  Verfahren zur Herstellung von   Transformatorenöl   aus Teerölen. 



   Die Erfindung betrifft ein Verfahren zur Herstellung von Transformatorenöl aus Teerölen. 



   Es hat sich gezeigt, dass beim Behandeln von Teerölen mit Oxydationsmitteln, wie Kaliumbichromat-, Kaliumpermanganatmischung u. dgl. bei niedrigen Temperaturen eine Umwandlung der Teeröle in der Art vor sich geht, dass sie in zähflüssige Harze und flüssige Öle, die als Transformatorenöle verwendbar sind, getrennt worden. 



   Man kann entweder die Teeröle direkt mit einer Oxydationsmischung behandeln oder 
 EMI1.1 
 kann, indessen darf die Temperatur Zimmertemperatur nicht übersteigen. 



    Ausführungsbeispiele :'     I.   100 kg Teeröle werden   auf - 15 bis - 200   C abgekühlt und mit einer Kaliumbichromatmischung etwa eine Stunde lang unter Umrühren behandelt. Man lässt dann die Mischung Zimmertemperatur annehmen. Beim Stehen setzt sich aus der Mischung ein zähflüssiges Harz ab. Das darüber stehende Öl wird abgetrennt und einer Raffination mit 2 bis   3%   66iger Schwefelsäure unterworfen. Nach dem Abziehen der Schwefelsäure und Auswaschen wird dann das Öl im Vakuum destilliert. 



   2. 100 kg Teeröl werden in 100   kg   Benzin gelöst und alsdann bei o bis 50 oxydiert. 



  Im übrigen verfährt man nach Abdestillation des Lösungsmittels genau wie nach Beispiel i. 



   Man hat bereits vorgeschlagen, Teeröle mit Sauerstoff oder Luft zu behandeln. Bei diesem Verfahren wird jedoch bei- höheren Temperaturen gearbeitet, bei denen eine Verdickung zur Pechbildung eintritt. Im vorliegenden Falle sollen jedoch gerade flüssige Öle hergestellt werden. Infolgedessen wird bei niedriger Temperatur gearbeitet.

  Process for the production of transformer oil from tar oils.



   The invention relates to a method for producing transformer oil from tar oils.



   It has been shown that when treating tar oils with oxidizing agents such as potassium dichromate, potassium permanganate mixture and the like. Like. At low temperatures, the tar oils are converted in such a way that they have been separated into viscous resins and liquid oils which can be used as transformer oils.



   You can either treat the tar oils directly with an oxidation mixture or
 EMI1.1
 can, however, the temperature must not exceed room temperature.



    EXEMPLARY EMBODIMENTS: 1. 100 kg of tar oils are cooled to −15 to −200 ° C. and treated with a potassium dichromate mixture for about one hour while stirring. The mixture is then allowed to reach room temperature. When standing, a viscous resin is deposited from the mixture. The oil above is separated off and refined with 2 to 3% 66% sulfuric acid. After the sulfuric acid has been stripped off and washed, the oil is then distilled in vacuo.



   2. 100 kg of tar oil are dissolved in 100 kg of gasoline and then oxidized at 0 to 50.



  Otherwise, after distilling off the solvent, the procedure is exactly as in Example i.



   It has already been proposed to treat tar oils with oxygen or air. In this process, however, work is carried out at higher temperatures at which thickening occurs to form pitch. In the present case, however, liquid oils are to be produced. As a result, the temperature is low.
