Description

Die Trennung der neutralen Bestandteile der Teere, Teeröle und Peche von den sauren Anteilen, die hauptsächlich aus phenolartigen Körpern bestehen, erfolgt bisher fast ausnahmslos durch Behandlung mit Natronlauge. The separation of the neutral components of the tars, tar oils and pitches from the acidic ones Shares that mainly consist of phenol-like bodies have so far taken place almost without exception by treatment with caustic soda.

Der Erfindung gemäß wird die gleiche Trennung nach der Erkenntnis vorgenommen, daß durch Ausschütteln oder DurchrührenAccording to the invention, the same separation is made after the knowledge that by shaking or stirring

ίο einer alkoholischen Lösung von paraffinfreien oder paraffinarmen Teeren, z. B. Steinkohlenurteer, deren Teeröfen und Pechen mit Päraffinölen die Neutralöle durch das Paraffinöl aus der alkoholischen Lösung ausgelöst wer - den. Diese Auslösung erfolgt unter Schichtenbildung, wobei die paraffinölhaltige Schicht fast phenolfrei bleibt, während die alkoholische Lösung fast die gesamten sauren öle zurückhält.ίο an alcoholic solution of paraffin-free or low paraffin tars, e.g. B. Coal tar, their tar ovens and pitches with paraffin oils the neutral oils are triggered by the paraffin oil from the alcoholic solution - the. This release takes place with the formation of layers, whereby the paraffin oil-containing layer remains almost phenol-free, while the alcoholic solution contains almost all of the acidic oils holding back.

äo An Stelle des Paraffinöls kann man auch jedes andere hauptsächlich Kohlenwasserstoffe der Paraffinreihe enthaltende Öl, wie z. B. Petroleumdestillate, anwenden. An Stelle aes Äthylalkohols kann man auch andereäo Instead of paraffin oil you can also any other oil containing mainly paraffin series hydrocarbons, such as z. B. Petroleum distillates apply. Instead of ethyl alcohol one can also use other

as organische Lösungsmittel oder Gemische davon verwenden, die ein starkes Lösungsvermögen für Phenole besitzen und mit Paraffinöl oder dem paraffinölhaltigien Lösungsmittel nicht mischbar sind, z. B. Holzgeist, Aceton as organic solvents or mixtures thereof, which have a strong dissolving power for phenols and which are immiscible with paraffin oil or the solvent containing paraffin oil, e.g. B. wood spirit, acetone

u. dgl., ferner Mischungen von Alkohol und Benzol oder Tetrachlorkohlenstoff o. dgl.and the like, also mixtures of alcohol and benzene or carbon tetrachloride or the like.

Die Wahl des paraffinhaltigen Öls richtet sich zweckmäßig nach dem Verwendungszweck, dem die isolierten Neutralöle zugeführt werden sollen.The choice of paraffin-containing oil depends on the intended use, to which the isolated neutral oils are to be fed.

Das' Ausrühren kann auch unter Anwendung der dampfförmigen Phasen oder in der Wärme oder unter Druck erfolgen.Stirring can also be carried out using the vaporous phases or in the heat or under pressure.

Es empfiehlt sich auch, nach beendeter Ausschüttlung mit Paraffinöl, die nach Bedarf wiederholt werden kann, zur Vervollständigung der Trennung der alkoholischen Phenolschicht einige Prozent Wasser zuzusetzen und das Gemisch nochmals gut durchzuschütteln. Dadurch werden die geringen, in der alkoholischen Lösung zurückgehaltenen Anteile von Paraffinöl und anderen Neutralölen weiter ausgeschieden. Es bleibt dann eine neutralölfreie Lösung der Phenole zurück, aus der diese durch Ab destillieren des Lösungsmittels gewonnen werden können.It is also advisable to use paraffin oil after the extraction is complete, as required can be repeated to complete the separation of the alcoholic phenolic layer add a few percent water and shake the mixture well again. This eliminates the minor ones in the alcoholic solution retained portions of paraffin oil and other neutral oils further eliminated. A neutral oil-free solution of the phenols then remains which can be obtained by distilling off the solvent.

Die vereinigten Neutralölschichten können mit einem Gewichtsteü Wasser 1- bis 2naal gewaschen und sodann durch Abdestillieren von paraffinölhaltigen Lösungsmitteln befreit werden, falls nicht das Gemisch unverändert weiter benutzt werden soll. Das paraffinölhaltige Lösungsmittel kann auch für weitere Trennungsoperationen benutzt werden.The combined neutral oil layers can be 1 to 2naal with one part by weight of water washed and then freed from solvents containing paraffin oil by distilling off if the mixture is not to be used unchanged. The paraffin oil containing Solvent can also be used for further separation operations.
