Description
- Die vorliegende Erfindung betrifft Prozeßflüssigkeiten, z. B. Hydraulikflüssigkeiten und Schmierstoffe
- Der Verwendung von flammenhemmenden Phosphatflüssigkeiten in verschiedenen Anwendungen hat in letzter Zeit rasch zugenommen. Zum einen haben sie sich als eine sichere Alternative zum Gebrauch entflammbarer Flüssigkeiten auf Mineralölbasis nützlich erwiesen und zum anderen, erst vor kurzem, als Ersatz für halogenierte aromatische Verbindungen, gegen die aus Umweltgründen Einwände erhoben wurden.
- Diese Flüssigkeiten müssen über lange Zeiträume hydrolytisch stabil sein, damit ein Eindringen von Feuchtigkeit keine Verschlechterung des Leistungsvermögens der Flüssigkeit verursacht. Obwohl die Anwesenheit von Feuchtigkeit in der Flüssigkeit bis zu einem gewissen Grade durch die Anwesenheit von Additiven wie Rostschutzmitteln, Koadditiven wie Antioxidantien, Metallpassivatoren und Hochdruckadditiven bekämpft werden kann, können sie in Gegenwart von Feuchtigkeit saure Produkte erzeugen, die den Zerfall der Grundflüssigkeit katalysieren können.
- Im Fall von Flüssigkeiten auf Mineralölbasis sind üblicherweise Epoxyverbindungen eingeschlossen, um die Entwicklung einer feuchtigkeitsinduzierten Acidität zu bekämpfen. Wenn Epoxide zu diesem Zweck in Formulierungen auf Phosphatbasis eingeschlossen sind, ist jedoch gezeigt worden, daß deren Anwesenheit nachteilig ist.
- Die GB-A 1277179 offenbart Schmierstoffzusammensetzungen auf Esterbasis, die als Metallkorrosionsschutzmittel eine die Struktureinheit -CONHN=C enthaltende Verbindung enthalten.
- Überraschenderweise haben wir gefunden, daß bestimmte Harnstoff- und Semicarbazonderivate Prozeßflüssigkeiten, die für eine hydrolytische Zersetzung anfällig sind, eine wirksame hydrolytische Stabilität verleihen.
- Folglich stellt die vorliegende Erfindung eine Prozeßflüssigkeit bereit, umfassend:
- a) eine Grundflüssigkeit, ausgewählt aus einer oder mehreren von i) einer Phosphatflüssigkeit und ii) einem Carbonsäureester; und
- b) als Hydrolysestabilisator mindestens eine Verbindung der Formel I:
- A-NHC(=X)NHZ (I),
- in der A ein Wasserstoffatom, einen C&sub1;-C&sub1;&sub2;-Alkyl-, C&sub3;-C&sub1;&sub8;- Alkenyl-, C&sub6;-C&sub1;&sub0;-Aryl-, C&sub7;-C&sub1;&sub3;-Alkaryl-, C&sub7;-C&sub1;&sub3;-Aralkyl- oder C&sub5;-C&sub1;&sub2;-Cycloalkylrest bedeutet;
- X ein Sauerstoff- oder Schwefelatom oder eine NH-Gruppe darstellt und
- Z ein H-Atom, eine NH&sub2;-Gruppe oder einen Rest -N=CR&sub1;R&sub2; bedeutet, in dem R&sub1; und R&sub2; voneinander unabhängig eine der A zugeordneten Bedeutungen aufweisen oder R&sub2; ein H-Atom darstellt oder R&sub1; und R&sub2; zusammen mit dem Kohlenstoffatom, an das sie beide gebunden sind, einen C&sub5;-C&sub1;&sub2;-Ring bilden können, mit den Maßgaben, daß
- A) wenn X ein Sauerstoffatom darstellt und Z ein Wasserstoffatom bedeutet, A keine Benzylgruppe oder keinen Alkaryl- oder Aralkylrest darstellt, der in der α-Stellung verzweigt ist;
- B) wenn X eine NH-Gruppe bedeutet und A ein Wasserstoffatom darstellt, Z keinen Rest -N=C bedeutet, wobei R&sub1; und R&sub2; Alkyl- oder Arylreste darstellen;
- C) wenn die Grundflüssigkeit a) ein Carbonsäureester ist und X ein Schwefelatom bedeutet, Z kein Wasserstoffatom darstellt;
- D) wenn die Grundflüssigkeit a) ein Carbonsäureester ist, X ein Sauerstoffatom bedeutet und A ein Wasserstoffatom darstellt, Z keinen Rest -N=C bedeutet, wobei R&sub1; ein Wasserstoffatom oder einen Alkylrest darstellt, R&sub2; einen Alkylrest bedeutet oder R&sub1; und R&sub2; einen C&sub5;-C&sub1;&sub2;-Ring bilden, und
- E) wenn die Grundflüssigkeit a) ein Carbonsäureester ist, X ein Sauerstoffatom darstellt und Z ein Wasserstoffatom bedeutet, A keinen Alkenyl- oder Alkylrest mit mehr als 4 Kohlenstoffatomen darstellt.
