In dem Patent 298593 ist "ein Verfahren zur Herstellung von Propantriol aus Zucker unter Benutzung einer Gärung in alkalischer In patent 298593 there is "a process for the preparation of propanetriol from sugar using fermentation in alkaline
__ Reaktion und Führung der Gärung über die Bildung von 3 Prozent Propantriol, berechnet auf Zucker, hinaus beschrieben worden. Im allgemeinen steigt die Bildung von Propantriol mit der Stärke der alkalischen Reaktion bzw. der Menge des Zusatzes des alkalisch wirkenden Stoffes. Andererseits geht die Steigerung der Ausbeute an Propantriol nur bis zu einer je nach dem zugesetzten Stoffe schwankenden Grenze, bei deren Überschreitung die Bildung von Propantriol verringert wird und schließlieh aufhören kann. Es hat sich nun gezeigt, daß man ohne Schädigung der Bildung von . Propantriol erheblich größere Mengen alkalisch reagierender Stoffe verwenden kann, wenn man die alkalisch wirkenden Stoffe nicht für sich allein, sondern in Gegenwart von Neutralsalzen des Magnesiums anwendet. Dieser Zusatz wirkt bei den verschiedenen für das Verfahren verwendbaren alkalisch reagierenden Verbindungen vorteilhaft. Besonders vorteilhaft wirken die Zusätze der Salze bei den in dem Patent 298594 zur Erzeugung der alkalischen Reaktion vorgeschlagenen Sulfiten. Während die Bildung von Propantriol im allgemeinen bei einem Zusatz von über 50 Prozent Sulfit, auf Zucker berechnet, aufhört, kann man sogar noch größere Mengen Sulfit in Gegenwart der Salze des Magnesiums anwenden. Man kann beispielsweise Magnesiumsulfat oder Magnesiumchlorid anwenden. Man kann auch organische Salze benutzen. Be-__ reaction and conduct of the fermentation over the Formation of 3 percent propanetriol calculated on sugar has been described. in the In general, the formation of propanetriol increases with the strength of the alkaline reaction or the amount of the addition of the alkaline substance. On the other hand, there is an increase the yield of propanetriol only fluctuates up to a point depending on the substances added Limit, beyond which the formation of propanetriol is reduced and finally can stop. It has now been shown that without damaging the formation of. Propanetriol considerably larger amounts are alkaline reactive substances can be used if one does not use the alkaline substances for used alone, but in the presence of neutral salts of magnesium. This Additive has an effect on the various alkaline reactants that can be used for the process Connections beneficial. The addition of the salts is particularly advantageous for the in sulfites proposed in patent 298594 for generating the alkaline reaction. While the formation of propanetriol generally with an addition of over 50 percent Sulphite, calculated on sugar, stops, you can get even larger amounts of sulphite Apply in the presence of magnesium salts. One can, for example, magnesium sulfate or use magnesium chloride. Organic salts can also be used. Loading
dingung ist selbstverständlich, daß die verwendeten Salze auf das verwendete Ferment nicht giftig wirken.Condition is of course that the salts used are based on the ferment used do not act poisonous.

ι kg Zucker wird in 7 1 Wasser mit 1000 g Magnesiumchlorid und 750 g Natriumbicarbonat in der Kälte aufgelöst und dazu 150 g Hefe gegeben. Dann läßt man das Gemenge bei 30° stehen. Nach kurzer Zeit beginnt die Gärung. Nach zwei Tagen setzt sich die Hefe ab, und Zucker ist in der Flüssigkeit nicht mehr nachzuweisen.

The mixture is then left to stand at 30 °. After a short time it begins the fermentation. After two days the yeast will settle and there will be sugar in the liquid no longer to be proven. 30 percent alcohol and 20 percent propanetriol are obtained sourced the sugar in the processed fermentation liquid.

Nach kurzer Zeit setzt die Gärung ein und ist in 3 bis 5 Tagen beendet. Man erhält hierbei 35 Prozent Propantriol und etwa 6 Prozent Alkohol.

After a short time Fermentation begins and is over in 3 to 5 days. This gives 35 percent propanetriol and about 6 percent alcohol. Without the addition of magnesium acetate, it ferments Approach 4 to 5 days longer.
Magnesiumbicarbonat und MagnesiumsulfitMagnesium bicarbonate and magnesium sulfite
sind in der Flüssigkeit bei Gegenwart von Zucker ziemlich leicht löslich, so daß sich
Niederschläge in der Kälte nicht bilden.
ι Ein besonderer Vorzug der Verwendung der Zusätze Kon 'tMagnesiumsalzen besteht darin,
daß eine nicht unerhebliche Beschleunigung der Gäruäg · stattfindet - und damit der Gärraum
besser ausgenutzt werden kann.are fairly easily soluble in the liquid in the presence of sugar, so that precipitates do not form in the cold.
A particular advantage of using the additives of magnesium salts is that the fermentation process is accelerated to a not inconsiderable extent - and the fermentation space can thus be better utilized.
