Verfahren zur Reinigung von Mineral-, Teer- und ähnlichen Ölen, sowie deren Destillaten.
Dem üblichen Verfahren zur Raffination von Mineralölen mittels Schwefelsäure haften gewisse allgemein bekannte Übelstände an. Zu ihrer Vermeidung sind verschiedene Vor- schläge gemacht worden, welche meist auf einer Extraktion, fraktionierten Fällung oder
Absorption beruhen.
Dass die bekannten Extraktionsverfahren von Landsberg, Däschner und Diamand sich keine grössere Verbreitung sichern konnten, liegt einerseits daran, dass sie. gleichgültig ob sie bestimmt sind selektierend zu wirken oder nur die Asphaltstoffe usw. zu lösen, be- deutende Mengen (fünf-bis zehnfache) an teuren, leicht flüchtigen Extraktionsmitteln be- nötigen, wodurch grosse Verluste an solchen bedingt sind, andrerseits daran, dass die Pro- dukte stets gewisse Gruppen von Kohlenwasserstoffen enthalten, die labiler Natur sind und bei der Verwendung Übelstände, wie Verharzung usw., hervorrufen. Überhaupt müssen die
Produkte des Extraktionsverfahrens noch einer Nachraffination mit Säure unterworfen werden, da Geruch-und Farbstoffe meist in allen Fraktionen verteilt sind.
Letzteres trifft auch bei den Verfahren von Edeleanu besonders bei der Herstellung von Schmieröl zu, weil infolge der Verwendung von flüssiger schwefeliger Säure die erhaltenen Raffinate alle sauren
Anteile enthalten, sauer reagieren und dunkel gefärbt sind.
Es hat sich nun gezeigt, dass man in den organischen Amiden Mittel besitzt, welche sowohl chemisch durch Einwirkung auf die sauren, farb-und geruchgebenden Anteile, als auch physikalisch dadurch wirken, dass sie ungesättigte, zyklische usw. Kohlenwasserstoffe lösen, die gesättigten, aliphatischen usw. Kohlenwasserstoffe jedoch ungelöst lassen.
Beispiel : Man mischt ioo kg Mineralöldestillat mit 100 kg Anilin. Hierbei bilden sich zwei Schichten, von welchen die obere ein helles, raffiniertes Öl darstellt, das nach
Abdestillieren der letzten Anilinreste etwa 92 kg Fertigprodukt liefert.

Process for cleaning mineral, tar and similar oils and their distillates.
The usual process for refining mineral oils using sulfuric acid has certain well-known disadvantages. To avoid them, various proposals have been made, which are mostly based on extraction, fractionated precipitation or
Based on absorption.
The fact that the well-known extraction processes from Landsberg, Däschner and Diamand were not able to secure a wider distribution is partly due to the fact that they. Regardless of whether they are intended to have a selective effect or only to dissolve the asphalt materials, etc., require significant amounts (five to ten times) of expensive, highly volatile extractants, which causes great losses of such, on the other hand because the Products always contain certain groups of hydrocarbons that are unstable in nature and cause problems such as resinification etc. when used. They have to
Products of the extraction process are also subjected to post-refining with acid, since odor and color are mostly distributed in all fractions.
The latter also applies to the Edeleanu processes, particularly in the manufacture of lubricating oil, because, as a result of the use of liquid sulphurous acid, the raffinates obtained are all acidic
Contain parts, react acidic and are dark in color.
It has now been shown that there are agents in the organic amides which act both chemically by acting on the acidic, color and odorous components, and physically by dissolving unsaturated, cyclic etc. hydrocarbons, the saturated, aliphatic ones etc. leave hydrocarbons undissolved.
Example: 100 kg of mineral oil distillate are mixed with 100 kg of aniline. Here, two layers are formed, of which the upper one is a light, refined oil that mimics
Distilling off the last aniline residues yields about 92 kg of finished product.
