Description
Verfahren zur Gewinnung von reinem Alkohol Die Erfindung nach dem Hauptpatent 835 735 besteht darin, im AnschluB an die Entgeistung der Maische den gewonnenen Alkohol in einer an sich bekannten Rektifizierkolonne in zwei Fraktionen zu zerlegen und den vorgereinigten, am oberen' Teil der Kolonne abgezogenen Äthvlalkohol bei einem Vorlaufabzug von 15 bis 40-/o in einer oder unter Umständen zwei indirekt beheizten Nachkochkolonnen zu destillieren und in dieser Kolonne jeweils eine Vorlaufmenge von 15 bis 25o/. abzuziehen. Um auch die letzten Spuren geschinackfremder Stoffe aus dem Primasprit zii entfernen, sollen nach dem Hauptpatent in den unteren Destillationsraum der Nachkochkolonne geeignete absorbierende oder sonstige verbessernde Stoffe, wie z. B. nichtflüchtige Säure, z. B. Weinsäure, Citronensäure oder Silberwolle, Aktivkohle, Kieselsäurepräparate od. dgl., eingefüllt werden.Process for the production of pure alcohol The invention according to the Main patent 835 735 consists in the connection to the de-spiriting of the mash recovered alcohol in a known rectifying column in two fractions to disassemble and the pre-cleaned ethyl alcohol withdrawn from the upper part of the column with an advance deduction of 15 to 40- / o in one or, under certain circumstances, two indirectly To distill heated post-boiling columns and in each case a feed amount in this column from 15 to 25o /. deduct. About the last traces of foreign substances Remove from the primate fuel zii, should according to the main patent in the lower distillation room the post-boiling column suitable absorbing or other improving substances, such as z. B. non-volatile acid, e.g. B. tartaric acid, citric acid or silver wool, activated carbon, Silicic acid preparations or the like., Are filled.
Die vorliegende Erfindung bezweckt eine weitere Vervollkommnung des letzten Verfahrens, und zwar dadurch, daB in die Nachkochkolonne Natriumäthylat oder Kaliumäthylat eingeführt wird, ferner ein konstanter oder periodischer Zusatz von Kaliumpermanganat, in Alkohol gelöst, erfolgt. Zusätze von 2o kg Natriumäthylat bzw. Kaliumäthylat genügen für eine Betriebszeit von etwa 14 Tagen. Der Schlamm wird dann abgelassen, und neue Zusätze erfolgen. Von Kaliumpermanganat genügt eine Menge von i kg auf 5ocbm Alkohol, und zwar wird dieser Stoff am unteren Teil der Kolonne zugeleitet.The present invention aims to further improve the last process, namely by adding sodium ethylate to the post-boiling column or potassium ethylate is introduced, furthermore a constant or periodic addition of potassium permanganate dissolved in alcohol. Additions of 20 kg of sodium ethylate or potassium ethylate suffice for one Operating time of about 14 days. The sludge is then drained and new additions are made. From potassium permanganate an amount of 1 kg to 5 ocbm of alcohol is sufficient, and this substance is at the bottom Part of the column fed.
Um eine bessere Durchsetzung der Reinigungszusätze mit dem Alkohol zu erzielen, mu13 der Alkoholzulauf unten angebracht werden, während der Abzug etwas höher, und zwar bis in die Nlitte des Kolonnenaufsatzes zu verlegen ist.To better enforce the cleaning additives with the alcohol In order to achieve this, the alcohol inlet must be placed at the bottom, while the outlet somewhat higher, up to the middle of the column head.
Durch die neuartige Nachbehandlung ergibt sich eine Verbesserung der Permanganat- und Aldehydzahl sowie eine Zerstörung der spezifischen Geschrriacksstoffe, so daB ein reiner Primasprit anfällt.The novel after-treatment results in an improvement in the Permanganate and aldehyde number as well as a destruction of the specific flavorings, so that a pure primate fuel is obtained.
