Description

Schmieröle Als Schmieröle verwendet man Mineralöle, fette Öle oder Gemische von beiden. Dabei zeichnen sich die Mineralöle durch besonders gute Beständigkeit aus, ohne allerdings das Schmiervermögen der fetten Öle zu erreichen. Dagegen ist für fette Öle ihr außerordentliches Schmiervermögen charakteristisch, wobei man eine geringere Alterungsbeständigkeit in Kauf nehmen muß. In ihrem Verhalten gegen Wasser zeigen sie auch nur einen graduellen Unterschied. Mineralöle sind in Wasser unlöslich und schwer emulgierbar, während fette Öle bei gleicher Unlöslichkeit je nach Konstitution und Raffinationsgrad ein gewisses Emulsionsvermögen zeigen können.Lubricating oils Mineral oils, fatty oils or a mixture of both are used as lubricating oils. The mineral oils are characterized by particularly good resistance, without, however, reaching the lubricating power of fatty oils. On the other hand, fatty oils are characterized by their extraordinary lubricity, whereby one has to accept a lower resistance to aging. In their behavior towards water they also show only a gradual difference. Mineral oils are insoluble in water and difficult to emulsify, while fatty oils with the same insolubility can show a certain emulsifiability depending on their constitution and degree of refinement.

Für besondere Zwecke ist es indessen notwendig, ein Öl herzustellen, das in Wasser vollkommen emulgierbar oder wasserlöslich ist. Man hat wohl versucht, Mineralöle und fette Öle durch Zusatz von Emulgatoren emulgierbar zu machen. Dieses Verfahren versagt aber beim Vorhandensein größerer Mengen Wasser. Hierbei werden nämlich die Emulgatoren ausgewaschen, und die Schmieröle steigen wieder an die Oberfläche des Wassers, ganz abgesehen davon, daß hierdurch keine wasserlöslichen Öle herstellbar sind.For special purposes, however, it is necessary to produce an oil that is completely emulsifiable or water-soluble in water. Attempts have been made to make mineral oils and fatty oils emulsifiable by adding emulsifiers. However, this process fails when large amounts of water are present. This is because the emulsifiers are washed out and the lubricating oils rise again to the surface of the water, quite apart from the fact that no water-soluble oils can be produced as a result.

Es wurde nun gefunden, daß Mischungen von Reaktionserzeugnissen von Oxyalkylaminen und Fettsäuren oder Naphthensäuren mit solchen Alkoholen, Ketonen, Alkyl- oder Arylestern von aliphatischen gesättigten oder ungesättigten Carbonsäuren, die zusammen mit den Reaktionsprodukten in Wasser löslich sind und einen Flammpunkt von über etwa 7o' besitzen, ausgezeichnete Schmiereigenschaften haben.It has now been found that mixtures of reaction products of Oxyalkylamines and fatty acids or naphthenic acids with such alcohols, ketones, Alkyl or aryl esters of aliphatic saturated or unsaturated carboxylic acids, together with the reaction products in water are soluble and have a flash point above about 7o ', excellent lubricating properties to have.

Als Mischungskomponenten können z. B. die verschiedensten wasserlöslichen ein- oder mehrwertigen Alkohole, wie Glykole und Glycerin, ferner Ester, wie Butyllaktat u. dgl., verwendet werden.As components of the mixture, for. B. the most diverse water-soluble monohydric or polyhydric alcohols such as glycols and glycerol, and esters such as butyl lactate and the like, can be used.

Nimmt man als Fettsäuren für die Reaktionsprodukte mit Oxyalkylaminen solche niedermolekularer Natur, wie sie z. B. ein Gemisch der Säuren C4 - C" aus der Oxydation von Kohlenwasserstoffen darstellen, so erhält man Schmieröle mit tiefem Stockpunkt. So stockt beispielsweise ein Erzeugnis aus dem Verseifungsprodukt von Triäthanolamin mit Fettsäuren mit 4 bis io C-Atomen aus der Oxydation von Kohlenwasserstoffen in Mischung mit Butyllaktat erst bei unterhalb -45'.If the fatty acids used for the reaction products with oxyalkylamines are of a low molecular weight, such as those used, for. If, for example, a mixture of acids C4 - C "is obtained from the oxidation of hydrocarbons, lubricating oils with a low pour point are obtained Mix with butyl lactate only below -45 '.

Die Öle werden mit Vorteil dort eingesetzt, wo es darauf ankommt, daß sie sich nicht aus hinzutretendem Wasser ausscheiden, sondern in ihm gelöst oder feinst dispergiert bleiben.The oils are used to advantage where it matters that they are not separated from the water that flows in, but rather dissolved in it or remain finely dispersed.

Ausführungsbeispiele 1. 18,5 Teile eines Verseifungsproduktes aus Triäthanolamin und synthetischen Fettsäuren aus der Paraffinoxydation mit 5 bis io C-Atomen werden mit 6o Teilen Triäthvienglykol vermischt. Dieses Gemisch stellt ein ausgezeichnetes Schmieröl dar mit der Viskosität E" = 12,3, dem spezifischen Gewicht i,i und einem Flammpunkt von 163'. Dieses Öl ist noch unterhalb -4o' flüssig und löst sich spielend in Wasser.Working Examples 1. 18.5 parts of a saponification product made from triethanolamine and synthetic fatty acids from paraffin oxidation with 5 to 10 carbon atoms are mixed with 60 parts triethanolamine. This mixture is an excellent lubricating oil with the viscosity E " = 12.3, the specific weight i, i and a flash point of 163 '. This oil is still liquid below -4o' and easily dissolves in water.

2. go Teile des im Beispiel i beschriebenen Verseifungsproduktes von Triäthanolamin wurden mit 7o Teilen Butyllaktat versetzt. Das Gemisch hat eine Viskosität von- 12,7 Engler bei 2o', ein spezifisches Gewicht von i,o2 und einen Flammpunkt von 94'. Der Trübungspunkt dieses Schmieröls liegt bei -45'. Von Wasser wird es sofort aufgelöst.2. Go parts of the saponification product of described in Example i 7o parts of butyl lactate were added to triethanolamine. The mixture has a viscosity of -12.7 Engler at 2o ', a specific gravity of 1.02 and a flash point of 94 '. The cloud point of this lubricating oil is -45 '. From water it becomes resolved immediately.
