  Verfahren   zum   Härten von eiweisshaltigen   Kmtsthornmassell.   
 EMI1.1 
 bei der Weiterbehandlung, sei es durch Pressen, Kneten oder Walzen oder auch erst beim Trocknen   a ! s Härtungsmittel   in einem Zeitpunkt wirken, in dem der Homogenisierungsvorgang schon zu Ende ist und daher nicht mehr gestört werden kann. 



   Besonders eignen sich für diesen Zweck das Oxymethylformamid und das   Oxymethylazetamid,   da diese Körper bei steigender Temperatur auch in erhöhtem Masse Formaldehyd abspalten, welche Eigenschaft von besonderem Werte ist. Die Oxymethylamide haben ausserdem noch den grossen Vorteil, dass sie im ersten Stadium plastizierend wirken und daher auch in Verbindung mit rascher wirkenden Härtungsmitteln verwendet werden können, deren zu rasches Angreifen durch ihre   anfängliche Plasti-   zierungswirkung verhindert wird. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Process for hardening Kmtsthorn massels containing protein.
 EMI1.1
 during further treatment, be it by pressing, kneading or rolling or even only during drying a! The hardening agents act at a point in time when the homogenization process has already ended and can therefore no longer be disturbed.



   Oxymethylformamide and oxymethylazetamide are particularly suitable for this purpose, as these bodies also split off formaldehyde to an increased extent with increasing temperature, which property is of particular value. The oxymethylamides also have the great advantage that they have a plasticizing effect in the first stage and can therefore also be used in conjunction with more rapidly acting hardening agents, whose too rapid attack is prevented by their initial plasticizing effect.
