KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Das Verfahren geht von der Beobachtung aus, daß die Peroxyde der' Erdalkalien mit den konzentrierten Lösungen der Arsensäure und Phosphorsäure sich schnell in der Weise umsetzen, daß die Erdalkalien in Lösung gehen und eine konzentrierte Lösung von H2O2 entsteht, die eine wesentliche Zersetzung nicht erleidet. Man nimmt z. B. 3 1 Wasser, trägt abwephselnd mit etwa 50 prozentiger Phosphorsäure 600 g Ba O2 ein und bringt durch Rühren letzteres in Lösung; nach Fällung des Erdalkalis mit Schwefelsäure kann man das H2 O2 abdestillieren.The method is based on the observation that the peroxides of the 'alkaline earths react quickly with the concentrated solutions of arsenic acid and phosphoric acid in such a way that the alkaline earths go into solution and a concentrated solution of H 2 O 2 is formed, which causes substantial decomposition does not suffer. One takes z. B. 3 1 water, wephselnd wephselnd with about 50 percent phosphoric acid in 600 g Ba O 2 and brings the latter into solution by stirring; after the alkaline earth has been precipitated with sulfuric acid, the H 2 O 2 can be distilled off.
In der französischen Patentschrift 458158 ist zwar ein Verfahren beschrieben, bei dem zur Herstellung von Wasserstoffsuperoxyd ebenfalls Phosphorsäure zur Anwendung kommt, die aus ihrer wässerigen Lösung mit Ba O2 gefällt wird. Versuche haben aber gezeigt, daßIn the French patent specification 458158 a process is described in which phosphoric acid is also used for the production of hydrogen peroxide, which is precipitated from its aqueous solution with BaO 2. But experiments have shown that
20. das Ba O2 dabei nur sehr unvollkommen aus-, genutzt wird. Das Reaktionsprodukt stellt eine dicke Masse dar, in deren Filtrat die Phosphorsäure nicht vollständig ausgefällt ist.20. The Ba O 2 is only used very imperfectly. The reaction product is a thick mass, in the filtrate of which the phosphoric acid has not completely precipitated.
