Zusatz zum Patent 232001 vom 19. April 1910.Addendum to patent 232001 from April 19, 1910.
Patentiert im Deutschen Reiche vom 7. Dezember 1910 ab. Längste Dauer: 18. April 1925.Patented in the German Empire on December 7, 1910. Longest duration: April 18, 1925.
Es ist gelungen, in ähnlicher Weise, wie es gemäß Patentschrift 232001 für die Herstellung von Erdalkalisuperoxyden vorgeschlagen worden, Perborate herzustellen. Es hat sich nämlich gezeigt, daß ζ. B. eine Lösung von Borax in geschmolzenem Ätznatron imstande ist, Sauerstoff aufzunehmen, wenn man diesen bei erhöhtem Druck hindurchleitet. Es ist hierbei wichtig, eine möglichst niedere Temperatur der lösenden Schmelze zu wählen, da bei hoher Temperatur die Perborate zersetzt werden.It has succeeded in a similar way as it is according to patent specification 232001 for the production of alkaline earth peroxides have been proposed to produce perborates. It has namely shown that ζ. B. a solution of borax in molten caustic soda capable is to absorb oxygen when it is passed through at increased pressure. It is It is important here to choose the lowest possible temperature for the dissolving melt, since at high temperature the perborates are decomposed.
Zur Ausführung des Verfahrens löst man z. B. Borax oder Borsäure in dem niedrigstTo carry out the method you solve z. B. Borax or boric acid in the lowest
schmelzenden Gemisch von Ätznatron und Ätzkali, und leitet bei etwa 200 ° C. in einem druckfesten Eisengefäß komprimierten Sauerstoff von etwa 50 Atm. durch die Schmelze. Nach beendeter Oxydation läßt man die Schmelze unter Aufrechterhaltung des Druckes abkühlen und wäscht mit Alkohol aus. Die Ätzalkalien werden dadurch gelöst, und das Perborat bleibt als Niederschlag zurück. Während die früheren Verfahren meist Natriumsuperoxyd zur Herstellung von Perboraten benutzten, kann man nach dem vorliegenden Verfahren den leicht zugänglichen komprimierten Sauerstoff direkt. an die Borverbindung anlagern, und man erspart die umständliche und kostspielige Herstellung des Natriumsuperoxyds. Als Katalysator werden zweckmäßig Eisen - Mangan -Vanadinverbindungen benutzt.melting mixture of caustic soda and caustic potash, and conducts at about 200 ° C. in one Pressure-tight iron vessel compressed oxygen of about 50 atm. through the melt. When the oxidation has ended, the melt is left while the pressure is maintained cool and wash off with alcohol. The caustic alkalis are thereby dissolved, and that Perborate remains as a precipitate. While the earlier procedures mostly sodium peroxide used for the production of perborates, you can use the present process the easily accessible compressed Oxygen directly. add to the boron compound, and you save the cumbersome and expensive manufacture of sodium peroxide. Suitable as a catalyst Iron-manganese-vanadium compounds used.
