Description

DEUTSCHESGERMAN

Die Erfindung betrifft ein Isolieröl auf der Basis eines raffinierten Mineralöles mit einem Zusatz von 0,1 bis 10 Gewichtsprozent (bezogen auf die Ölbasis) eines durch Crackung, katalytische Hydrierung oder Alkylierung erhaltenen, ein geringeres mittleres Molekulargewicht als die Ölbasis und einen Siedebereich von 160' bis 350° C mit einem Hauptsiedebereich über 200° C aufweisenden Erdölkohlenwasserstoffgemisches nach Patentanmeldung O 4256 IVc/23c, und besteht darin, daß dieser Zusatz mehr als 20 Volumprozent, vorzugsweise mehr als 50 Volumprozent, monocyclischer Aromaten enthält, wobei die Aromatenan teile in, bekannter Weise im Zusatz angereichert sind.The invention relates to an insulating oil based on a refined mineral oil with an addition of 0.1 to 10 percent by weight (based on the oil base) of one by cracking, catalytic hydrogenation or Alkylation obtained, a lower average molecular weight than the oil base and a boiling range from 160 'to 350 ° C with a main boiling range above 200 ° C having petroleum-hydrocarbon mixture according to patent application O 4256 IVc / 23c, and consists in the fact that this addition is more than 20 percent by volume, preferably more than 50 percent by volume, monocyclic aromatics, the aromatics on parts are enriched in a known manner in addition.

Es wurde gefunden, daß der gewünschte Effekt hinsichtlich Gasaufnahme, Verbesserung der Alterungsbeständigkeit und des Verlustfaktors besonders günstig ist, wenn der Zusatz dieses Erdölkohlenwasserstoffgemisches einen hohen Gehalt an monocyclischen Aromaten aufweist. Es konnte festgestellt werden, daß eine Konzentration dieser monocyclisehen Aromaten aus irgendeinem der genannten· aromatenhaltigen Ausgangsstoffe zu Produkten führt, deren Wirksamkeit parallel mit dem Gehalt an monoeyclischen Aromaten ansteigt. Dabei ist die Konzentration dieser Aromaten in bekannter Weise durchzuführen, z. B. durch Extraktion mit S O2, durch Extraktion mit Diäthylenglykol oder nach einem anderen bekannten Verfahren. Die Wirksamkeit dieser monoeyclischen Aromaten unterliegt hinsichtlich des Siedebereichs keinen weiteren Einschränkungen, als daß dieser Siedebereich bereits in der Hauptpatentanmeldung festgelegt ist, d. h. also, daß auch der mit monoeyclischen Aromaten angereicherte Zusatz einen Siedebereich zwischen 160 und 350° C mit einem Hauptsiedebereich von 200° C besitzen muß. Entspricht die durch die Aromatenanreicherung gewonnene Fraktion nicht diesem Siedebereich, wird eine Fraktion im Siedebereich zwischen 160 und 350° C mit einem Hauptsiedebereich von 200° C herausgeschnitten.It has been found that the desired effect with regard to gas uptake, improvement of the aging resistance and the loss factor is particularly favorable if the addition of this petroleum-hydrocarbon mixture has a high content of monocyclic aromatics. It was found that a concentration of these monocyclic aromatics from any of the aromatic-containing starting materials mentioned leads to products whose effectiveness increases in parallel with the content of monocyclic aromatics. The concentration of these aromatics is to be carried out in a known manner, e.g. B. by extraction with SO 2 , by extraction with diethylene glycol or by another known method. The effectiveness of these monoeyclic aromatics is not subject to any further restrictions with regard to the boiling range, other than that this boiling range is already specified in the main patent application, i.e. that the additive enriched with monoeyclic aromatics also has a boiling range between 160 and 350 ° C with a main boiling range of 200 ° C must own. If the fraction obtained through the aromatic enrichment does not correspond to this boiling range, a fraction in the boiling range between 160 and 350 ° C with a main boiling range of 200 ° C is cut out.

Von den aus den britischen Patentschriften 589 149 und 589 150 bekanntgewordenen hochmolekularen Aromaten unterscheidet sich das aromatenreiche Kohlenwasserstoffgemisch gemäß der Erfindung sowohl hinsichtlich der Menge als auch hinsichtlich des Molekulargewichtes und des Siedebereiches.Of the high molecular weight known from British patents 589 149 and 589 150 The aromatic-rich hydrocarbon mixture according to the invention differs both from aromatics with regard to the amount as well as with regard to the molecular weight and the boiling range.

Gegenstand eines älteren Patentes ist ein Verfahren zur Herstellung eines elektrischen Isolieröles aus einem mit einem aromatenarmen Raffinatöl verschnittenen aromatischen Extrakt eines Mineralöldestillates. Eine Siedebegrenzung der Aromaten ist nicht festgelegt. The subject of an earlier patent is a process for producing an electrical insulating oil from an aromatic extract of a mineral oil distillate blended with a low-aromatic raffinate oil. A boiling limit for aromatics is not specified.

mit 98% Aromaten wurde einem gasabspaltenden Transformatorenöl zugesetzt. Um die gleiche Gasaufnahmekurve zu erhalten, wie sie durch den Zusatz von 1,5 Gewichtsprozent einer üblichen Fraktion aus dem Platformerbenzin entsteht, brauchten nur 0,7 Gewichtsprozent dieses aromatenreichen Benzins, dessen Siedegrenzen 160 bis 350° C mit einem Hauptsiedebereich von 200° C betragen, zugesetzt werden, wobei der Verlustfaktor von 0,21 · 10-3 auf 0,1 · lO^3 gesenkt wurde.with 98% aromatics was added to a gas-releasing transformer oil. In order to obtain the same gas uptake curve as is produced by adding 1.5 percent by weight of a conventional fraction from the platform gasoline, you only need 0.7 percent by weight of this aromatic-rich gasoline, whose boiling point is 160 to 350 ° C with a main boiling range of 200 ° C are added, wherein the loss factor of 0.21 x 10- 3 to 0.1 x lO ^ was lowered. 3
