Description

Schmiermittel Die bekannten Schmieröle sind auf Basis der fetten Öle oder der Mineralöle aufgebaut. Diese Basis betrifft sowohl die natürlich vorkommenden Öle als auch die synthetisch hergestellten.Lubricants The known lubricating oils are based on fatty oils or the mineral oils. This basis applies to both naturally occurring ones Oils as well as those synthetically produced.

Dabei zeichnen sich die fetten Öle durch eine besonders gute Schmierfähigkeit aus, während die Mineralschmieröle bei geringerer Schmierfähigkeit eine bedeutend bessere Beständigkeit gegen höhere Temperaturen zeigen. Man ging schon frühzeitig dazu über, die guten Eigenschaften beider Schmierölarten zu kombinieren, indem man die Schmiereigenschaften der Mineralöle durch Zusätze von fetten Ölen verbesserte. Man gelangte so zu den kompondierten Ölen. Diese Öle fanden als Flugmotoren-, Automobil-, Uhrenöle und besonders als Schiffsmaschinenöle Verwendung. In letzter Zeit sind Verfahren bekanntgeworden, Mineralölen Oxyalkylamine bzw. deren Verbindung mit Fettsäuren in geringen Mengen zuzusetzen. So beschreibt z: B. ein Verfahren den Zusatz von maximal 5,010() zu einem Gemisch von Rizinus- und Mineralöl. Die italienische Patentschrift 349I39 beschreibt den Zusatz von o,oi bis o,oi5,1)/a Triäthanolamin als Korrosionsverhinderer zu Gemischen von Rizinusöl und Mineralöl. Des weiteren ist bekannt der Zusatz eines Kondensationsproduktes aus i Mol Triäthanolamin und 3 Mol Stearinsäure zu Maschinenöl. Die USA.-Patentschrift 2 0'18 758 beschreibt die Erniedrigung des Stockpunktes von Mineralölen durch Zusatz der Verbindungen -von Methanol-, Äthanol-, Propanol- und Butanolamin mit Fettsäuren von iobis 22 C .Atomen im Molekül. Diese Verbindungen werden in Mengen bis zu ioo/o den Mineralölen zugesetzt. Allen diesen Schmierölen ist gemeinsam, däß durch Zusatz geringer Mengen von Oxyalkylaminen bzw. deren Verbindungen die schon vorhandene Schmierfähigkeit des Schmieröls bzw. die korrosionsverhindernde Wirkung verbessert wird.The fatty oils are characterized by a particularly good lubricity off, while the mineral lubricating oils have a significantly lower lubricity show better resistance to higher temperatures. You left early about combining the good properties of both types of lubricating oil by adding Improved the lubricating properties of mineral oils by adding fatty oils. This is how the composed oils were obtained. These oils were found as aircraft engines, automotive, Watch oils and especially used as marine machine oils. Lately are Process has become known, mineral oils oxyalkylamines or their connection with fatty acids to be added in small amounts. For example: a procedure describes the addition of a maximum of 5.010 () for a mixture of castor and mineral oil. The Italian patent specification 349I39 describes the addition of o, oi to o, oi5,1) / a triethanolamine as a corrosion inhibitor for mixtures of castor oil and mineral oil. The addition of a is also known Condensation product from 1 mole of triethanolamine and 3 moles of stearic acid to form machine oil. US Pat. No. 2,018,758 describes the lowering of the pour point of Mineral oils by adding the compounds of methanol, ethanol, propanol and Butanolamine with fatty acids from iobis 22 C .atoms in the molecule. These Compounds are added to the mineral oils in amounts of up to 100%. All of these What lubricating oils have in common is that by adding small amounts of oxyalkylamines or the compounds of which the already existing lubricity of the lubricating oil or the corrosion-preventing effect is improved.

