Description

Verfahren zum praktisch vollkommenen Befreien des absoluten Alkohols von Verunreinigungen Das Filtrieren von Branntwein durch Kohle ist z. B. aus Maercker-Delb r ü c k, Handbuch der Spiritus-Fabrikation, <g. Auflage, S. 552, bekannt. Dabei handelt es sich um einen mit Wasser auf 4o bis 5o Raumhundertteile verdünnten Sprit und immer nur um das Entfernen der in ihm als natürliche Begleitstoffe vorhandenen Verunreinigungen.Process for the practically complete liberation of absolute alcohol of impurities. The filtering of brandy through charcoal is z. B. from Maercker-Delb r ü c k, manual of the alcohol fabrication, <g. Edition, p. 552, known. Included it is a fuel diluted with water to 4o to 5o volume parts and always only about the removal of the natural accompanying substances present in it Impurities.

Nun enthält bekanntlich der absolute Alkohol, dessen Wassergehalt sich nach dem heutigen Stande der Technik bis auf o,2 Prozent herabsetzen läßt, neben Verunreinigungen der vorgenannten Art auch geringe Mengen der zum Zwecke der Wasserentziehung zugesetzten Stoffe, wie z. B. Kalk, Benzol, Benzin u. dgl., die höchstens o,5 Prozent betragen und deren Vorhandensein von dem jeweilig benutzten Herstellungsverfahren abhängt und deren Entfernung große Schwierigkeiten bot.It is well known that absolute alcohol contains its water content can be reduced to 0.2 percent according to the current state of the art, In addition to impurities of the aforementioned type, small amounts of the for the purpose of Dehydration added substances, such as. B. lime, benzene, gasoline and the like at most 0.5 percent and their presence from the respective used Depends on the manufacturing process and its removal posed great difficulties.

Obwohl diese Verunreinigungen in dem absoluten Alkohol nur als Spuren vorhanden sind, machen sie sich doch bei manchen Verwendungszwecken, wie z..B. bei gewissen medizinischen sowie chemischen Zwecken, störend bemerkbar, und es ist daher erforderlich, auch diese Spuren restlos zu entfernen.Although these impurities in the absolute alcohol are only traces are available, they make themselves for some purposes, such as z..B. at certain medical as well as chemical purposes, disturbing noticeable, and it is therefore necessary to completely remove these traces as well.

Dies geschieht gemäß der Erfindung dadurch; daß man den absoluten Alkohol durch Kohle filtriert. Überraschenderweise reinigt nämlich die Kohle den wasserfreien Alkohol von den zur Herstellung verwendeten Zusatzstoffen, wie Kalk, Benzin, Benzol u. dgl., und entfernt zugleich auch noch vorhandene, aus dem Sprit herrührende natürliche Begleitstoffe.According to the invention, this is done by; that you get the absolute Alcohol filtered through charcoal. Surprisingly, the coal cleans the anhydrous alcohol from the additives used in production, such as lime, Petrol, benzene and the like, and at the same time removes any still existing ones from the fuel natural accompanying substances.

Zu dem Zweck, das zur Wasserentziehung vorher zugesetzte Benzol aus dem absoluten Alkohol restlos zu entfernen, hat Y o u n g vorgeschlagen, ihn nachträglich nochmals mit Normalhexan zu destillieren, was jedoch umständlich und kostspielig ist. Abgesehen davon ist es aber nicht möglich, durch Destillation mit Normalhexan auch die Verunreinigungen zu entfernen, die als natürliche Begleitstoffe sogar noch in dem absoluten Alkohol zurückbleiben.For the purpose of removing the previously added benzene for dehydration To remove the absolute alcohol completely, Y o u n g suggested it afterwards to distill again with normal hexane, which, however, is laborious and expensive is. Apart from that, however, it is not possible by distillation with normal hexane also remove the impurities that are even considered natural accompanying substances remain in the absolute alcohol.

Das neue Verfahren bietet also vor allem den Vorteil, daß man in ganz besonders einfacher Weise V erunrednigungen der beiden oben angeführten Arten aus dem absoluten Alkohol entfornen kanw: °° 1`@n weiterer, für die Praxis gleichfalls .sehr bedeutungsvoller Vorteil des netten- Verfahrens besteht darin, daß man bei der Wasserentziehung von Rohsprit ausgehen kann.The main advantage of the new process is that it can be used in whole in a particularly simple way defamation of the two above Unform species from absolute alcohol kanw: °° 1` @ n further, for practice Likewise, a very significant advantage of the nice method is that that you can start with raw fuel when dehydrating.
