Description

Verfahren zur Erhöhung der Durchschlagfestigkeit von chlorierten Diphenylen Chlordiphenyle, wie sie mit verschiedenen Viscositätsgraden bei der Chlorierung von Diphenylen erhalten werden können, insbesondere auch solche mit einem Chlorgehalt zwischen etwa 40 und 6o %, sind als elektrische Isolierstoffe bekannt.Process for increasing the dielectric strength of chlorinated diphenyls Chlorodiphenyls, as they are with different degrees of viscosity in chlorination can be obtained from diphenylene, especially those with a chlorine content between about 40 and 60% are known as electrical insulating materials.

Es wurde nun gefunden, daß die Durchschlagfestigkeit dieser Stoffe erhöht werden kann, wenn man sie einem starken elektrischen Feld bis zum Durchschlag aussetzt und dann einer Destillation, z. B. im Vakuum, unterwirft. Auf diese bequeme und billige Weise lassen sich auch Chlordiphenyle regenerieren, deren Durchschlagfestigkeit infolge von Durchschlägen gesunken ist. Es zeigt z. B. ein destilliertes chloriertes Diphenyl mit einem Chlorgehalt von 5 5 bis 56 % bei i I Durchschlägen eine Durchschlagfestigkeit von im Durchschnitt 136 KV/cm. Dieses durchgeschlagene Chlordiphenyl wurde 2o nunmehr wieder destilliert und zeigt dann eine Durchschlagfestigkeit von im Durchschnitt 176 KV/cm, das entspricht einer Zunahme der Durchschlagfestigkeit um 30010. It has now been found that the dielectric strength of these substances can be increased if they are exposed to a strong electric field until the breakdown and then a distillation, z. B. in a vacuum, subject. In this convenient and inexpensive way, chlorodiphenyls can also be regenerated whose dielectric strength has decreased as a result of breakdowns. It shows e.g. B. a distilled chlorinated diphenyl with a chlorine content of 5 5 to 56% with i I breakdowns a dielectric strength of an average of 136 KV / cm. This breakthrough chlorodiphenyl has now been distilled again 20 and then shows an average dielectric strength of 176 KV / cm, which corresponds to an increase in the dielectric strength of 30,010.
