Description
Verfahren zur Reinigung von organischen Flüssigkeiten Bei der katalytischen Hydrierung der Oxyde des Kohlenstoffs können unter gewissen Bedingungen statt oder neben Methanol verschiedene andere sauerstoffhaltige oder auch sauerstofffreie organische Verbindungen erhalten werden. Beispielsweise können solche sauerstoffhaltigen Verbindungen erhalten werden, wenn man Gemische von Wasserstoff und den Oxyden des Kohlenstoffs, die in bezug auf die für die Gewinnung von Methylalkohol berechnete Menge einen Überschul3 an Wasserstoff enthalten, mit geringerer Strömungsgeschwindigkeit über den Katalysator leitet, als sie für die Bildung eines hauptsächlich Methylalkohol enthaltenden Produktes erforderlich ist. Die hierbei erhaltenen Produkte enthalten, wie sich gezeigt hat, mitunter Verunreinigungen, die beim Gebrauch störend wirken.Process for cleaning organic liquids In the case of catalytic Hydrogenation of the oxides of carbon can take place or under certain conditions In addition to methanol, various other oxygen-containing or oxygen-free organic ones Connections are obtained. For example, such oxygen-containing compounds obtained by using mixtures of hydrogen and the oxides of carbon, the amount calculated in relation to the amount calculated for the production of methyl alcohol Contain excess hydrogen, with a lower flow rate over the catalyst conducts as it is responsible for the formation of a mainly methyl alcohol containing product is required. The products obtained in this way contain As has been shown, sometimes impurities that have a disruptive effect during use.
Es hat sich nun gezeigt, daß man diese Verunreinigungen in einfacher Weise beseitigen kann, wenn man die genannten Produkte mit Basen oder basisch wirkenden Mitteln behandelt. Schon beim bloßen Zusammenbringen mit Soda, Kalk u. dgl. bei gewöhnlicher Temperatur vollzieht sich eine in der Regel ausreichende Reinigung, doch wird diese noch zuverlässiger und rascher erreicht, wenn man die verunreinigten Produkte mit den Basen oder basisch wirkenden Stoffen in der Wärme behandelt, z. B. über Soda oder Kalk, Kreide usw. destilliert.It has now been shown that these impurities can be easily removed Wise can eliminate, if you use the products mentioned with bases or basic acting Means treated. Even with the mere combination with soda, lime and the like cleaning is usually sufficient at normal temperature, but this is achieved even more reliably and more quickly when one is contaminated Products with the bases or substances with a basic effect treated in the heat, e.g. B. distilled over soda or lime, chalk, etc.
Selbstverständlich lassen sich auch einzelne Fraktionen der genannten Hydrierungsprodukte der Oxyde des Kohlenstoffs in .der angegebenen Weise reinigen.Of course, individual fractions of the named Purify hydrogenation products of the oxides of carbon in the manner indicated.
Beispiel z roo Teile der zwischen 105 bis i ro° übergehenden, gelblich gefärbten und terpenartig riechenden Fraktion des Rohöls, das, wie oben angegeben, aus Wasserstoff und den Oxyden des Kohlenstoffs katalytisch hergestellt wurde, werdei mit 2 Teilen gebranntem Kalk destilliert. Man erhält etwa 9o Teile eines wasserhellen Destillats, das einen angenehmen Geruch besitzt.Example z roo parts of the yellowish ones that merge between 105 to i ro ° colored and terpene-like smelling fraction of the crude oil, which, as indicated above, catalytically produced from hydrogen and the oxides of carbon, werdei distilled with 2 parts of quick lime. About 90 parts of a water-white one are obtained Distillate that has a pleasant odor.
Beispiel e roo Teile einer stark gelb gefärbten, unangenehm riechenden Fraktion mit den Siedegrenzen 105 bis i io° des in Beispiel i erwähnten Rohöls werden nach Zusatz von 5 Teilen calc. Soda 5 Stunden unter Rückfluß gekocht und dann destilliert. Man erhält 88 Teile eines Kondensats, das sich durch Farblosigkeit und angenehmen Geruch auszeichnet.Example e roo parts of a strongly yellow-colored, unpleasant smelling fraction with boiling points of 105 to 10 ° of the crude oil mentioned in example i are calc. After addition of 5 parts. Soda boiled under reflux for 5 hours and then distilled. 88 parts of a condensate are obtained, which is characterized by colorlessness and a pleasant odor.
Man hat bereits rohen Holzgeist gereinigt, indem man ihn mit Wasser verdünnte, danach über Kalk destillierte, mit schwachen Oxydationsmitteln behandelte, über Kohle filtrierte und sodann in Kolonnenapparaten fraktioniert destillierte. Im vorliegenden Falle handelt es sich jedoch um die Reinigung anderer Produkte, nämlich der bei der katalytischen Hydrogenisation der Oxyde des Kohlenstoffs entstehenden Gemische, wobei Verunreinigungen gänzlich anderer Art zu entfernen' sind ürid@ züdxn eine wesentlich einfachere Arbeitsweise zum Ziele führt.One has already purified raw wood spirit by washing it with water diluted, then distilled over lime, treated with weak oxidizing agents, filtered through charcoal and then fractionally distilled in column apparatus. In the present case, however, it concerns the cleaning of other products, namely that produced by the catalytic hydrogenation of the oxides of carbon Mixtures, where To remove impurities of a completely different kind ' are ürid @ züdxn a much simpler way of working leads to the goal.
