wasserunlöslich zu machen.to make water insoluble.
Zusatz zum Patente 207636 vom 20. November 1907.Addendum to patent 207636 from November 20, 1907.
Patentiert im Deutschen Reiche vom 19. Juni 1908 ab. Längste Dauer: 19. November 1922. Patented in the German Empire on June 19, 1908. Longest duration: November 19, 1922.
Durch Patent 207636 ist ein Verfahren geschützt, die Wurzelsubstanz von Amorphophallusarten
oder die in ihr enthaltenen Schleimstoffe wasserunlöslich zu machen.
Das Verfahren besteht in der Anwendung von Hitze eventuell nach vorausgegangener
Behandlung der genannten Stoffe mit Ätzalkalien. Patent 207636 protects a process to make the root substance of Amorphophallus species or the mucous substances contained in them insoluble in water.
The process consists in the application of heat, possibly after the aforementioned substances have been treated with caustic alkalis.
Die weitere Bearbeitung dieses Verfahrens zeigte, daß man die Hitze entbehren und durch Einwirkung von Ätzalkalien auf die trockene Wurzelsubstanz ein Produkt gewinnen kann, dessen Lösung oder Quellung in getrocknetem Zustande wasserunlöslich geworden ist.The further processing of this process showed that one can dispense with the heat and obtain a product through the action of caustic alkalis on the dry root substance can, its solution or swelling in the dried state become insoluble in water is.
Trägt man z, B., wie in der Beschreibung des Hauptpatentes ausgeführt wird, die Wurzelsubstanz in Ätzalkalilösung (Natronlauge) ein, so erstarrt bei häufigem Umrühren die anfangs flüssige Masse bald. Nach längerem Stehen bei gewöhnlicher Temperatur bildet sich eine Masse, welche nach entsprechendem Zusatz von Wasser auf Unterlagen gegossen nach dem Eintrocknen wasserunlösliche Häute bildet und z. B. zum Imprägnieren bzw. Anstreichen von Geweben geeignet ist, um letztere wasserundurchlässlig und gasdicht zu machen.For example, as stated in the description of the main patent, the root substance is carried in a caustic alkali solution (caustic soda), then the initially solidifies with frequent stirring liquid mass soon. After standing for a long time at ordinary temperature, a mass forms, which according to the same Addition of water on substrates poured water-insoluble skins after drying forms and z. B. is suitable for impregnating or painting fabrics to the latter to make water impermeable and gas tight.
