Patentirt im Deutschen Reiche vom 27. März 1900 ab.Patented in the German Empire on March 27, 1900.
Beim "Bleisaccharat-Verfahren auf nassem Wege mittelst Bleicarbonat und Alkali ist es von Vortheil, das Bleicarbonat möglichst mit Kohlensäure gesättigt anzuwenden.With the "lead saccharate method on wet By means of lead carbonate and alkali, it is advantageous to use lead carbonate as well as possible Use saturated carbon dioxide.
Wird Bleisaccharat . mit Kohlensäure behandelt, so wird zuerst der Zucker frei gemacht und ist lange schon vollständig in Lösung, bevor das Bleicarbonat gesättigt ist. Bei dem letzten Theil der Saturation gehen dann nach dem Zucker organische und anorganische Verunreinigungen heraus, welche das Filtriren des Carbonats und die Verarbeitung der erhaltenen Zuckerlösung erschweren.Becomes lead saccharate. Treated with carbonic acid, the sugar is first released and is completely in solution long before the lead carbonate is saturated. In the last part of saturation, organic and inorganic follow the sugar Impurities, which the filtration of the carbonate and the processing complicate the obtained sugar solution.
Wir haben gefunden, dafs sich der Vortheil . eines hochgesättigten Bleicarbonats erzielen läfst, ohne die Reinheit der erhaltenen Zuckerlösung zu beeinträchtigen, wenn man die Saturation theilt, also zunächst, wie früher (vgl. Patentschrift 85024, Seite 3) beschrieben, gerade bis zum vollständigen Freiwerden des Zuckers saturirt, das Carbonat durch Filtriren und Auswaschen vom Zucker befreit, mit viel Wasser aufrührt und — am besten in der Wärme — mit Kohlensäure bis zur Sättigung behandelt. Dabei werden auch die durch Wasser allein nicht völlig zersetzlichen Doppelverbindungen des Bleicarbonats mit Alkali zersetzt und das Alkali in Lösung übergeführt, was insbesondere für die Wiederbenutzung des aus der Lauge gefällten Bleicarbonats in Betracht kommt.We have found the advantage. of a highly saturated lead carbonate runs without affecting the purity of the sugar solution obtained, if one has the saturation divides, so initially, as described earlier (see patent specification 85024, page 3), straight until the sugar is completely free, the carbonate is saturated by filtration and washing, freed from the sugar, stirred up with plenty of water and - ideally in the Heat - carbonated to saturation. The Water alone does not decompose completely decomposable double compounds of lead carbonate with alkali and the alkali converted into solution, which is particularly important for the reuse of the lead carbonate precipitated from the liquor comes into consideration.
Mit dieser Nachsaturation läfst sich zweckmäfsig eine Reinigung des Bleicarbonats von aufgenommenem kohlensaurem Kalk verbinden, indem man allmählich während der Zuführung der Kohlensäure einen Ueberschufs der auf den vorhandenen kohlensauren Kalk berechneten Menge Salzsäure oder einer anderen Säure verdünnt zugiebt; dabei geht Blei, nur spurenweise in Lösung.This post-saturation can be expedient Connect a purification of the lead carbonate of ingested carbonate of lime by gradually increasing during the feeding the carbonic acid an excess of that calculated on the existing carbonic acid lime Diluted amount of hydrochloric acid or another acid is added; this goes lead, only traces in solution.
