KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei weiterer Ausarbeitung des Verfahrens, das dem Hauptpatent 220493 zugrunde liegt, wurde gefunden, daß auch freie Sulfosäuren das Gelatinieren der mit Formalin versetzten Protalbinlösungen o. dgl. eiweißhaltigen Flüssigkeiten verhindern, ohne die Wirkung des Formalins — Wasserunlöslichkeit der eingetrockneten Lösung — zu beeinträchtigen. Die Herstellung der Lösung geschieht nach dem Beispiele des Hauptpatents, wobei ß-Naphtol durch Naphthalinsulf osäure ersetzt werden kann.In further elaboration of the process on which the main patent 220493 is based, it was found that free sulfonic acids also gelatinized the with formalin Prevent protalbin solutions or the like. Protein-containing liquids without the effect of the Formalin - water insolubility of the dried solution - to impair. the The solution is produced according to the examples of the main patent, with ß-naphtol can be replaced by naphthalenesulfonic acid.
