Description

Verfahren zur Reindarstellung von Gelatine. Es ist bisher nur unter Anwendung kostspieliger und zeitraubender Methoden gelungen, eine Gelatine (oder Leim) herzustellen, die möglichst von Verunreinigungen frei ist.Process for the pure preparation of gelatine. It's just under so far Using costly and time-consuming methods, a gelatin (or Glue) that is as free of impurities as possible.

Die Erfindung betrifft ein einfaches und zuverlässiges Verfahren zur Darstellung vollkommen reiner Gelatine (oder Leim) bei gleichzeitiger Erzielung einer ungewöhnlich hohen Ausbeute, so z. B. bei Sehnen bis zu go Prozent. Es besteht darin, daß Sehnen, Knochen, Spaltleimleder oder andere bekannte Ausgangsstoffe einer Behandlung mit wässerigem Chlordioxyd unterworfen werden. Hierbei ergibt sich ein gelatine- (oder leim-) haltiges Material, welches, mit kaltem Wasser ausgewaschen und nachher mit warmem Wasser extrahiert, reine farblose Gelatine (oder Leim) liefert, welche von Verunreinigungen, z. B. färbenden Beimengungen, befreit ist. Diese Wirkung ist darauf zurückzuführen, daß die Verunreinigungen durch die Behandlung mit Chlordioxyd gelöst und durch das Waschwasser restlos entfernt «-erden.The invention relates to a simple and reliable method for Presentation of completely pure gelatin (or glue) with simultaneous achievement an unusually high yield, e.g. B. with tendons up to go percent. It exists in the fact that tendons, bones, split glue or other known raw materials of a Subject to treatment with aqueous chlorine dioxide. This results in a gelatin- (or glue-) containing material which, washed out with cold water and then extracted with warm water, delivers pure colorless gelatin (or glue), which of impurities, e.g. B. coloring additions, is exempt. This effect is due to the fact that the contamination from the treatment with chlorine dioxide dissolved and completely removed by the washing water.

Auch wenn es sich um mit Kalk vorbehandelte Ausgangsstoffe handelt, wie z. B. bei Spaltleimleder, so ergibt sich bei Behandlung nach dem oben angegebenen Verfahren die gleiche Wirkung.Even if the raw materials are pre-treated with lime, such as B. in the case of split glue leather, this results in treatment according to the above Procedure has the same effect.

Beispiel. Man bringt Sehnen in eine wässerige Lösung von Chlordioxyd. Nach Beendigung der Reaktion wäscht man das gelatine- (oder leim-) haltige Material mit kaltem Wasser bis zur neutralen Reaktion aus. Alsdann txtrahiert man mit warmem Wasser die Gelatine (oder Leim). Der Erfolg ist von der Konzentration der Chlordioxydlösung in weiten Grenzen unabhängig.Example. Tendons are placed in an aqueous solution of chlorine dioxide. After the reaction has ended, the material containing gelatin (or glue) is washed with cold water until the reaction is neutral. Then extract with warm Water the gelatin (or glue). The success is from the concentration of the chlorine dioxide solution largely independent.

Um Anhaltspunkte für den Verbrauch von Chlordioxyd anzugeben, seien beispielsweise nachstehende Angaben gemacht: r kg Sehnen erfordert nur etwa 2o bis 40 g Chlordioxyd, oder r kg Spaltleimleder erfordert nur etwa i o g Chlordioxyd.To give clues for the consumption of chlorine dioxide, are For example, the following information is given: r kg of tendons only requires about 2o to 40 g of chlorine dioxide, or r kg of split glue leather, only requires about 10 g of chlorine dioxide.
