oder 1,1,3,3,5,5-Hexamethylhexyl bedeutet und R4 R1 oder eine Gruppe -O-CH2CH2-S-R3 ist, wobei R3 die in dieser Bevorzugung bereits angegebene Bedeutung hat.
- Bevorzugt sind Schmiermittel, die als Additiv eine Verbindung der Formel 1 enthalten, worin R1 Methyl oder Phenyl und R2 eine Gruppe -C(0)-OC2H5 oder -C(O)-OCH2CH2-S-C2H5 bedeutet.
- Die erfindungsgemäss zu verwendenden Thioäther der Formel I sind an sich bekannte Verbindungen. Sollten einige von ihnen noch neu sein, so können sie in Analogie zu bekannten Verfahren hergestellt werden, z.B. durch direkte Einwirkung von SC12 auf β-Dicarbonylverbindungen der Formel
- worin R1 und R2 die oben angegebene Bedeutung haben, etwa gemäss S.K. Gupta, J.Org.Chem.39, 1944 (1974) oder A. Angeli, F. Magnani, Gazz. 24, 342/364 (1894). Die Umsetzung von metallierten (z.B. mit Natrium) β-Cyanocarbonylverbindungen mit SCl2 stellt eine andere Variante dar. Schliesslich können auch 2-Chlor-ß-ketocarbonsäureester bzw. 3-Chlor-ß-ketocarbonsäureester mit H2S in Gegenwart von Chlorwasserstoffakzeptoren (NaOH, tertiäre Amine) in den erfindungsgemässen Verbindungen überführt werden.
- Die Verbindungen der Formel I wirken in Schmiermitteln schon in sehr geringen Mengen insbesondere als "Extreme Pressure"- und "Antiwear"-Additive sowie als Aktivatoren (Booster) von Chlorparaffinen in Metallverarbeitungsölen. So zeigen mineralische und synthetische Schmieröle, sowie deren Gemische, welche 0,001 bis 5 Gew.%, bezogen auf das Schmiermittel, und vorzugsweise 0,2-3 Gew.Z einer Verbindung der Formel I oder eines Gemisches solcher Verbindungen enthalten, ausgezeichnete Schmiereigenschaften, welche vor allem in stark reduzierten Abnutzungserscheinungen der zu schmierenden Reibpartner deutlich werden.
- Die in Frage kommenden Schmiermittel sind dem Fachmann geläufig und z.B. im "Schmiermittel-Taschenbuch" (Hüttig Verlag, Heidelberg, (1974) beschrieben. Besonders geeignet sind Mineralöle. Für die Metallverarbeitung besonders geeignete Systeme ("cutting fluids") sind z.B. in J.O. Cookson, An introduction to cutting fluids, TRIBOLOGY INTERNATIONAL (february 1977), SS.5-11, beschrieben.
- Die Schmierölformulierung kann zusätzlich noch andere Additive enthalten, die zugegeben werden, um gewisse Gebrauchs-Eigenschaften zu verbessern, wie Antioxidantien, Metallpassivatoren, Rostinhibitoren, Viskositätsindex-Verbesserer, Stockpunkterniedriger, Dispergiermittel/ Tenside und andere Verschleissschutz-Additive.

- Als Basisöl wird ein 150 VG32 Oel, enthaltend 5,0 Gew.% eines handelsüblichen chlorierten Paraffinkohlenwasserstoffs mit 50% Chlorgehalt, 1,0 Gew.% eines Verschleissschutz-Additivs des Triarylphosphat-Typs und 0,5 Gew.% N-Oleylsarcosin (Rost-Inhibitor), bezogen auf die gesamte Oel-Formulierung, verwendet.
- Die Ergebnisse sind in nachfolgender Tabelle angegeben.
- Beispiel 2: Es wird wie in Beispiel 1 vorgegangen mit dem Unterschied, dass als Basisöl ein 150 VG 100 Oel ohne Costabilisatoren verwendet wird. Die Ergebnisse sind in nachfolgender Tabelle II angegeben.
- Die verschleisshemmende Wirkung der erfindungsgemässen Schmiermittelzusammensetzung wird mit einer konventionellen Schmierstoff-Messmaschine bestimmt (H. Reichert, Maschinen- und Apparatebau). Ein Testzylinder von 2 cm Länge und 1 cm Durchmesser wird mit einer Kraft p an ein rotierendes Schleifrad gespresst, das mit konstanter Gleitgeschwindigkeit von 1,7 m/sec (900 U/min) in einem Oelbad dreht. Testkriterium ist die sich dabei ausbildende Verschleisskalotte als Funktion des Reibungswegs.
- Rad und Prüfkörper werden im Ultraschall in Siedegrenzbenzin und Aceton gereinigt. Anschliessend wird das Rad viermal mit reinem Basisöl eingefahren (Reibweg 100 m). Mit diesem definiert aufgerauhten Schleifring wird unter Standardbedingungen (100 m Reibweg, p = 14,7 N) mit reinem Basisöl eine Verschleisskalotte von 36-40 mm2 erhalten. Vor dem eigentlichen Test wird dieser Wert jeweils viermal kontrolliert.
- Die zu testende Schmiermittelzusammensetzung (Basisformulierung und Additiv) wird unter Standardbedingungen (100 m Reibweg, p = 14,7 N) geprüft. Bei wirksamer Zusammensetzung tritt eine markante Verminderung der Verschleisskalotte ein.
- Die Basisformulierung besteht aus einem 150VG32 Oel als Basisöl, 5,0 Gew.% eines handelsüblichen chlorierten Paraffinkohlenwasserstoffes mit 50 % Chlorgehalt, 1,0 Gew.Z eines Verschleissschutz-Additivs des Triarylphosphat Typs und 0,5 Gew.% N-Oleylsarcosin (Rost-Inhibitor), bezogen auf die gesamte Oel-Formulierung .
- Die Ergebnisse sind in nachfolgender Tabelle angegeben:
