Description
Die vorliegende Erfindung betrifft Schmiermittelzusammensetzungen, enthaltend Dithiophosphate. The present invention relates to lubricant compositions containing dithiophosphates.
Mineralischen und synthetischen Schmierstoffen werden im allgemeinen verschiedene Zusatzstoffe zur Verbesserung ihrer Gebrauchseigenschaften beigegeben. Insbesondere besteht ein Bedarf an Additiven, welche die zu schmierenden Vorrichtungen vor Reibungsabnutzung schützen sollen. An solche Verschleissinhibitoren wird die Anforderung gestellt, dass sie das Lasttragevermögen des Schmierstoffs erhöhen und nicht korrodierend auf die zu schützenden Metallteile wirken. Aus dem SU-Patent 295 791 ist bekannt, N-mono-substituierte Dithiophosphatessigsäureamid-Schmierölzusätze zu verwenden. N-Disubstituierte Dithiophosphatessigsäureamide sind als Pestizide aus dem GB-Patent 1 255 946 bekannt. Various additives are generally added to mineral and synthetic lubricants to improve their performance properties. In particular, there is a need for additives which are intended to protect the devices to be lubricated from frictional wear. Such wear inhibitors are required to increase the load-bearing capacity of the lubricant and not to have a corrosive effect on the metal parts to be protected. From SU patent 295 791 it is known to use N-mono-substituted dithiophosphate acetic acid amide lubricating oil additives. N-disubstituted dithiophosphate acetic amides are known as pesticides from GB Patent 1,255,946.
Es wurde nun überraschend gefunden, dass die Dithiophosphate der Formel I den bekannten Hochdruck-Zusätzen für Schmiermittel überlegen sind, insbesondere hinsichtlich Aschefreiheit, Thermostabilität, Nicht-Korrosivität gegenüber Eisen und Buntmetallen und Hydrolysebeständigkeit. It has now surprisingly been found that the dithiophosphates of the formula I are superior to the known high-pressure additives for lubricants, in particular with regard to freedom from ash, thermostability, non-corrosivity to iron and non-ferrous metals and resistance to hydrolysis.
Die Erfindung betrifft demgemäss Schmiermittelzusammensetzungen, enthaltend eine Verbindung der Formel I The invention accordingly relates to lubricant compositions containing a compound of the formula I.

Besonders geeignet sich Schmiermittelzusammensetzungen, enthaltend eine Verbindung der Formel I, worin Ri gleich R2 und C3-C8 Alkyl ist, oder Ri und R2 zusammen C2-C8 Alkylen sind, und X -NR3R4 oder -OH • NR3R4R5 ist, worin R3, R4 und Rs unabhängig voneinander Wasserstoff oder Ci-Cis Alkyl sind. Particularly suitable are lubricant compositions comprising a compound of the formula I in which Ri is R2 and C3-C8 alkyl, or Ri and R2 together are C2-C8 alkylene, and X is -NR3R4 or -OH • NR3R4R5, in which R3, R4 and Rs are independently hydrogen or Ci-Cis alkyl.
Bevorzugt sind vor allem Schmiermittelzusammensetzungen, enthaltend eine Verbindung der Formel I, worin Ri gleich R2 und C3-Cs-Alkyl ist, oder Ri und R2 zusammen C2-C8 Alkylen sind, X -NR3R4 ist, und R3 gleich R4 und Ci-Cis Alkyl ist. Particularly preferred are lubricant compositions containing a compound of the formula I in which Ri is R2 and C3-Cs-alkyl, or Ri and R2 together are C2-C8 alkylene, X is -NR3R4, and R3 is R4 and Ci-Cis alkyl is.
Bevorzugt sind vor allem Schmiermittelzusammensetzungen, die eine der in den Beispielen genannten Verbindungen der Formel I enthalten. Lubricant compositions which contain one of the compounds of the formula I mentioned in the examples are particularly preferred.
Die Herstellung der Verbindungen der Formel I erfolgt nach an sich bekannten Verfahren. Dabei geht man entweder gemäss dem GB-Patent 1 255 946 vor und erhält Verbindungen der Formel I mit X gleich -NR3R4, oder man setzt eine Säure (Ri0XR20)P(S)-S-CH2-C00H mit einem Amin NR3R4R5 um und erhält Verbindungen der Formel I mit X gleich -OH.NR3R4R5. The compounds of the formula I are prepared by processes known per se. The procedure is either according to GB patent 1 255 946 and compounds of the formula I with X equal to -NR3R4 are obtained, or an acid (Ri0XR20) P (S) -S-CH2-C00H is reacted with an amine NR3R4R5 and obtained Compounds of formula I with X equal -OH.NR3R4R5.
Die Verbindungen der Formel I wirken schon in sehr geringen Mengen als Hochdruck-Zusätze in Schmiermitteln. So zeigen mineralische und synthetische Schmieröle, sowie deren Gemische, welche mit 0,001 bis 5 Gew.-% bezogen auf das Schmiermittel, und vorzugsweise 0,02 bis 3% einer Verbindung der Formel I ausgestattet sind, ausgezeichnete Hochdruck-Schmiereigenschaften, welche durch stark reduzierte Abnutzungserscheinungen der zu schmierenden Reibpartner deutlich werden. Die in Frage kommenden Schmiermittel sind dem Fachmann geläufig und z. B. im «Schmiermittel Taschenbuch» (Hüthig Verlag, Heidelberg, 1974) beschrieben. Even in very small amounts, the compounds of the formula I act as high-pressure additives in lubricants. Mineral and synthetic lubricating oils and their mixtures, which are provided with 0.001 to 5% by weight, based on the lubricant, and preferably 0.02 to 3% of a compound of the formula I, show excellent high-pressure lubrication properties, which are reduced by greatly reduced Signs of wear of the friction partners to be lubricated become clear. The lubricants in question are familiar to the expert and z. B. in the "Lubricant paperback" (Hüthig Verlag, Heidelberg, 1974) described.
Die Schmierölformulierung kann zusätzlich noch andere Additive enthalten, die zugegeben werden, um gewisse Gebrauchs-Eigenschaften zu verbessern, wie Antioxidantien, Metallpassivatoren, Rostinhibitoren, Viskositätsindex-Verbesserer, Stockpunkterniedriger, Dispersants/Detergents und andere Verschleissschutz-Additive. The lubricating oil formulation can additionally contain other additives which are added to improve certain performance properties, such as antioxidants, metal passivators, rust inhibitors, viscosity index improvers, pour point depressants, dispersants / detergents and other wear protection additives.

