Description
Verfahren zur Herstellung von Transformatorenöl aus Teeröl. Die Erfindung betrifft ein Verfahren zur Herstellung von Transformatorenöl aus Teerölen.Process for the production of transformer oil from tar oil. The invention relates to a process for the production of transformer oil from tar oils.
Es hat sich kezeigt, daß beim Behandeln von Teerölen mit Oxydationsmitteln, wie Kaliunilbichromat-, Kaliumpermanganatmischnng u. d,gl. bei niedrigen Temperaturen eine Unrivandlung der Teeröle in der Art vor sich geht, daß sie in zähflüssige Harze und flüssige Öle, die als Transformatorenöle verwendbar sind, getrennt werden.It has not been shown that when treating tar oils with oxidizing agents, such as potassium dichromate, potassium permanganate mixture, etc. at low temperatures the tar oils are not transformed into viscous resins and liquid oils useful as transformer oils are separated.
Man kann entweder die Teeröle direkt mit einer Oxydationsmischung behandeln oder aber in einem Lösungsmittel gelöst, das von dem Oxydationsmittel unangreifbar ist.You can either use the tar oils directly with an oxidation mixture treat or dissolved in a solvent from the oxidizing agent is invulnerable.
Diese Aus:führtingsforin bietet den Vorteil, daB man bei Temperaturen von etwa o° C arbeiten kann.This design offers the advantage that one can work at temperatures can work from about o ° C.
Ausführungsbeispiele: i. ioo kg Teeröl werden auf --- 15 bis 2o° 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 0I wird abgetrennt und einer Raffination mit .2 bis 3 Prozent 66iger Schwefelsäure unterworfen. Nach dem- Abziehen der Schwefelsäure und Auswaschen wird dann das Öl im Vakuum destilliert.Embodiments: i. 100 kg of tar oil are heated to --- 15 to 20 ° C cooled and mixed with a potassium dichromate mixture for about an hour while stirring treated. The mixture is then allowed to reach room temperature. When standing, sets A viscous resin is formed from the mixture. The OI above is separated and subjected to refining with .2 to 3 percent 66% sulfuric acid. To After stripping off the sulfuric acid and washing it out, the oil is then distilled in vacuo.
2. ioo kg Teeröl werden in ioo kg Benzin gelöst und alsdann bei o bis 5° oxydiert. Im übrigen verfährt man nach Abdestillation des Lösungsmittels genau wie nach Beispiel i.2. 100 kg of tar oil are dissolved in 100 kg of gasoline and then at o Oxidized up to 5 °. Otherwise, the procedure is followed by distilling off the solvent exactly as in example i.
Man hat bereits vorgeschlagen, Teeröle mit Sauerstoff oder Luft zu behandeln. Bei diesem Verfahren, wird jedoch bei höheren Temperaturen gearbeitet, bei denen eine Verdikkung bis zur Pechbildung eintritt. Im vorliegenden Falle sollen jedoch gerade flüssige Öle hergestellt werden. Infolgedessen wird bei niedrigerer Temperatur gearbeitet.It has already been proposed to add oxygen or air to tar oils treat. This process, however, is carried out at higher temperatures, in which a thickening occurs up to the formation of pitch. In the present case however, it is precisely liquid oils that are produced. As a result, the lower Temperature worked.
