Description
Verfahren zur Verbesserung der Eigenschaften von Kunsthorn aus Casein o. dgl. Das nach den bisher bekannten Verfahren hergestellte Kunsthorn stellt eine mehr oder weniger getrübte, bräunlichgelbe Masse dar. Ein Mittel zum Bleichen gab es bisher nicht.Process for improving the properties of artificial horn made from casein o. The like. The artificial horn produced by the previously known method is a more or less cloudy, brownish-yellow mass. A means for bleaching gave it has not yet.
Es wurde gefunden, daB reduzierend wirkende Mittel, insbesondere Hydrosulfite, dem Casein o. dgl. während der Verarbeitung zugesetzt. eine vorzüglich bleichende Wirkung ausüben.It has been found that reducing agents, in particular hydrosulfites, added to the casein or the like during processing. an exquisitely bleaching one Have an effect.
Beispiel 3,4 Teile Natriumhydrosulfit, in 7o Teilen Wasser gelöst. werden 17o Teilen Casein zugesetzt. Die Masse in der üblichen Weise weiterverarbeitet. gibt ein nahezu farbloses Kunsthorn.Example 3.4 parts of sodium hydrosulfite dissolved in 70 parts of water. 170 parts of casein are added. The mass is processed in the usual way. gives an almost colorless artificial horn.