Nach der Erfindung kommt man zu vorzüglichen Schmierölen, wenn man als schmierendes Prinzip nicht das Mineralöl oder das fette Öl, sondern di; Verbindungen von Fettsäuren mit Oxyalkylaminen selbst benutzt. Diese Körperklasse stellt viskose bis wachsartige Verbindungen dar, die in Mischungen mit Körpern, die selbst eine geringere Schmierfähigkeit haben, ausgezeichnete Schmieröle ergibt. Hierbei ist es erforderlich, daß das Oxyalkylamin bzw. dessen Verbindung einen wesentlichen Bestandteil des Schmieröls ausmacht. Vorteilhaft ist es, wenn das Schmieröl einen geringen Prozentsatz Oxyalkylamn in freier Form enthält. Als Zusatz eignen sich aromatische Kahlenwasserstoffe, aliphatische Kohlenwasserstoffe, Alkohole, Glykole, Ester, Ketone usw. mit entsprechendem Flammpunkt. Durch das Mischungsverhältnis von fettsauren Oxyalkylaminen und den genannten Verbindungen hat man es in der Hand, die verschiedensten Viskositäten einzustellen. Ausführungsbeispiele i. ioiookg Vorlauffettsäure aus der Oxydation der Kohlenoxydhydrierungsprodukte werden mit 6oo kg z, 3-Butylenglykol verestert. Nach der Entfernung der noch vorhandenen freien Fettsäure durch Alkali wurde der Ester im Vakuum destilliert. Zu 95,kg dieses Esters gibt man 5!okg eines Produktes, das man erhält, wenn man entsprechende Mengen Ölsäure und Triäthanolamin bei go° unter Umrühren verseift. Man erhält ein Schmieröl mit folgenden Kennzahlen: Ego = 12,8; Flammpunkt i8o°; Trübungspunkt -18'.According to the invention, you get excellent lubricating oils if you as a lubricating principle, not the mineral oil or the fatty oil, but di; links used by fatty acids with oxyalkylamines themselves. This body class represents viscous to represent waxy compounds that are in mixtures with bodies that are themselves a have lower lubricity, make excellent lubricating oils. Here is it is necessary that the oxyalkylamine or its compound has a substantial Constitutes part of the lubricating oil. It is advantageous if the lubricating oil one contains a small percentage of oxyalkylamn in free form. Are suitable as additives aromatic hydrocarbons, aliphatic hydrocarbons, alcohols, glycols, Esters, ketones etc. with a corresponding flash point. By the mixing ratio of fatty acid oxyalkylamines and the compounds mentioned you have it in hand, to set the most varied of viscosities. Embodiments i. ioiookg first run fatty acid from the oxidation of the carbohydrate hydrogenation products with 600 kg of z, 3-butylene glycol esterified. After removing the remaining free fatty acids with alkali the ester was distilled in vacuo. To 95 kg of this ester add 5! Okg of one Product obtained by adding appropriate amounts of oleic acid and triethanolamine saponified at go ° while stirring. A lubricating oil is obtained with the following key figures: Ego = 12.8; Flash point i8o °; Cloud point -18 '.

Fettsäuren aus der Paraffinoxydation mit einem C-Gehalt von 8 bis 12, werden mit Triäthanolamin derart verseift, daß das Verseifungsprodukt 0,3!"/a freies Triäthanolämin enthält. 7o Teile dieses Verseifungsproduktes werden mit 5R5, Teilen Nonylalkohol versetzt. Das Schmieröl hat eine Viskosität von 22 Englergrad, einen Flammpunkt von iig° und einen Trübungspunkt von -i5°.Fatty acids from paraffin oxidation with a carbon content of 8 to 12, are saponified with triethanolamine in such a way that the saponification product 0.3! "/ A Contains free triethanolamine. 7o parts of this saponification product are mixed with 5R5, Parts of nonyl alcohol are added. The lubricating oil has a viscosity of 22 degrees, a flash point of iig ° and a cloud point of -i5 °.
