Definitions
- the present invention relates to the use of N, N-di-substituted S-thiiranylmethylcarbamothioates as lubricant additives and lubricant compositions containing them.
- Additives are usually added to mineral and synthetic lubricants to improve their performance. Additives that protect the device to be lubricated from frictional wear are of particular importance. Such additives are required to increase the load-bearing capacity of the lubricant, not to have a corrosive effect on the metal parts to be lubricated and to have good heat resistance.
- compounds containing phosphorus and sulfur are preferably used today, e.g. Dialkyldithiophosphate according to DE-A 2,921,620.
- the phosphorus content of lubricating oils should be kept as low as possible so that the catalysts are not deactivated (H.S. Vogel et al., Applied Catalysis 3 (1982), 79-82).
- N, N-disubstituted S-thiiranylmethylcarbamothioates and their use as herbicides are known, for example, from US Pat. No. 3,634,457.
- the use of the compounds mentioned as lubricant additives has not yet been described.
- N, N-disubstituted S-thiiranylmethylcarbamothioates in mineral and synthetic lubricants have excellent properties with regard to protection from frictional wear, laundering and ashlessness.
- the invention therefore relates to compositions containing a lubricant and at least one compound of the formula I.
- R 1 and R 2 independently of one another are C 1 -C 24 -alkyl, which can optionally be interrupted once or more by -0-, -S- or / and -N- and / or which optionally has one or more oxo- or / and can contain thiono groups, C 3 -C 24 alkenyl, C 2 -C 4 hydroxyalkyl, C 5 -C 8 cycloalkyl, or unsubstituted or with one or two C 1 -C 12 alkyl, C 1 -C 4 -Alkoxy-, C 2 -C 24 -alkoxycarbonyl or / and nitro groups substituted phenyl, naphthyl, C 7 -C 10 aralkyl, furan-2-yl-methyl or tetrahydrofuran-2-yl-methyl or R 1 and R 2 together with the
- R 1 and R 2 are C 1 -C 24 -alkyl, they are straight-chain or branched substituents, for example methyl, ethyl, n-propyl, isopropyl, n-, sec- or tert-butyl, 1, 3-dimethylbutyl, 2-ethylbutyl, n-pentyl, isopentyl, 1-methylpentyl, n-hexyl, 2-ethylhexyl, n-heptyl, isoheptyl, 1-methylheptyl, n-octyl, straight-chain or branched nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, octadecyl or eicosyl.
- Preferred is C I -C 20 -, especially C 1 -C 12
- Alkyl substituents R 1 and R 2 which are represented by -0-, or / and -S-interrupted and / or substituted with oxo or / and thiono groups, preferably have 2-18, in particular 3-12, especially 3-7 C atoms. Particular mention should be made of alkoxyalkyl, alkoxyalkoxy, polyalkoxy (especially polyethoxy) alkyl, alkylthioalkyl, alkylaminoalkyl and dialkylaminoalkyl radicals.
- the oxo or thiono groups can, for example, also sit on a carbon atom adjacent to a -0-, -N- or -S-chain link, which results in alkyl chains which are interrupted, for example, by ester, amide or thioester functions.
- alkyl chains which are interrupted, for example, by ester, amide or thioester functions.
- examples of such radicals are, for example, those of the formula -alkylene-C00-alkyl, -alkylene-CON-alkyl or -alkylene-C (S) 0-alkyl.
- the chain length of alkylene + alkyl is as described above for the entire alkyl radical.
- Preferred alkyl radicals with heteroatoms are those which, as shown above, contain ester or amide functions, but in particular alkoxyalkyl (for example with 3-7 C atoms), alkoxyalkoxyalkyl or polyethoxyalkyl, for example polyethoxyethyl.
- alkyl radicals R 3 which may be mentioned are: methyl, ethyl, n-propyl, isopropyl, n-, sec- or tert-butyl, 1,3-dimethylbutyl, 2-ethylbutyl, n-pentyl, isopentyl, 1-methylpentyl, n-hexyl, 2-ethylhexyl, n-heptyl, isoheptyl, 1-methylheptyl, n-octyl.
- R 3 is preferably hydrogen or C 1 -C 4 -alkyl.
