Description

Verfahren zur Gewinnung von Zucker aus Melasse Es wurde gefunden, daß man einen großen Teil des Zuckergehaltes der Melasse für sich gewinnen kann, wenn man die Melasse in trockenem Zustand, zweckmäßig bei erhöhter Temperatur, in so viel Methanol aufnimmt, daß sich eine vollständige Lösung ergibt, der Lösung geringe Mengen Schwefeldioxyd und Schwefelsäure zusetzt, sie einige Zeit bei gewöhnlicher, erniedrigter oder erhöhter Temperatur sich selbst überläßt und den aus der Lösung auskristallisierten Zucker von der Flüssigkeit trennt. Zweckmäßig arbeitet man so, daß man die getrocknete Melasse mit heißem Methanol verrührt und in die Flüssigkeit nach dem Erkalten Schwefeldioxydgas einleitet und die Schwefelsäure zugibt. Läßt man dann das Gemisch noch einen oder mehrere Tage stehen, wobei man es auch umrühren kann, und schleudert den abgeschiedenen Zucker ab, so erhält man den überwiegenden Teil des ursprünglich in der Melasse enthaltenen Zuckers.Process for obtaining sugar from molasses It has been found that you can win a large part of the sugar content of the molasses for yourself, if the molasses in the dry state, expediently at an elevated temperature, in absorbs so much methanol that a complete solution results, the solution add small amounts of sulfur dioxide and sulfuric acid, for some time with ordinary, low or high temperature leaves itself and the out of solution separates crystallized sugar from the liquid. One works appropriately that the dried molasses is stirred with hot methanol and poured into the liquid after cooling, introduces sulfur dioxide gas and adds sulfuric acid. Leaves you then stand the mixture for one or more days, while also stirring it can, and if the separated sugar is thrown off, the majority is obtained Part of the sugar originally contained in molasses.

Da die Melasse alkalisch ist und ein Teil des Schwefeldioxyds durch das Alkali gebunden wird, so empfiehlt es sich, wenn man Schwrefeldioxyd und Schwefelsäure sparen will, die Melasse zunächst durch Zusatz anderer Säuren zu neutralisieren. Hierzu läßt sich auch Kohlensäure verwenden; man kann beispielsweise kohlendioxydhaltige Abgase in das Gemisch einleiten.Because the molasses is alkaline and some of the sulfur dioxide through the alkali is bound, so it is advisable to use Schwrefeldioxyd and sulfuric acid wants to save by first neutralizing the molasses by adding other acids. Carbon dioxide can also be used for this purpose; you can, for example, carbon dioxide-containing Introduce exhaust gases into the mixture.

Beispiel 5oo Teile getrocknete Melasse und 3oo Teile Methanol werden unter Erwärmen verrührt. Man läßt abkühlen, leitet 5 Teile Schwefeldioxyd ein, gibt io Teile g6°Joige Schwefelsäure zu und läßt 24 Stunden stehen. Durch Abschleudern erhält man 215 Teile Zucker.Example 500 parts of dried molasses and 300 parts of methanol are used stirred while heating. One lets cool conducts 5 parts of sulfur dioxide a, add 10 parts of g6 ° Joige sulfuric acid and leave to stand for 24 hours. By throwing it off 215 parts of sugar are obtained.