- Die Disclaimer A bis E betreffen Zusammensetzungen, die in US-A-3 324 031, US-A-3 655 560, US-A-3 296 136, GB-A-1 120 997, GB-A-1 277 179 und DE-A-2 138 569 offenbart sind.
- Ein weiterer Gegenstand der Erfindung ist die Verwendung von 2-Octanonsemicarbazon, Cyclododecanonsemicarbazon, Cyclopentanonsemicarbazon, Hexanalsemicarbazon oder Benzalsemicarbazon als Hydrolysestabilisatoren in einer Prozeßflüssigkeit, die einen Hauptteil aus einer Phosphatflüssigkeit oder einem Carbonsäureester umfaßt.
- Mit dem Begriff "Phosphatflüssigkeit" meinen wir ein beliebiges Triarylphosphat oder gemischtes Alkylphenyl/Phenylphosphat, vorzugsweise gemischtes Isopropylphenyl/Phenylphosphat. Typische Beispiele sind diejenigen, die z. B. in der US-A-3 576 023 beschrieben sind. Synthetische Prozeßflüssigkeiten und Schmierstoffe, die Triarylphosphate unterschiedlicher Typen enthalten, sind auch in US-A-2 938 871, 3 012 057, 3 071 549, 3 468 802, 3 723 315 und 3 780 145 beschrieben. Spezielle Beispiele solcher Phosphate sind Trikresylphosphat (Tritolylphosphat), Trixylylphosphat, Kresyldiphenylphosphat, Diphenylethylphenylphosphat, Butyldiphenylphosphat, Dikresylxylylphosphat, Dibutylphenylphosphat, Tributylphosphat, Triamylphosphat, Trioctylphosphat und Tri(isopropylphenyl)phosphat und gemischte Alkylphenyl/Phenylphosphate wie diejenigen, die in der in der GB-A-1146173 beschriebenen Weise durch Phosphorylierung z. B. eines Isopropylphenol/Phenolgemisches, das durch Alkylierung von Phenol mit 10-40 Gew.-% Propylen erhalten wird, hergestellt werden, oder gemischte t-Butylphenyl/Phenylphosphate wie diejenigen, die durch Phosphorylierung eines t-Butylphenol/Phenolgemisches, das durch Alkylierung von Phenol mit 10-30 Gew.-% Isobutylen erhalten wird, hergestellt werden.
- Carbonsäureestergrundflüssigkeiten können Di-, Tri- oder Tetraester, komplexe Ester oder Polyester sein.
- Diester können z. B. Ester der Formel:
- R&sub3; -OOC-alkylen-COO-R&sub4;
- sein, wobei "alkylen" einen C&sub2;-C&sub1;&sub4;-Alkylenrest darstellt und R&sub3; und R&sub4; gleich oder verschieden sind und jeweils einen C&sub1;-C&sub2;&sub0;-Alkylrest und vorzugsweise einen C&sub6;-C&sub1;&sub8;-Alkylrest bedeuten.
- Triester, die als Grundflüssigkeiten verwendet werden können, sind diejenigen, die von Trimethylolpropan und C&sub6;-C&sub1;&sub8;-Monocarbonsäuren oder Gemischen davon abgeleitet werden, während geeignete Tetraester z. B. diejenigen einschließen, die von Pentaerythrit und einer C&sub6;-C&sub1;&sub8;-Monocarbonsäure oder Gemischen davon abgeleitet werden.
- Zur Verwendung als Grundflüssigkeiten geeignete komplexe Ester sind z. B. diejenigen, die von einbasigen Säuren, zweibasigen Säuren und mehrwertigen Alkoholen abgeleitet werden, zum Beispiel der komplexe Ester, der von Trimethylolpropan, Caprylsäure und Sebacinsäure abgeleitet wird.
- Geeignete Polyester sind z. B. diejenigen, die von einer C&sub4;-C&sub1;&sub4;-Dicarbonsäure und mindestens einem aliphatischen zweiwertigen C&sub3;-C&sub1;&sub2;-Alkohol abgeleitet werden, z. B. diejenigen, die von Azelainsäure oder Sebacinsäure und 2,2,4-Trimethylhexan-1,6-diol abgeleitet werden.
- Bevorzugte Carbonsäureestergrundflüssigkeiten sind Diester und Pentaerythrittetraester. Das Gemisch aus einer Phosphatflüssigkeit und einem Dicarbonsäureester ist auch bevorzugt.
- Die Grundflüssigkeit kann inerte Verdünnungsmittel, z. B. Mineralöle, enthalten.
- Wenn ein Rest A in den Verbindungen der Formel I einen Alkylrest darstellt, kann er eine Methyl-, Ethyl-, n-Propyl-, Isopropyl-, n-Butyl-, t-Butyl-, n-Pentyl-, n-Hexyl-, n-Octyl-, n-Decyl- oder n-Dodecylgruppe sein; Alkenylreste schließen eine Allyl-, Methallyl-, 1-Octadecenyl- und Octadec-9-en-1-ylgruppe ("Oleylgruppe") ein; Aryl- oder Alkarylreste schließen eine Phenyl-, Tolyl-, p-Butylphenyl-, Naphthyl- und Methylnaphthylgruppe ein; Aralkylreste A können z.