- R 1 and R 2 with the meaning C 2 -C 4 -hydroxyalkyl can be, for example, 2-hydroxyethyl, 2-hydroxypropyl, 3-hydroxypropyl, 2-hydroxybutyl or 4-hydroxybutyl, 2-hydroxyethyl being preferred.
- R 1 and R 2 are, for example, allyl, butenyl, pentenyl or hexenyl, octenyl, decenyl, dodecenyl or oleyl. Preferred is C 3 -C 18 , especially C 3 -C 7 alkenyl, especially allyl. If R 1 and R 2 are C 3 -C 8 cycloalkyl, it is, for example, cyclopentyl, cyclohexyl, 4-methylcyclohexyl or cyclooctyl. Here R 1 and R 2 are preferably a C 5 -C 6 cycloalkyl radical and particularly preferably a cyclohexyl radical.
- R 1 and R 2 as phenyl mono- or disubstituted with C 1 -C 12 alkyl or C 1 -C 4 alkoxy, C 2 -C 24 alkoxycarbonyl and / or nitro, for example 2-, 3- or 4-Tolyl, xylyl, 4-isopropylphenyl, 4-tert-butylphenyl, 3-methoxyphenyl or 4-propoxyphenyl, 3-carbethoxyphenyl or 3-nitrophenyl.
- a phenyl radical is only substituted with one type of substituent.
- An alkoxycarbonyl substituent preferably has 2-18, in particular 2-12, especially 2-5 C atoms.
- R 1 and R 2 are preferably phenyl which is mono- or disubstituted by C 1 -C 4 -alkyl radicals.
- R 1 and R 2 is a C 7 -C lo aralkyl radical may be, for example, benzyl, a-methylbenzyl, a, a-dimethylbenzyl, 1-phenylethyl, 2-phenylethyl, 2-phenylpropyl, 3- Act phenylpropyl or 3- (4-tolyl) propyl.
- the meaning of benzyl for R 1 and R 2 is preferred.

Abstract
Description
- Die vorliegende Erfindung betrifft die Verwendung von N,N-diaubsti- tuierten S-Thiiranylmethylcarbamothioaten als Schmiermittelzusätze und Schmiermittelzusammensetzungen, die diese enthalten.
- Mineralischen und synthetischen Schmiermitteln werden üblicherweise Zusatzstoffe zur Verbesserung der Gebrauchseigenschaften zugesetzt. Von besonderer Bedeutung sind Additive, welche die zu schmierende Vorrichtung vor Reibungsabnutzung schützen. An solche Additive wird die Anforderung gestellt, dass sie das Lasttragevermögen des Schmiermittels erhöhen, nicht korrodierend auf die zu schmierenden Metallteile wirken und eine gute Hitzebeständigkeit besitzen.
- Hierfür werden heute vorzugsweise phosphor- und schwefelhaltige Verbindungen verwendet wie z.B. Dialkyldithiophosphate gemäsa der DE-A 2,921,620. Im Hinblick auf die Verwendung von Katalysatoren im Abgassystem von Verbrennungsmotoren soll jedoch der Phosphorgehalt von Schmierölen möglichst tief gehalten werden, damit die Katalysatoren nicht desaktiviert werden (H.S. Gandhi et al., Applied Catalysis 3 (1982), 79-82).
- N,N-disubstituierte S-Thiiranylmethylcarbamothioate und deren Einsatz als Herbizide sind zum Beispiel aus der US-A 3,634,457 bekannt. Eine Verwendung der genannten Verbindungen als Schmiermittel-Additive wurde bis jetzt noch nicht beschrieben.
- Man hat nun gefunden, dass N,N-disubstituisrte S-Thiiranylmethylcarbamothioate in mineralischen und synthetischen Schmiermitteln ausgezeichnete Eigenschaften hinsichtlich Schutz vor Reibungsabnutzung, Laattragevermögen und Aschefreiheit aufweiaen.