Nach lOstündigem Rühren bei Raumtemperatur wird das Reaktionsgemisch mit 50 ml 6n Salzsäure angesäuert und mit 200 ml Toluol anschlies-25 send ausgezogen. Die Toluolphase wird zweimal mit Wasser gewaschen und anschliessend unter reduziertem Druck vollständig eingeengt. Man erhält so das 0,0-Di-isopropyl-S-carbo-xymethyl-dithiophosphat als ein hellgelbes öl. 80 g (0.31 mol) of potassium salt or 0.0-di-isopropyl-dithio-20 phosphoric acid are dissolved in 100 ml of water and while stirring with a solution of 36.1 g (0.31 mol) of sodium salt of chloroacetic acid in 100 ml of water. After stirring for 10 hours at room temperature, the reaction mixture is acidified with 50 ml of 6N hydrochloric acid and then extracted with 200 ml of toluene. The toluene phase is washed twice with water and then completely concentrated under reduced pressure. The 0.0-di-isopropyl-S-carboxymethyl dithiophosphate is thus obtained as a light yellow oil.

Die aussergewöhnlichen Lasttrageeigenschaften der Verbindungen der Formel I als Schmiermittelzusätze zeigen sich auch bei der Prüfung im FZG-Zahnradverspannungsprüfstand. The exceptional load-bearing properties of the compounds of formula I as lubricant additives can also be seen in the test on the FZG gear tension test bench.
Zu diesem Zweck wurden Mischungen der Verbindungen der Formel I in einem nicht-legierten mineralischen Schmieröl (Viskosität: 20 cSt/50 °C) hergestellt und mit der FZG-Maschine nach DIN 51354 (Nortmaltest A/8.3/90) geprüft. Vergleichsweise wurde auch das nicht-legierte mineralische Schmieröl ohne Zusatz mit der FZG-Maschine geprüft. For this purpose, mixtures of the compounds of formula I were produced in a non-alloyed mineral lubricating oil (viscosity: 20 cSt / 50 ° C) and tested with the FZG machine according to DIN 51354 (Nortalt Test A / 8.3 / 90). By comparison, the non-alloyed mineral lubricating oil without additives was also tested with the FZG machine.
Die Ergebnisse dieser Untersuchungen sind in der nachstehenden Tabelle 3 zusammengestellt. The results of these tests are summarized in Table 3 below.

Mit dem Shell-Vierkugel-Apparat wurden folgende Werte bestimmt: (Tentative method IP 239/69, Extense pressure and wear lubricant test for oils and greases, four ball-machine). The following values were determined using the Shell four-ball apparatus: (Tentative method IP 239/69, Extense pressure and wear lubricant test for oils and greases, four ball-machine).
1.1.S.L. = Initial Seizure Load: Das ist die Last, bei der der Ölfilm innerhalb einer Belastungsdauer von 10 Sekunden zusammenbricht. 1.1.S.L. = Initial Seizure Load: This is the load at which the oil film breaks down within a load period of 10 seconds.
2. W.L. = Weld Load (Schweisslast). Das ist die Last, bei der die 4 Kugeln innerhalb von 10 Sekunden zusammen-schweissen. 2. W.L. = Weld Load. This is the load that the 4 balls weld together within 10 seconds.
3. W.S.D. = Wear Scar Diameter in mm: Das ist der mittlere Verschleissdurchmesser bei einer Belastung von 70 kg bzw. 40 kg während 1 Stunde. 3. W.S.D. = Wear Scar Diameter in mm: This is the average wear diameter with a load of 70 kg or 40 kg over 1 hour.
Als Basisöl wurde Catenex 41 (Handelsbezeichnung der 3 Firma Shell) verwendet. Catenex 41 (trade name of the 3 Shell company) was used as the base oil.
