teile des Destillierens mit Wasserdampf zu Nutze zu machen, weil der eingeblasene Wasserdampf die Wasserentziehung aus dem Destillat unmöglich macht. Man war daher bisher genötigt, wenn man ohne Zersetzung destillieren will, zuerst mit eingeblasene Wasserdampf zu arbeiten und nachträglich, wenn eine vollkommene Wasserfreiheit angestrebt wird, eine Entwässerung vorzunehmen, entweder durch Erhitzen über 100 J oder durch Zusatz von wasserentziehenden Mitteln. Im ersteren Falle kann die Qualität des Destillates durch das längere Erhitzen sehr verschlechtert werden und im zweiten Falle gelingt es oft nicht, die wasserentziehenden Mittel oder deren Reaktionsproduktc mit dem Destillat auf mechanischem Wege wieder zu entfernen.
Man ist meistens gezwungen, zu einer nochmaligen Destillation mit direkter Feuerung zu schreiten, die bei einem wärmeempfindlichen Destillationsgut die in der Beschreibung des Stammpatentes erwähnten pyrogenen Zersetzungen zur Folge hat.
Es ist auch schon für die Destillation von Kohlenwasserstoffen die elektrische Heizung vorgeschlagen worden, aber es ist bisher nicht vorgeschlagen worden eine nach dem Stammpatent geleitete elektrische Destillation bei geringem Temperaturgefälle mit der Behandlung des Destillates durch wasserentziehende Mittel, wie Natrium, Kalium usw. zu verbinden, um auf diese Weise in einem Arbeitsgang einfachster Art die hochwertigsten, ganz zersetzungsfreien und wasserfreien Destillate unmittelbar zu erhalten, wobei diese Arbeitsweise ohne jede Komplikation und bei verhältnismässig niederen Gestehungskosten durchführbar ist.
In der Mineralöldestillation gelingt es z. B. auf diese Weise, durch Natrium oder Kalium nicht nur das Wasser vollkommen zurückzuhalten, sondern es werden auch alle schwefelhaltigen Substanzen, alle Stoffe sauren und phenolischen Charakters und alle harzartigen Bestandteile, die zur späteren Polymerisation neigen, in einer Weise gebunden, dass sie bei der Destillation, als bei den höchsten Temperaturen nicht flüchtige Bestandteile, zurückbleiben und man so Öle erhält, die selbst bei hohen Viskositäten von

kommen überflüssig machen. Gleichzeitig wird durch die elektrische Methode das Destillat vor pyrogenem Zerfall bewahrt.
Es gelingt auch, durch das vollständige Zurückhalten von Wasser und allen die elek- trische Leitfähigkeit beeinflussenden Substanzen, die eben genannt wurden, Transformatoren-und Schalter- öle zu erhalten, die sich durch vorzügliche Isolationswerte auszeichnen und erst bei sehr hohen Span-

to make use of parts of the distillation with steam, because the steam blown in makes it impossible to remove water from the distillate. So far, if you want to distill without decomposition, you have to work first with blown water vapor and then, if you want to achieve complete freedom from water, drain the water, either by heating over 100 J or by adding dehydrating agents. In the first case the quality of the distillate can be greatly impaired by prolonged heating and in the second case it is often not possible to remove the dehydrating agents or their reaction products with the distillate again by mechanical means.
In most cases, one is forced to proceed to another distillation with direct firing, which results in the pyrogenic decomposition mentioned in the description of the parent patent in the case of heat-sensitive material to be distilled.
Electric heating has also been proposed for the distillation of hydrocarbons, but so far it has not been proposed to combine an electric distillation at a low temperature gradient based on the parent patent with the treatment of the distillate by means of dehydrating agents such as sodium, potassium, etc. In this way, in a single step of the simplest type, the highest quality, completely decomposition-free and water-free distillates can be obtained directly, this method of operation being feasible without any complications and at relatively low production costs.
In the mineral oil distillation z. B. in this way not only to hold back the water completely by sodium or potassium, but also all sulfur-containing substances, all substances of acidic and phenolic character and all resinous constituents that tend to polymerize later are bound in such a way that they are of the distillation, as non-volatile constituents at the highest temperatures, remain and so oils are obtained that even at high viscosities of

make come redundant. At the same time, the electrical method prevents the distillate from pyrogenic decomposition.
It is also possible, through the complete retention of water and all of the substances that have an impact on the electrical conductivity, which have just been mentioned, to obtain transformer and switch oils that are characterized by excellent insulation values and only at very high voltage.