- Die Erfindung betrifft daher Zusammensetzungen, enthaltend ein Schmiermittel und wenigstens eine Verbindung der Formel I
worin R1 und R2 unabhängig voneinander C1-C24-Alkyl, das gegebenenfalls einmal oder mehrmals durch -0-, -S- oder/und -N- unterbrochen sein kann oder/und das gegebenenfalls eine oder mehrere Oxo- oder/und Thionogruppen enthalten kann, C3-C24-Alkenyl, C2-C4-Hydroxyalkyl, C5-C8-Cycloalkyl, oder unsubstituiertes oder mit einer oder zwei C1-C12-Alkyl-, C1-C4-Alkoxy-, C2-C24-Alkoxycarbonyl- oder/und Nitrogruppen substituiertes Phenyl, Naphthyl, C7-C10-Aralkyl, Furan-2-yl-methyl oder Tetrahydrofuran-2-yl-methyl bedeuten oder R1 und R2 zusammen mit dem N-Atom, an das sie gebunden sind, einen 5- oder 6-gliedrigen einkernigen aliphatisch-heterocyclischen Ring, der ausser dem N-Atom noch ein oder zwei N-, O-oder/und S-Atome als Ringglieder oder/und eine oder zwei Oxooder/und Thionogruppen als Substituenten enthalten kann, oder einen unsubstituierten oder mit 1 bis 3 Methylgruppen substituierten Indolinyl-, 1,2,3,4-Tetrahydrochinolinyl- oder 1,2,3,4-Tetrahydroisochinolinylrest bilden, und R3 Wasserstoff oder C1-C8-Alkyl ist. - Stehen R1 und R2 für C1-C24-Alkyl, handelt es sich um geradkettige oder verzweigte Substituenten, zum Beispiel Methyl, Ethyl, n-Propyl, Isopropyl, n-, sec.- oder tert.-Butyl, 1,3-Dimethylbutyl, 2-Ethylbutyl, n-Pentyl, Isopentyl, 1-Methylpentyl, n-Hexyl, 2-Ethylhexyl, n-Heptyl, Isoheptyl, 1-Methylheptyl, n-Octyl, geradkettiges oder verzweigtes Nonyl, Decyl, Undecyl, Dodecyl, Tridecyl, Tetradecyl, Pentadecyl, Hexadecyl, Octadecyl oder Eicosyl.

Besonderes zu nennen sind dabei Alkoxyalkyl, Alkoxyalkoxy-, Polyalkoxy- (insbesondere Polyethoxy)alkyl-, Alkylthioalkyl-, Alkylaminoalkyl- und Dialkylaminoalkylreste. Die Oxo- oder Thionogruppen können z.B. auch an einem einem -0-, -N- oder -S-Kettenglied benachbarten C-Atom sitzen, wodurch Alkylketten entstehen, die z.B. durch Ester-, Amid- oder Thioesterfunktionen unterbrochen sind.

Insbesondere ist ein solcher Phenylrest nur mit einer Substituentenart substituiert. Ein Alkoxycarbonylsubstituent hat vorzugsweise 2-18, insbesondere 2-12, vor allem 2-5 C-Atome. Vorzugsweise stellen hierbei R1 und R2 einfach oder zweifach mit C1-C4-Alkyl-Resten substituiertes Phenyl dar.

Sie wirken ausserdem nicht korrosiv auf die zu schmierenden Metallteile. Die Verbindungen der Formel I wirken schon in sehr geringen Mengen in Schmiermitteln. So zeigen mineralische und synthetische Schmieröle sowie deren Gemische, welche mit 0,05 bis 5 Gew.-%, bezogen auf das Schmiermittel, und vorzugsweise mit 0,05 bis 3 Gew.-% einer Verbindung der Formel I ausgestattet sind, ausgezeichnete Eigenschaften, insbesondere Verschleissschutz-Eigenschaften. Die in Frage kommenden Schmiermittel sind dem Fachmann geläufig, und z.B. in "Schmierstoffe und verwandte Produkte" (Verlag Chemie, Weinheim, 1982) beschrieben.
- Die erfindungsgsmässen Additive sind in mineralischen und synthetischen Schmierstoffen thermostsbil; sie sind aschefrei und phoaphorfrei. Letzteren ist insbesandere wichtig im Hinblick auf die Verwendung von Schmiermitteln in Verbrennungsmotoren mit Katalyaatoren im Abgassystem, die durch Phoaphoorrütänds schneller altern.
