  Verfahren zar Entfärbung von Flüssigkeiten. 



   Zur Entfärbung und Klärung von Flüssigkeiten, wie Fetten, Ölen, Zuckerlösungen u.dgl., verwendet man verschiedene Kohlenarten, Russ, kalzinierten Russ, besondere Entfärbungskohlen, die unter den   Namen Carboraffin. Norit.   Eponit u. dgl, bekannt sind, welche Stoffe durch besondere Behandlung wirksam gemacht werden. 



   Es wurde nun gefunden, dass sich für die angegebenen Zwecke ein Russ ganz besonders eignet. der bei der unvollständigen   Verbrennung von Erdgasen, hauptsächlich von Methan,   entsteht und mit Carbon-black bezeichnet wird, vorausgesetzt, dass dieser Carbon-black. wenn er nicht bereits bei der Erzen-

 mittel der   erwähnten   Art. So haben Versuche ergeben, dass unter Annahme der Entfärbekraft von Knochenkohle gleich 1, die Entfärbekraft von gewöhnlichem Russ gleich 0-1, von mit Säure extrahierten Russ gleich 15-20, von hochwertigen Entfärbungskohlen aus Holzkohle etwa gleich 30 und von Cal bonblack aus Erdgas gleich   100--120 ist.   



   Der Carbon-black wird vorzugsweise bei niedrigen Temperaturen zur   Anwendung   gebracht.

  Process for decolorization of liquids.



   To decolorize and clarify liquids such as fats, oils, sugar solutions and the like, various types of charcoal are used, carbon black, calcined carbon black, special decolorizing carbon, which is known as carboraffin. Norit. Eponit u. Like, it is known which substances are made effective by special treatment.



   It has now been found that a carbon black is particularly suitable for the stated purposes. which arises from the incomplete combustion of natural gases, mainly methane, and is referred to as carbon black, provided that this is carbon black. if he is not already at the

 Means of the kind mentioned. Experiments have shown that assuming the decolorizing power of bone charcoal is equal to 1, the decolorizing power of ordinary soot is 0-1, of acid-extracted soot is 15-20, of high-quality decolorizing charcoal is about 30 and from Cal bonblack from natural gas is equal to 100-120.



   The carbon black is preferably used at low temperatures.
