Description
Verfahren zur Gewinnung von Phenolen aus Teeren oder Teerölen aller Art. Die vorliegende Erfindung betrifft ein Verfahren zur Gewinnung der Phenole (sauren Öle) aus Teeren und Teerölen aller Art,, z. B. Steinkohlenteeren, Steinkohlenteerölen, Schieferteeren, Schieferteerölen, Braunkohlenteeren, Braunkohlenteerölen, Holzteerölen. Das Verfahren besteht darin, daß man die Teere bzw. Teeröle mit solchen Mengen der wasserlöslichen Salze organischer Basen versetzt, daß eine Ausscheidung der sauren Öle stattfindet. Man kann z. B. die wasserlöslichen Salze anorganischer oder organischer Säuren mit Pyridin oder dessen Homologen oder die Salze der primären, sekundären oder tertiären Amine der aromatischen Reihe oder sekundärer oder tertiärer aliphatischer oder hydroaromatischer Amine verwenden. Die Flüssigkeit trennt sich nach genügendem Zusatz der benannten Stoffe in zwei Schichten, von denen die eine die neutralen Öle, die. andere das Salz und die Phenole enthält;. Man kann die Salze einzelner Basen oder ihrer Gemische verwenden. Es ist nicht notwendig, daß man die Salze in reinem Zustande anwendet; man kann vorteilhaft die Lösung der Basen in Säuren benutzen.Process for obtaining phenols from tars or tar oils of all Art. The present invention relates to a process for the production of the phenols (acidic oils) from tars and tar oils of all kinds, z. B. coal tars, coal tar oils, Shale tars, shale tar oils, lignite tars, lignite tar oils, wood tar oils. The method consists in that the tars or tar oils with such amounts of water-soluble salts of organic bases added that an excretion of the acidic Oils takes place. You can z. B. the water-soluble salts of inorganic or organic Acids with pyridine or its homologues or the salts of the primary, secondary or tertiary amines of the aromatic series or secondary or tertiary aliphatic or hydroaromatic amines. The liquid separates after enough Addition of the named substances in two layers, one of which is the neutral one Oils that. others containing the salt and phenols. One can use the salts individually Use bases or their mixtures. It is not necessary to have the salts in apply in a pure state; the solution of the bases in acids can advantageously be used.
Die Salze können z. B. sein: Sulfate, Chloride, Nitrate, Acetate und Lactate.The salts can e.g. B. be: sulfates, chlorides, nitrates, acetates and Lactates.
Versetzt man z. B. ein Braunkohlenteeröl mit etwa io Prozent einer Mischung von, i Mol. 5ogrädiger Schwefelsäure und z MoI. Pyridinbasen, so tritt eine Abscheidung ein, die bei weiterem Zusatz auf z. B. insgesamt 15 Prozent ihren Höhepunkt erreicht. Beim Stehen trennt sich die Masse in zwei Schichten. In der oberen Schicht findet man nur einen Bruchteil, z. B. io bis 15 Prozent, von der Gesamtmenge der im Öl enthalten gewesenen sauren Bestandteile. Die untere Schicht besteht aus den sauren Ölen und aus Pyridinsulfat. Die beiden Schichten werden voneinander getrennt. Wird die Schicht der sauren Bestandteile mit genügenden Mengen kalten oder warmen Wassers vermischt, z. B. gerührt oder geschüttelt, so geht das Pyridinsulfat in Lösung über, und die Phenole scheiden sich ab. Ihre Menge beträgt z. B. 85 bis 9o Prozent von der Gesamtmenge der in dem Öl ursprünglich vorhanden gewesenen sauren Bestandteile.If you move z. B. a lignite tar oil with about 10 percent of a mixture of, i mol. 5ogrädiger sulfuric acid and z MoI. Pyridine bases, a deposition occurs, which with further addition to z. B. a total of 15 percent peaked. When standing, the mass separates into two layers. In the upper layer there is only a fraction, e.g. B. 10 to 15 percent, of the total amount of the acidic constituents contained in the oil. The lower layer consists of the acidic oils and pyridine sulfate. The two layers are separated from each other. If the layer of acidic components is mixed with sufficient amounts of cold or warm water, e.g. B. stirred or shaken, the pyridine sulfate goes into solution and the phenols separate. Their amount is z. B. 85 to 90 percent of the total amount of acidic components originally present in the oil.
Das Verfahren gestaltet sich im allgemeinen folgendermaßen: Man gibt zu dem Öl eine gewisse Menge eines Gemisches, bestehend aus Basen und Säure. Die erforderliche Menge wird durch Vorversuche mit einer abgemessenen Menge .des zu behandelnden Teers oder Teeröles bestimmt. Man rührt das Gemisch gut durcheinander und läßt es dann absitzen. Nach Verlauf von einigen Stunden trennt sich die Flüssigkeit in zwei Schichten, welche voneinander durch Abziehen getrennt werden. Die erhaltenen neutralen Öle können durch Waschen von den Salzen der Basen befreit werden. Das Waschwasser kann zur Zerlegung der sauren phenolhaltigen Schicht benutzt werden. Die bei dem Zerlegen der die sauren Öle enthaltenden Schicht erhaltene wässerige Lösung der Basensalze kann eingedampft werden und dann weiter zur Gewinnung der Phenole dienen. Zur Ausführung des vorliegenden Verfahrens können die aus dem Steinkohlenteer erhältlichen Basen einzeln oder im Gemisch benutzt werden. Man kann die Salze der primären, sekundären und tertiären Amine der aromatischen Reihe verwenden. Besonders geeignet sind die Pyridinbasen, von denen sowohl die hoch- und niedrigsiedenden verwendet werden können. Zweckmäßig wählt man solche Basen, deren Salze leicht löslich oder schwer kristallisierbar sind. Man kann saure Salze, aber auch neutrale Salze benutzen.The general procedure is as follows: You give to the oil a certain amount of a mixture consisting of bases and acids. the required amount is determined by preliminary tests with a measured amount of .des treating tar or tar oil. The mixture is stirred well together and then let it sit down. After a few hours, the liquid separates in two layers, which are separated from each other by peeling. The received Neutral oils can be freed from the salts of the bases by washing. That Wash water can be used to break down the acidic phenol-containing layer. The aqueous layer obtained by decomposing the acidic oil-containing layer Solution of the base salts can be evaporated and then further used to obtain the Phenols are used. To carry out the present method you can the bases obtainable from coal tar can be used individually or in a mixture. One can use the salts of the primary, secondary and tertiary amines of the aromatic Use row. The pyridine bases are particularly suitable, of which both the high and low boiling points can be used. Appropriately one chooses such Bases whose salts are easily soluble or difficult to crystallize. One can sour Use salts, but also neutral salts.
