Description

Verfahren zur Verbesserung der Eigenschaften von Kunsthorn aus Casein u. dgl. Das aus Casein oder ähnlichen Stoffen nach den bekannten Verfahren erhaltene Kunsthorn ist in der Regel gelblichbraun und undurchsichtig. Es ist bekannt, daß alkylierte Amine, insbesondere Diarvlalkylamine, z. B. Methyldiphenylamin, eine aufhellende und klärende Wirkung auf derartige Kunsthornmassen ausüben.Process for improving the properties of artificial horn made from casein and the like that obtained from casein or the like by the known methods Artificial horn is usually yellowish brown and opaque. It is known that alkylated amines, especially diarvlalkylamines, e.g. B. methyldiphenylamine, a have a lightening and clarifying effect on such artificial horn materials.

Es wurde nun gefunden, daß neutrale Phosphorsäureester, insbesondereTriarylphosphate, in ganz hervorragendem Maße verbessernd auf die Eigenschaften des Kunsthorns aus Casein o. dgl. wirken. Die Massen werden aufgehellt und geklärt, auch wird eine Verbesserung der elastischen Eigenschaften des Kunsthorns bewirkt.It has now been found that neutral phosphoric acid esters, in particular triaryl phosphates, improves the properties of the artificial horn in an excellent way Casein or the like act. The masses are lightened and cleared, too, becomes one Improves the elastic properties of the artificial horn.

Besonders vorzügliche Resultate erhält man, wenn man die Phosphorsäureester einem durch Behandlung mit reduzierenden Mitteln gebleichten Casein, am besten gleichzeitig mit den reduzierenden Mitteln, zusetzt. Es wird dann ein nahezu farbloses und glasartiges Kunsthorn erhalten.Particularly excellent results are obtained when using the phosphoric acid ester a casein bleached by treatment with reducing agents, preferably at the same time with the reducing agents. It then becomes almost colorless and glass-like Artificial horn received.

Beispiel 17o Teile Casein werden mit einer Lösung von 3,q. Teilen wasserfreiem Natriumhydrosulfit in 7o Teilen Wasser vermahlen, während man eine Lösung von 3,4 Teilen Triphenylphosphat in 2o Teilen Alkohol dem Mahlgut zusetzt. Die erhaltene Masse, in üblicherWeiseplastifiziert, liefert ein nahezu farbloses und durchsichtiges Kunsthorn.Example 17o parts of casein are mixed with a solution of 3, q. share Grind anhydrous sodium hydrosulfite in 70 parts of water while making a A solution of 3.4 parts of triphenyl phosphate in 2o parts of alcohol is added to the millbase. The mass obtained, plasticized in the usual way, gives an almost colorless one and transparent synthetic horn.
