Description

Verfahren zur Herstellung neutraler, satzfreier, luftbeständiger, mit Mineralölen mischbarer Steinkohlenteerschmieröle. Das Hauptpatent bezieht sich auf ein Verfahren zur Herstellung heller, satzfreier, luftbeständiger, mit Mineralölen mischbarer Steinkohlenteerschmieröle, das dadurch gekennzeichnet ist, daß die Phenole entfernt werden aus dem Teerfettöl durch Einwirkung von Alkali bei der Destillationstemperatur. Man geht dabei vorteilhaft so vor, daß ein Teil des Phenols durch Behandlung mit wässeriger Alkalilauge entfernt wird und nach der Trennung das Teerfettöl mit dem darin verbliebenen Rest von Alkali destilliert wird. Dieses heiße Destillat wird dann rasch abgekühlt auf tiefe Temperatur, z. B. -5', vorteilhaft im Vakuum, und dann unter Innehaltung dieser tiefenTemperatur, gleichfalls vorteilhaft im Vakuum, von den Ausscheidungen befreit, um so auch gleichzeitig dauernd satzfrei bleibende Teeröle zu erhalten.Process for the production of neutral, sentence-free, air-resistant, Coal tar lubricating oils that can be mixed with mineral oils. The main patent relates on a process for the production of lighter, residue-free, air-resistant, with mineral oils Miscible coal tar lubricating oils, which is characterized in that the phenols are removed from the tar oil by the action of alkali at the distillation temperature. It is advantageous to proceed in such a way that some of the phenol is treated with aqueous alkali solution is removed and after the separation the tar oil with the remaining in the residue of alkali is distilled. This hot distillate will then rapidly cooled to low temperature, e.g. B. -5 ', advantageously in a vacuum, and then while maintaining this low temperature, also advantageously in a vacuum, freed from the excretions, all the more so at the same time that they remain sentence-free Obtain tar oils.

Es wurde nun weiter gefunden, daß man nicht erst nötig hat, die Teerfettöle aus dem Teer herzustellen und dann diese zu behandeln, sondern daß man wasserfreies Alkali auf die übergehenden Dämpfe einwirken lassen kann. Man hat es so nicht nötig, erst aus dem Teer das Teerfettöl herzustellen.It has now been found that one does not need the tar fat oils first from the tar and then to treat it, but that one is anhydrous Alkali can act on the passing vapors. You don't need to first make the tar oil from the tar.
