Description

Schmiermittel Es wurde gefunden, daß man sehr gut brauchbare Schmiermittel erhält, indem man die in dem sogenannten Kühleröl enthaltenen verseifbaren und die Hydroxylgruppen enthaltenden unverseifbaren Anteile miteinander verestert. Unter Kühleröl ist das ölartige Gemisch aus Fettsäuren, Alkoholen, Aldehyden, Ketonen und Kohlenwasserstoffen zu verstehen, das als Nebenerzeugnis der Fettsäuresynthese durch Paraffinoxydation aus der Abluft der Oxydationsöfen durch Kondensation mittels indirekter Kühlung gewonnen wird und beim üblichen Oxydationsverfahren durch Blasen mit Luft in einer Ausbeute von etwa 6 bis 9 0/0, berechnet auf den verarbeiteten Frischgatsch, anfällt.Lubricants It has been found that lubricants are very useful obtained by the saponifiable contained in the so-called cooler oil and the Unsaponifiable fractions containing hydroxyl groups are esterified with one another. Under Radiator oil is the oily mixture of fatty acids, alcohols, aldehydes and ketones and hydrocarbons are understood as a by-product of fatty acid synthesis by paraffin oxidation from the exhaust air of the oxidation ovens by means of condensation indirect cooling is obtained and in the usual oxidation process by blowing with air in a yield of about 6 to 9%, calculated on the processed Frischgatsch, accrues.

Da in dem rohen Kühleröl die Menge der verseifbaren Carboxylgruppen enthaltenden Anteile die der unverseifbaren Hydroxylgruppen enthaltenden Anteile übersteigt, ist es zweckmäßig, dem Kühleröl vor der Veresterung noch gewisse Mengen von aus Kühleröl abgetrennten, unverseifbaren Hydroxylgruppen enthaltenden Bestandteilen hinzuzufügen, und zwar so viel, daß in dein Gemisch die Carboxy 1- und Hydroxylgruppen in annähernd äquivalenten Mengen vorhanden sind. Man kann aber auch unmittelbar das rohe Kühleröl, gegebenenfalls nach Abdestillieren des rliedrigst siedenden Anteils von etwa 6 bis to o/o, der neben Wasser niedere, wasserlösliche Fettsäuren enthält, der Veresterung unterwerfen. Man kann ferner auch sowohl aus dem Kühleröl wie aus dein Unverseifbaren höhersiedende, beispielsweise über 17o° oder über 300° siedende Anteile abtrennen und nur diese der Veresterung - unterwerfen, wodurch man höhersiedende Ester erhält. Einen ähnlichen Erfolg kann man auch erreichen, indem man aus dem rohen Ester, der aus .dem gesamten Kühleröl bzw. dem gesamten LTnv erseifbaren gewonnen wurde, die niedrigsiedenden Anteile durch Destillation entfernt. Die Veresterung erfolgt nach an sich bekannten Verfahren, beispielsweise mittels Schwefelsäure. Salzsäure oder organischen Sulfonsäuren als Katalysatoren.As in the crude radiator oil, the amount of saponifiable carboxyl groups The proportions containing the proportions containing the unsaponifiable hydroxyl groups it is advisable to add certain amounts to the radiator oil before esterification of constituents containing unsaponifiable hydroxyl groups which have been separated off from cooler oil add so much that the carboxy 1 and hydroxyl groups in your mixture are present in approximately equivalent amounts. But you can also directly the crude radiator oil, optionally after distilling off the lowest-boiling portion from about 6 to o / o, which in addition to water contains lower, water-soluble fatty acids, subject to esterification. You can also both from the radiator oil and from your unsaponifiable higher boiling one, for example over 170 ° or over 300 ° boiling Separate portions and only these of the esterification - subject, whereby one higher boiling Ester receives. Similar success can also be achieved by moving out of the Crude ester, which is obtained from the entire cooler oil or the entire LTnv saponifiable was removed, the low-boiling components by distillation. the Esterification takes place according to processes known per se, for example by means of sulfuric acid. Hydrochloric acid or organic sulfonic acids as catalysts.

Die technischen Vorteile der Ester aus Isülileröl bei der Verwendung als Schinie rmittel oder als Zusatz zu solchen beruhen auf der im Vergleich zu tierischen und pflanzlichen Fetten und Ölen viel höheren Beständigkeit gegen Oxydation und hohe Temperaturen, dem Fehlen jeglicher korrodierender Eigenschaften, der auffallend geringen Abhängigkeit derViscosität von derTemperattir (flaelie Viscositätsl:ttrve), der besonders leichten Emulgierbarkeit der Ester und der Beständigkeit ihrer Emulsionen. Dementsprechend eignen sich die Ester, soweit sie ölcharakter haben, besonders als Spindelöle, Webstuhlöle, im Gemisch finit Einulgatoren als Grundstoffe für Bohröle und Bohrölextrakte und für sonstige Zwecke der Metallbearbeitung, «-o es auf Erliöliung der Gleitfälligkeit find Kühlwirkung ankommt, als Zusatz zur Verbesserung von 1lineralschinierölen und als Rostschutzmittel, beispielsweise in Gewehrölen. Die salbenartigen bis festen Ester eignen sich besonders als konsistente Schmiermittel bzw. als Zusatz zu solchen, beispielsweise auch zu Ziehmitteln.The technical advantages of the esters from Isülileröl when used as a compound or as an addition to such are based on the compared to animal and vegetable fats and oils much higher resistance to oxidation and high temperatures, the lack of any corrosive properties, which is conspicuous low dependence of the viscosity on the temperature (flaelie Viscositätsl: ttrve), the particularly easy emulsifiability of the esters and the stability of their emulsions. Accordingly, the esters, insofar as they have the character of an oil, are particularly suitable as Spindle oils, loom oils, finite emulsifiers in a mixture as base materials for drilling oils and drilling oil extracts and for other metalworking purposes, «-o it on erliöliung the lubricity is important for the cooling effect, as an additive to improve lineral lubricating oils and as a rust inhibitor, for example in gun oils. The ointment-like to firm ones Esters are particularly suitable as consistent lubricants or as additives to those for example also to drawing means.
