Description
Verfahren zur Reinigung von Ölen. Zur Reinigung von Handelsbenzolen, Erdölprodukten, Braunkohlen- und Steinkohlenurteeren ist bisher vorzugsweise Schwefelsäure oder Aluminiumchlorid verwendet worden. Hierbei gehen die Reinigungsmittel fast völlig verloren, die entfernten Verunreinigungen bilden unverwertbare saure Produkte, die sogenannten »Brandharze«.Process for cleaning oils. For cleaning commercial benzenes, For petroleum products, lignite and hard coal tares, sulfuric acid has so far been preferred or aluminum chloride has been used. Here the detergents almost go completely lost, the removed impurities form unusable acidic products, the so-called "fire resins".
Speziell zur Entschwefelung ist auch vorgeschlagen worden, die Öle mit Metalloxyden oder Hydroxyden unter dem Druck eines Gases, am besten Wasserstoff, zu behandeln (Patentschrift 29o563) oder die Öle mit Metallsulfiden in Reaktion zu bringen, die die Neigung haben, Schwefel aufzunehmen (Patentschrift 380059).The oils have also been proposed specifically for desulphurization with metal oxides or hydroxides under the pressure of a gas, preferably hydrogen, to treat (patent specification 29o563) or the oils with metal sulfides in reaction to bring that have a tendency to absorb sulfur (patent specification 380059).
Es war nicht bekannt, daß es gelingt, Benzole usw. weitgehend zu reinigen, wenn sie ohne Zusatz eines Katalysators mit oder ohne Druck eines Gases, am zweckmäßigsten Luft, kurze Zeit auf höhere Temperatur erhitzt werden. Durch dieses Verfahren wird Polymerisation und Kondensation der ungesättigten Bestandteile bewirkt. Schwefelkohlenstoff und Blausäure werden zerstört.It was not known that it was possible to largely purify benzene etc. when they are most expedient without the addition of a catalyst with or without the pressure of a gas Air, heated to a higher temperature for a short time. Through this procedure, Polymerization and condensation of the unsaturated components causes. Carbon disulfide and hydrogen cyanide are destroyed.
Nach dem Abdestillieren von de;i polyinerisierten Produkten ist der Waschverlust auf ein Drittel bis ein Viertel herabgedrückt. Von allen ungesättigten Teilen werden nur die Thiophene schwieriger angegriffen. Es ist aber zu bemerken, daß diese Verbindungen licht- und luftbeständig sind und nicht verharzen.After the de; i polymerized products have been distilled off, the Wash loss depressed to a third to a quarter. Of all unsaturated Parts only the thiophenes are more difficult to attack. But it should be noted that these compounds are light and air-resistant and do not resinify.
Durch Gegenwart von Wasser, Metallen, \letalh-erbindungen, Säuren und. Alkalien kann man die Art der Polymerisate weitgehend verändern. Von den Polymerisationsrückständen läßt sich durch Destillation unter einer der üblichen Bedingungen ein Teil in flüssiger Form gewinnen. Der Rest ist ein neutrales, stets verwertbares Pech.Due to the presence of water, metals, \ lethal compounds, acids and. Alkalis can largely change the nature of the polymers. From the polymerization residues a part can be converted into liquid by distillation under one of the usual conditions Gain shape. The rest is a neutral, always usable bad luck.
Beispiele. i. Rohbenzol mit einem Waschverlust von .4,65 Prozent wird 2 Stunden unter zo Atm. Druck auf i5o° erhitzt. Das tiefbraune Produkt wird destilliert. Das Destillat hat nur einen Waschverlust von 2,2 Prozent. Die verbleibenden Verunreinigungen Lestehen im wesentlichen au: Thiophen.Examples. i. Crude benzene with a wash loss of .4.65 percent will 2 hours under zo atm. Pressure heated to 150 °. The deep brown product is distilled. The distillate only has a washing loss of 2.2 percent. The remaining impurities Read essentially as follows: thiophene.
2. Dasselbe Rohbenzol wird 2 Stunden unter 75 Atm. Druck auf 2oo° erwärmt. Das gereinigte Öl hat einen Waschverlust von 1,6 Prozent, .der nur aus Thiophen besteht.2. The same crude benzene is under 75 atm for 2 hours. Pressure to 2oo ° warmed up. The cleaned oil has a washing loss of 1.6 percent, the only off Thiophene is made up.
3. Das Rohbenzol wird durch ein auf 300 bis d.00° geheiztes Rohr geleitet. Der Waschverlust im Kondensat ist auf etwa die Hälfte gesunken.3. The crude benzene is passed through a pipe heated to 300 to d.00 °. The washing loss in the condensate has dropped to about half.
In allen Fällen ist kein Schwefelkohlenstoff mehr nachzuweisen. Die so gereinigten Öle zeichnen sich durch größte Beständigkeit gegen Licht und Luft aus und bedürfen in den meisten Fällen der Schwefelsäurewäsche nicht mehr.In all cases no more carbon disulfide can be detected. the Oils cleaned in this way are extremely resistant to light and air and in most cases no longer require sulfuric acid washing.
