Description

Pate ν τ-An SPRU ch:Godfather ν τ-An SPRU ch:

Verfahren zum Reinigen von Knochen für die Leimfabrikation, dadurch gekennzeichnet, daß die gegebenenfalls mit Säuren behandelten Knochen mit verdünntem wäßrigem Ammoniak extrahiert werden.Method for cleaning bones for glue production, characterized in that that the bones, which may have been treated with acids, are extracted with dilute aqueous ammonia will.

Sanqefuqt bet cicnmit imq Sanqefuqt bet cicnmit imq KAISERLICHESIMPERIAL PATENTAMTPATENT OFFICE Die meisten Knochen enthalten außer den anorganischen Bestandteilen und der leimgebenden Substanz Proteinkörper, welche bewirken, daß die aus den Knochen dargestellte Gelatine trüb ist. Diese die Herstellung von Leim oder Gelatine störenden Körper lassen sich aus den Knochen direkt oder nachdem sie zur Entfernung der anorganischen Bestandteile mit Säuren behandelt worden sind, durch Ausziehen mit wäßrigem Ammoniak entfernen, ohne daß hierdurch die leimgebende Substanz zerstört wird. Die so gereinigte Masse gibt dann eine klare Gelatine.Most bones contain inorganic and glue-producing components Substance Protein bodies which cause the gelatin produced from the bones to be cloudy. This the manufacture Disruptive bodies of glue or gelatin can be removed from the bones directly or after they are used to remove the inorganic Components that have been treated with acids can be removed by exhaustion with aqueous ammonia without this the sizing substance is destroyed. The mass cleaned in this way then gives a clear one Gelatin. Dieses Verfahren ist verschieden von dem Verfahren des Patentes 103981, Kl. 12 a, bei welchem nicht Knochen, sondern Leder, und zwar zur Entfernung von Gerbstoff mit starkem Ammoniak unter Druck behandelt wird. Dasselbe gilt bezüglich des in der Patentschrift 100065, Kl. 22, beschriebenen Verfahrens, welches die Gewinnung von Leim aus Leimrohstoffen durch Behandeln der letzteren mit starkem wäßrigem Ammoniak unter Druck bezweckt, während bei dem vorliegenden Verfahren die Leimrohstoffe nicht gelöst, sondern nur gereinigt werden.This method is different from the method of patent 103981, cl. 12 a which not bones, but leather, treated with strong ammonia under pressure to remove tannin will. The same applies to that described in patent specification 100065, class 22 Process which involves the extraction of glue from glue raw materials by treating the latter with strong aqueous ammonia Purpose under pressure, while in the present process the glue raw materials are not dissolved, but only cleaned will. Beispiel: 2 kg mit Säuren von den anorganischen Bestandteilen befreite und mit Wasser ausgewaschene Knochen werden in IO 1 wäßrigem, einprozentigem Ammoniak 2 Tage unter öfterem Umrühren, am besten bei mäßiger Wärme, digeriert. Hierauf wird die trübe Lösung abgegossen, die leimgebende Masse mit Wasser geknetet und ausgewaschen. Example: 2 kg freed from the inorganic components with acids and with Bones washed out with water are best kept in 10 1 aqueous, one percent ammonia for 2 days with frequent stirring in moderate warmth, digested. Then the cloudy solution is poured off, the glue giving Mass kneaded with water and washed out.
