  Verfahren zur Herstellung von Leim aus Hornsubstanz. 



   Es ist bereits bekannt, aus Hornsubstanzen durch längeres Erhitzen mit Wasser im Autoklaven bei Temperaturen bis   1200   C und darüber Leim zu gewinnen. 



   Da hierbei die Hornsubstanz in Lösung gebracht wird, muss der Leimbestandteil gefällt und dadurch gereinigt werden. Ausserdem verlangt die Leimgewinnung auf-diesem Wege die Einwirkung des Wassers in mehreren Verfahrensgängen, eine Apparetur von grossen Abmessungen und das Ausscheiden der lästigen, erheblichen Wassermengen. 



   Demgegenüber liegt das wesentliche Kennzeichen des vorliegenden Verfahrens darin. dass die Hornsubstanz allein-also ohne   Wasserzusatz-längerem Erhitzen   auf eine Temperatur über   2000   C im Autoklaven ausgesetzt wird. Es entfallen somit die durch den   bisher üblichen   Wasserzusatz bedingten Nachteile. 



   Die Leimgewinnung erfolgt in einem einzigen Arbeitsvorgang, die hierzu erforderliche Apparatur wird kleiner, die lästigen grossen Wassermengen entfallen und das Erzeugnis kann für viele Zwecke, beispielweise als Zusatz für Tüncherfarbe durch Behandlung mit heissem Wasser in Lösung gebracht, unmittelbar, d. h. ohne es vorher reinigen zu müssen, verwendet werden. 



   Insbesondere geht das Verfahren so vor sich, dass Hornsubstanz wie Klauen, Krallen, Nägel, Hörner, Haare, Federn, Wolle u. dgl. nach Entfernen grober Verunreinigungen im Autoklaven drei Stunden lang auf   2500 C   erhitzt werden. Hierbei können der Hornsubstanz auch Chemikalien in trockener Form, z. B. sauer oder alkalisch reagierende Salze, zugesetzt werden.

  Process for the production of glue from horny substance.



   It is already known to obtain glue from horny substances by prolonged heating with water in an autoclave at temperatures of up to 1200 ° C. and above.



   Since the horny substance is brought into solution here, the glue component has to be precipitated and thereby cleaned. In addition, the glue production in this way requires the action of the water in several process steps, an apparatus of large dimensions and the removal of the annoying, considerable amounts of water.



   On the other hand, the main characteristic of the present proceedings lies in this. that the horny substance alone - i.e. without the addition of water - is subjected to prolonged heating to a temperature above 2000 C in the autoclave. The disadvantages caused by the usual addition of water are thus eliminated.



   The glue is obtained in a single operation, the equipment required for this is smaller, the annoying large amounts of water are eliminated and the product can be dissolved directly for many purposes, for example as an additive for whitewash paint by treatment with hot water. H. without having to clean it beforehand.



   In particular, the procedure is such that horny substance such as claws, claws, nails, horns, hair, feathers, wool and the like. Like. After removing coarse impurities in the autoclave are heated to 2500 C for three hours. Here, the horny substance can also contain chemicals in dry form, e.g. B. acidic or alkaline reacting salts are added.
