Description

Verfahren zum Gewinnen von Glycerin aus auf Glycerin vergorenen kohlehydrathaltigen Flüssigkeiten Das Hauptpatent 66¢ 576 betrifft ein Verfahren zum Gewinnen von Glycerin aus auf Glycerin vergorenen k ohlehydrathaltigen Flü,ssigkeiten, insbesondere Dickschlempe oder Melasse, welches darin besteht, daß man die gesamten Gärungserzeugnisse durch Zusatz von Kolloiden organischer oder anorganischer Art in feste Massen überführt und aus diesen sodann das Glycerin durch Lösungsmittel extrahiert. Als kolloide Stoffe kommen bei dieser Arbeitsweise z. B. Kieselgur, Kieselkreide, aktive Kohle, Sägemehl, Torf, Lignin, Bleicherden u. dgl. Stoffe zur Anwendung. Als Lösungsmittel für Glycerin sind Alkohole, Ketone oder Ester genannt.Process for obtaining glycerine from carbohydrate-containing substances fermented on glycerine Liquids The main patent 66 [576] relates to a process for obtaining glycerine from liquids containing carbohydrates fermented on glycerine, especially thick liquor or molasses, which consists in going through all of the fermentation products Addition of colloids of organic or inorganic type converted into solid masses and from these then the glycerol is extracted by solvent. As a colloid Substances come in this way of working z. B. kieselguhr, chalk, active charcoal, Sawdust, peat, lignin, bleaching earth and similar substances are used. As a solvent alcohols, ketones and esters are named for glycerine.

Bei der weiteren Ausgestaltung dieser Erfindung wurde nun gefunden, daß man für die Extraktion des Glycerins aus den genannten festen Massen außer Alkoholen, Ketonen oder Estern auch Äther und deren Derivate als Lösungsmittel verwenden kann. Als solche können z. B. einfache oder gemischte Äther der aliphatischen Reihe, wie Äthyl-, Butyl-, Amyläther, Methyläthyläther, MethylterL-, Butyläther u. dgl., benutzt werden. Ferner können Äther des Glykols oder es Glycerins Anwendung finden. Auch cyclische Äther sind in diesem Fall als Lösungsmittel geeignet.In the further embodiment of this invention it has now been found that for the extraction of glycerol from the solid masses mentioned, apart from alcohols, Ketones or esters can also use ethers and their derivatives as solvents. As such, e.g. B. simple or mixed ethers of the aliphatic series, such as Ethyl, butyl, amyl ethers, methyl ethyl ether, methyl ether, butyl ether and the like will. Ethers of glycol or glycerine can also be used. Even cyclic ethers are suitable as solvents in this case.

Ganz besonders hat sich für die Extraktion des Glycerins das Diäthylendioxyd (Dioxin) bewährt. Die Verwendung dieses Äthers hat den besonderen Vorteil, daß neben dem Glycerin nur ,äußerst geringe Mengen von Fremdstoffen gelöst werden. Beispiel Aus i Teil Kieselgur und 2 Teilen Dickschlempe wird eine- Masse hergestellt, die bei ioo° bis auf einen Gehalt von 3 Q@o`"@V,r. ser getrocknet wird. Die getrocknet wird mit der fünffachen Menge Dio@ gekocht, das Lösungsmittel abgesaügt" die Lösung eingedampft. Nach einer maligen Extraktion mit Diäthylendioxyd ist der größte Teil des Glycerins aus der Masse herausgelöst. Die erhaltenen Extrakte werden durch Destillation weiter gereinigt.Diethylene dioxide (dioxin) has proven particularly useful for the extraction of glycerine. The use of this ether has the particular advantage that, in addition to the glycerine, only extremely small amounts of foreign substances are dissolved. Example A mass is produced from 1 part of kieselguhr and 2 parts of thick stillage which at 100 ° up to a salary of 3 Q @ o` "@ V, r. water is dried. The dried is used with five times the amount of Dio @ boiled, the solvent sucked off " the solution evaporated. After a Extraction with diethylene dioxide removes most of the glycerine from the mass. The extracts obtained are further purified by distillation.