- Die Erfindung betrifft daher auch die Verwendung von Verbindungen der Formel I gemäss Anspruch 1 als Zusätze zu mineraliachen und synthetischen Schmiermitteln.
- Die Schmierstoffe können zusätzlich andere Additive enthalten, die zugegeben werden, um die Grundeigenschaften von Schmierstoffen noch weiter zu verbessern; dazu gehören: Antioxidantien, Metallpasaivatoren, Rostinhibitoren, Viskositätsindex-Verbesserer, Stockpunkterniedriger, Dispergiermittel, Detergentien, sowie weitere Hochdruck-Zusätze und Antiverschleiss-Additive.

- Schwefel und/oder Phosphor und/oder Halogen enthaltende Verbindungen, wie geachwefelte pflanzliche Oele, Zinkdialkyldithiophoaphate, Tritolyl-phoaphat, chlorierte Paraffine, Alkyl- und Aryldiaulfide.
- Die folgenden Beispiele erläutern die Erfindung näher:
-
- Zu einer Suspension von 24,3 g (0,1 mol) Natrium-N-cyclohexyl,N-ethyl-dithiocarbamat-monohydrat in 200 ml Toluol wird eine Lösung von 8,2 ml (0,1 mol) Epichlorhydrin in 100 ml Toluol zugetropft. Nach Zugabe von 10 ml Methanol geht die klare Lösung in eine Suspension über, wobei die Temperatur von 25°C auf 65°C ansteigt. Zum Ausreagieren wird bei 50°C 30 min. weitergerührt. Dann wird gut mit Wasser gewaschen, die organische Phase über Natriumsulfat getrocknet und im Vakuum eingedampft. 24 g hellgelbes, mittelviskoses Oel werden mit Toluol als Eluiermittel durch 200 g Silicagel filtriert und eingedampft. Man erhält so 11,7 g S-Thiiranylmethyl-N-cyclohexyl,N-ethyl-carbalmothioat (45 % Ausbeute) als farbloses mittelviskoses Oel.
- Analyse (%): berechnet: C 55,56 H 8,16 N 5,40 S 24,72 gefunden: C 55,56 H 8,09 N 5,37 S 24,37
-
- Zu einer gut gerührten Mischung von 7,8 ml (9,25 g, 0,1 mol) Epichlorhydrin und 6,0 ml (7,6 g, 0,1 mol) Schwefelkohlenstoff werden innerhalb von 1 Std. bei S 30°C 19,8 ml (20,3 g, 0,1 mol) Dibenzylamin zugetropft (stark exotherm). Dann wird unter leichtem Vakuum (11-50 Torr) während 1,5 Std. bei 80°-90°C weitergerührt.
- Das dickflüssige Oel wird mit 100 ml Toluol verdünnt und mit 14,0 ml (0,1 mol) Triethylamin versetzt.
- Der dicke Brei wird mit weiteren 200 ml Toluol verdünnt und mit gesättigter Natriumchloridlösung gewaschen, über Natriumsulfat getrocknet, durch 300 g Silicagel filtriert und eingedampft. Man erhält so 25,1 g S-Thiiranylmethyl-N,N-bis(phenylmethyl)-carbamothioat (74 %) als klares, dickflüssiges, hellgelbliches Oel. nD20 = 1,6186.
- Analyse (%): berechnet: C 65,62 H 5,81 N 4,25 S 19,46 gefunden: C 65,54 H 5,84 N 4,24 S 19,62
-
- Mit dem Shell-Vierkugel-Apparat werden nach der ASTM-StandardMethode D 2783-81 (extreme preasure and wear lubricant test for oils and greases, four ball-machine) folgende Werte bestimmt:
- 1. W.L. = Weld load (Schweiealast). Das ist die Last, bei der die 4 Kugeln innerhalb von 10 Sekunden susammenachweisaea.
- 2. W.S.D. = Wear Scar Diameter in mm: Das ist der mittlere Verschleiasdurchmesser bei einer Belastung von 400 N während 1 Stunde.
