Description
- Öle für die Metallbearbeitung Es wurde gefunden, daß sich Öle oder wäßrige Olemulsionen mit einem Gehalt an Nitrilen, Amiden oder Estern von Carbonsäuren der allgemeinen Formel R (XRICOOH)n in besonderer Weise bei der Bearbeitung von Metallen verwenden lassen. In dieser Formel bedeuten R und R1 Kohlenwasserstoffreste, welche wenigstens einen gesättigten, aliphatischen oder cyclischen Kohlenwasserstoffrest mit mindestens 6 Kohlenstoffatomen enthalten, X Schwefel oder,Sauerstofff und ii die Zahlen r bis 4. In diesen Verbindungen sind somit eine oder mehrere Carboxylgruppen, die durch Vermittlung des Kohlenwasserstoffrestes R1 äther- oder thioätherartig über ein oder mehrere Sauerstoff- oder Schwefelatome an den Kohlenwasserstoffrest R gebunden sind, vorhanden. Diese Verbindungen sind z.B. erhältlich durch Umsetzung von gesättigten aliphatischen oder cyclischen Alkoholen, Phenolen, Merkaptanen oder Thiophenolen mit Halogencarbonsäuren oder durch Anlagerung von Acrylnitril an die genannten Verbindungen und anschließende Verseifung der gebildeten Oxypropionnitrile und Thioätherpropionnitrile oder beispielsweise durch Umsetzung vön Alkoholen, Phenolen, Merkaptanen oder Thiophenolen mit Laktonen, wie z. B. y-B,utyrolakton. Besonders wirksam sind die Verbindungen, die -aus technischen Alkoholen, Phenolen, Merkaptanen oder Thiophenolen hergestellt werden. Beispielsweise können als Ausgangsstoffe verwendet werden die Alkohole, welche aus Olefinen durch Anlagerung an Kohlenoxyd und Wasserstoff entstehen, ferner die Alkohole, welche man bei der Reduktion von Kohleoxyd mit Wasserstoff in Gegenwart besonderer Katalysatoren erhält, oder die Merkaptane, welche man erhält, wenn man natürliche oder synt'hetisc'he gesättigte aliphatische oder cyclischeKo'hlenwasserstoffe unter Bestrahlung mit kurzwelligem ,Licht gleichzeitig mit Chlor und SO, behandelt und die gebildeten Sulfochloride nach bekannten Methöden zu den Merkaptanen reduziert. Es kommen ferner in Frage alkylierte oder cycloalkylierte Aryl- bzw. Ilydroaryloxocarbonsäuren oder entsprechende Aryl- bzw. Hydroarylthioäthercarbonsäuren. Für viele Zweige der Metallbearbeitung, so z. B. zum Bohren, Schleifen, Schneiden, Fräsen, Räumen u. dgl. können die genannten Carbonsäurederi.vate unmittelbar eingesetzt werden, und zwar genügen in vielen Fällen Konzentrationen von o,i °/o und weniger bis etwa io %.
- Sollen die genannten Carbonsäurederivate als Emulgatoren für Mineralöle u. dgl. verwandt werden, z. B. zur Herstellung von Bohrölen, so werden sie zweckmäßigerweise mit den für die Metallbearbeitung bestimmten Ölen gemischt. In den Mischungen werden die Carbonsäuren teilweise oder völlig mit Ammoniak oder organischen Basen neutralisiert. Man kann auch die Carbonsäurederivate mit den Ölen mischen.
- Die Öle oder Kohlenwasserstoffe können auch bereits von der Herstellung her in den genannten Carbonsäuren enthalten sein. Den Mischungen aus Ölen und den Carbonsäurederivaten kann man zur Homogenisierung noch geringe Mengen Wasser oder andere Lösungsvermittler zusetzen. Als solche seien z. B. genannt Dekahydronaphthalen, Terpenkohlenstoffe, Terpenalkohole, höhermolekulare aliphatische Alkohole, cycloaliphatische Alkohole, Glykoläther, Phenole oder Amidocarbönsäuren. In manchen Fällen kann auch ein Zusatz von Harnstoff vorteilhaft sein. Es können auch andere Dispergiermittel, wie z. B. höhermolekulare Sulfon- oder Carbonsäuren bzw. deren Salze oder Umsetzungsprodukte von Äthylenoxyd mit höhermolekularen Oxy-, Carboxyl- oder Aminogruppen enthaltenden Verbindungen mitverwendet werden. Hierdurch wird die Wirkung in vielen Fällen gesteigert oder einem bestimmten Verwendungszweck angepaßt. Die Erzeugnisse zeichnen sich außer durch hervorragende mechanische Eigenschaften durch sicheren Korrosionsschutz aus.
- Beispiele i. Eine Fraktion gesättigter aliphatischer Kdhlenwasserstoffe aus der Kdhleoxydredukti;on mit der Siedegrenze 230 bis 320° wird unter Bestrahlung mit kurzwelligem Licht gleichzeitig mit Chlor und schwefeliger Säure behandelt, und zwar so lange, bis etwa die Hälfte des Umsetzungsgemisches aus aliphatischen Sulfochloriden und unveränderten aliphatischen Kohlenwasserstoffen besteht. Das Umsetzungserzeugnis wird in bekannter Weise, z. B. durch Behandlung mit Zinkstaub in schwefelsaurer Lösung, in ein Gemisch von aliphatisehen Merkaptanen und gesättigten aliphatischen Kohlenwasserstoffen übergefüihrt.
- Dieses Kohlenwasserstoff - Alkylmerkaptan - Gemisch wird mit Acrylnitril behandelt. Das. Gemisch der gebildeten Alkylthioätherpropionnitrile wird z. B. in Form der wäBrigen Mineralölemulsionen als Bohröl verwendet. Es kann auch unmittelbar ohne Zumisahung von Mineralölen als Bohrmittel, ferner als Schneidöl, als Kühl- und Gleitmittel bei allen Zweigen der Metallbearbeitung mit besonderem Vorteil verwendet werden. Es kommen für die meisten Fälle nur i- bis 5o/oige Lösungen in Wasser in Frage. Bei ganz schweren Metalfbearbeitungsprozessen ist es unter Umständen erforderlich, die Konzentration auf etwa 8 bis io o/o zu erhöhen.
- 2. Mit dem gleichen Erfolg kann man auch die Ester, Amide oder Nitrile einer Alkoxyessigsäure, hergestellt durch Umsetzung eines Alkoliolgemi.sches mit etwa 12 bis 16 Kohlenstoffatomen im Molekül, mit Chloressigsäure in Gegenwart von Alkali, verwenden.
