Description

Verfahren zum Destillieren von nikotinhaltigen Flüssigkeiten. Gegenstand der Erfindung ist eine Abänderung des Verfahrens des Hauptpatents 319846, welche es ermöglicht, das Nikotin als freie Base zu gewinnen.Process for distilling nicotine-containing liquids. object of the invention is a modification of the method of main patent 319846, which it enables the nicotine to be obtained as a free base.

Bei dem Verfahren des Hauptpatents wird das Nikotin aus den nikotinhaltigen Dämpfen am zweckmäßigsten dadurch gewonnen, daß man die Dämpfe in geeignete Säuren (Schwefelsäure, Oxalsäure usw.) einleitet und die gebildeten Nikotinsalze in üblicher Weise isoliert. Die Gewinnung der freien Base würde mit erheblichen Schwierigkeiten verknüpft sein.In the process of the main patent, the nicotine is derived from the nicotine-containing ones Vapors are most expediently obtained by converting the vapors into suitable acids (Sulfuric acid, oxalic acid, etc.) and the nicotine salts formed in the usual way Way isolated. Obtaining the free base would involve considerable difficulty be linked.

Gegenstand der Erfindung ist nun ein Verfahren, das es in einfachster Weise ermöglicht, das Nikotin sofort in Form der freien Base zu erhalten.The invention is now a method that it is in the simplest Way makes it possible to get the nicotine immediately in the form of the free base.

Zu diesem Zweck wird in der Weise gearbeitet, daß man in das Schlangenrohr des im Hauptpatent beschriebenen Apparates durch das Dampfzuführungsrohr in geeigneter Weise, z. B. mittels einer Pumpe, nacheinander kleine Mengen --eines flüchtigen, mit Wasser nicht mischbaren Lösungsmittels für Nikotin, wie z. B. Petroleumäther, einführt. Der Wasserdampf kann wie bei dem Verfahren des Hauptpatents entweder in das Schlangenrohr oder in den Mantel oder auch in beide eingeführt werden. Das Lösungsmittel wird zum Verdampfen gebracht, so daß durch die Dampfableitung des Schlangenrohres ein Gemisch von Nikotin, Wasser und Lösungsmittel in Dampfform entweicht.For this purpose one works in such a way that one goes into the snake tube of the apparatus described in the main patent through the steam supply pipe in a suitable manner Way, e.g. B. by means of a pump, successively small amounts - a volatile, water-immiscible solvent for nicotine, such as. B. petroleum ether, introduces. The water vapor can, as in the process of the main patent, either in the coiled pipe or the jacket or both. The solvent is made to evaporate, so that through the vapor discharge of the coiled pipe a mixture of nicotine, water and solvent escapes in vapor form.

Wenn man dieses Dampfgemisch derart durch eine geeignete Kühlvorrichtung hindurchgehen läßt, daß die Dämpfe kondensiert werden, so trennen sich das Wasser und der Petroleumäther oder das sonstige geeignete Lösungsmittel, welches letztere das Nikotin aufnimmt, so daß dieses beim Verdunsten des Lösungsmittels als freie Base mit einem Gehalt von etwa go bis 95 Prozent zurückbleibt.If this vapor mixture is allowed to pass through a suitable cooling device in such a way that the vapors are condensed, the water and the petroleum ether or other suitable solvent, which the latter absorbs the nicotine, separate so that this as a free base with a Salary of about go to 95 percent remains.
