  Verfahren zur Ausscheidung von Nichtzucker aus Zuckerlösungen. 



   Nachdem der   Robsaft   mit irgend einem geeigneten Schwermetallsulfate wie z. B. Ferrooder Zinksulfat auf bekannte Art behandelt oder durch Kalken und Saturationen mit Kohlensäure in üblicher Weise gereinigt wurde, wird auf die in der Art gereinigte Zuckerlösung,   Metatlsulndo   unter den angegebenen näheren Umständen einwirken gelassen, um die gebundenen Oxide der Schwermetalle, welche in der Zuckerlösung aufgelöst zurückbleiben und die   Zuckerlösungen   verunreinigen, in unlösliche   Metallsulfide   zu überführen, und ihre Ausscheidung samt organischen Nichtzuckerstoffen durch Filtration zu erzielen. 



   Dies geschieht entweder durch den Zusatz eines geeigneten Schwefelantimonsalzes in Gegenwart von Kalkhydrat in beliebige Gemische mit   löslichen     Metallsulfiden,   wie z. B. Schwefelkalzium oder Magnesiumsulfid oder aber durch das Vermischen irgend eines reaktionsfähigen   Mctallsulfides beziehungsweise Metallpolysulfides iu   Gegenwart von Kalziumhydroxyd und Saturation mit Kohlensäure oder schwefeliger Säure und darauffolgendem Aufwärmen auf   85 - 9 50 C   und Abfiltrieren. 



   Die Behandlung der nach dem obgenannten bekannten Verfahren gereinigten Säfte mit Metallsulfiden bewirkt die Ausscheidung weiterer wesentlicher Menge von Nichtzuckerstoffen, mithin eine bedeutende Erhöhung des Reinheitsquotienten.

  Process for excretion of non-sugar from sugar solutions.



   After the rob juice has been mixed with any suitable heavy metal sulfate such as B. Ferro or zinc sulphate treated in a known way or cleaned by lime and saturation with carbonic acid in the usual way, is allowed to act on the purified sugar solution, Metatlsulndo under the specified more detailed circumstances, to remove the bound oxides of the heavy metals which are in the sugar solution Remain dissolved and contaminate the sugar solutions, convert them into insoluble metal sulfides, and achieve their elimination, including organic non-sugars, by filtration.



   This is done either by adding a suitable sulfur antimony salt in the presence of hydrated lime in any mixture with soluble metal sulfides, such as. B. calcium sulphide or magnesium sulphide or by mixing any reactive metal sulphide or metal polysulphide in the presence of calcium hydroxide and saturation with carbonic acid or sulphurous acid and subsequent warming to 85-95 ° C and filtering off.



   The treatment of the juices purified by the above-mentioned known process with metal sulfides causes further substantial amounts of non-sugar substances to be eliminated, and consequently a significant increase in the purity quotient.
