Description
In dem Patent 298593 ist ein Verfahren zur Herstellung von Propantriol aus Zucker unter Benutzung einer Gärung in alkalischer Reaktion und Führung der Gärung über die Bildung von 3 Prozent Propantriol berechnet auf Zucker hinaus beschrieben worden.In the patent 298593 is a process for the production of propanetriol from sugar using fermentation in an alkaline reaction and conducting fermentation over the Formation of 3 percent propanetriol calculated on sugar addition has been described.
Es hat sich gezeigt, daß unter den verwendbaren alkalisch reagierenden Verbindungen die Sulfite der Alkalien besonders günstig wirken. Die Ausbeute an Propantriol ist besonders hoch, und die Hefe behält wesentlich längere Zeit als bei anderen Salzen ihre Lebenskraft.It has been found that, among the compounds which can be used, alkaline compounds the sulphites of the alkalis have a particularly favorable effect. The yield of propanetriol is special high, and the yeast retains its vitality much longer than with other salts.
Die günstige Wirkung der- Sulfite war nicht vorauszusagen. Man hat schwefligsaure Salze, unter anderen auch das alkalisch reagierende, neutrale, schwefligsaure Natrium, bei der sauren Alkoholgärung verwendet, um eine möglichst reine Gärung zu erhalten (Maercker, Das Flußsäureverfahren in der Spiritusfabrikation, 1891, S. 15 bis 26). Da aber hierbei die Alkoholausbeute im Vergleich zu der Gärung beim Fehlen der schwefligsauren Salze nicht verringert wurde, sondern gleichblieb (Maercker) oder'sogar stieg (Heinzelmann), so konnte man die Vermehrung der Ausbeute an Propantriol bei der Fortführung der Gärung über die Menge von 3 Prozent Propantriol hinaus nicht annehmen. Mit Rücksicht auf die günstige Wirkung der Sulfite bei der sauren Alkoholgärung konnte man eine besonders günstigeThe beneficial effect of the sulfites could not be predicted. One has sulphurous acid salts, among other things also the alkaline reacting, neutral, sulphurous acid sodium, in the acidic Alcohol fermentation is used to obtain the purest possible fermentation (Maercker, Das Hydrofluoric acid processes in alcohol production, 1891, pp. 15 to 26). But here the alcohol yield in comparison to the fermentation in the absence of the sulphurous acid salts not reduced but stayed the same (Maercker) or even increased (Heinzelmann), so could one can increase the yield of propanetriol when the fermentation continues do not accept the amount beyond 3 percent propanetriol. With consideration for the cheap Effect of the sulphites in the acidic alcohol fermentation one could see a particularly favorable one
Wirkung der Sulfite für die Propantriolgärung nicht erwarten, da erfahrungsgemäß die Summe des bei der Gärung gewonnenen Alkohols plus Propantriols annähernd konstant ist.Do not expect the sulfites to have an effect on propanetriol fermentation, as experience has shown that this is the sum of the alcohol plus propanetriol obtained during fermentation is approximately constant.
Die Ausbeute an Propantriol wächst mit steigendem Sulfitgehalt.The yield of propanetriol increases with increasing sulfite content.
Die Temperatur der Gärung ist vorteilhaft nicht zu niedrig.The fermentation temperature is advantageously not too low.
ι kg Rohzucker, 100 g Natriumsul'fit und 100 g Hefe wird in 6,61 Wasser gebracht und die Flüssigkeit bei 300 gären gelassen. Nachdem der Zucker verschwunden ist oder gegebenenfalls schon vorher, wenn genügend Propantriol gebildet ist (jedenfalls über 3 Prozent des Zuckers), gewinnt man den Alkohol beispielsweise durch Destillation. Die verbleibende Lösung wird mit Entfärbungskohle aufgekocht, filtriert und eingedampft. Der verbleibende Rückstand wird mit Alkohol extrahiert. Nach 'dem Verdampfen des Alkohols gewinnt man 14,3 Prozent Propantriol. Die vorher abdestillierte Menge von Alkohol beträgt 39 Prozent.ι kg raw sugar, 100 g and 100 g Natriumsul'fit yeast is brought into 6.61 of water and the liquid at 30 0 allowed to ferment. After the sugar has disappeared or, if necessary, before, when enough propanetriol has been formed (at least over 3 percent of the sugar), the alcohol is obtained, for example, by distillation. The remaining solution is boiled with decolorizing charcoal, filtered and evaporated. The remaining residue is extracted with alcohol. After the alcohol has evaporated, 14.3 percent propanetriol is obtained. The amount of alcohol previously distilled off is 39 percent.
Wenn man 120 g Sulfit anwendet, so erhält man 16 Prozent Propantriol und 30 Prozent Alkohol. Wenn man 250 g Sulfit anwendet, so erhält man 23,5 Prozent Propantriol und 24 Prozent Alkohol.If you use 120 g of sulfite, you get 16 percent propanetriol and 30 percent alcohol. If you use 250 g of sulfite, you get 23.5 percent propanetriol and 24 percent alcohol.

Zur Isolierung des Propantriols kann man die vergorene Flüssigkeit eventuell entfärben und dann konzentrieren, worauf das Propantriol entweder durch Destillation oder durch Extraktion mit organischen Lösungsmitteln gewonnen wird. Nach dem Abfiltrieren der Hefe kann die vergorene Flüssigkeit mit Kalk,-Eisenverbindungen oder Magnesia o. dgl. zur Entfernung von Verunreinigungen behandelt werden, worauf dann die Konzentration vorgenommen werden kann. An Stelle der Sulfite können auch Verbindungen, welche Sulfite liefern, verwendet Werden.The fermented liquid can be decolorized to isolate the propanetriol and then concentrate on what the propanetriol either by distillation or by Extraction with organic solvents is obtained.

.'.. !Es hat sich gezeigt, daß es vorteilhaft ist, neben Suhlten Salze von reduzierenden Säuren des Schwefels, wie Hydrosulfit, Hyposulfit, Sulfoxylate u. dgl., zu verwenden. Die Gärung verläuft dann günstiger und führt eine Steigerung der Glyzerinausbeute herbei. Das Auftreten von Schwefelwasserstoff oder üblen Gerüchen (Maercker) ist bei dieser Versuchsanordnung niemals zu beobachten. . '...! It has been shown that it is advantageous in addition to Suhlten salts of reducing acids of sulfur, such as hydrosulphite, hyposulphite, Sulfoxylates and the like. The fermentation then proceeds more favorably and leads to a Increase in glycerine yield. The appearance of hydrogen sulfide or foul Odors (Maercker) can never be observed in this test arrangement.
