Description

Apparate zur Aufbewahrung und Verwendung von ätzalkalischen Wasserstoffsuperoxydlösungen Das Bleichen mit Wasserstoffsuperoxydbädern wird in der Regel in Holzgefäßen durchgeführt, wobei sich der Nachteil zeigt, daß das Holz, namentlich von warmen Bädern, stark angegriffen wird.Apparatus for the storage and use of caustic hydrogen peroxide solutions Bleaching with hydrogen peroxide baths is usually carried out in wooden vessels, The disadvantage is that the wood, especially from warm baths, is strong is attacked.

Zum Heizen solcher Bäder wurden Rohre aus Blei oder Eisen verwendet, die jedoch nicht ohne katalytischen Einfluß sind, die Bäder also zersetzen.Pipes made of lead or iron were used to heat such baths, which, however, are not without a catalytic influence and therefore decompose the baths.

Von anderer Seite wurde die Verwendung von Nickelrohren vorgeschlagen, die zum Teil gute Erfolge ergaben.The use of nickel tubes has been suggested by others, some of which resulted in good results.

In der Patentschrift 233 856 wird Aluminium zur Herstellung und Aufbewahrung vonWasserstoffsuperoxyd empfohlen. Dieses Metall ist zwar ohne katalytische Einwirkung auf Wasserstoffsuperoxyd auch hinsichtlich der Verwendbarkeit geeignet, widersteht aber nicht auch nur ganz schwach alkalischen Lösungen. Da die Herstellung nur immer in sauren Lösungen erfolgt, eignet sich Aluminium wohl für den angegebenen Zweck. Es mußte jedoch erwartet werden, daß die immer alkalischen Bleichlösungen Aluminium angreifen, das bereits in kalten ätzalkalischen Lösungen von 1/"" /, Gehalt schnell zerstört wird.In patent 233,856, aluminum is recommended for the manufacture and storage of hydrogen peroxide. Although this metal is also suitable in terms of usability without catalytic action on hydrogen peroxide, it does not withstand even very weakly alkaline solutions. Since the production always takes place in acidic solutions, aluminum is probably suitable for the stated purpose. It had to be expected, however, that the always alkaline bleaching solutions attack aluminum, which is quickly destroyed in cold, caustic alkaline solutions with a content of 1 / "" /.

Ganz überraschenderweise zeigt sich aber, daß Zusätze von Wasserstoffsuperoxyd eine schützende Wirkung auf das Aluminium ausüben, derart, daß die in der Praxis der Bleicherei vorkommenden Konzentrationen an Alkali bei Gegenwart von Wasserstoffsuperoxyd keinerlei Angriff auf Aluminium zeigen. Damit ist in diesem Metall ein hervorragend geeignetes Konstruktionsmaterial für Sauerstoffbleichanlagen gefunden.Quite surprisingly, however, it is found that additions of hydrogen peroxide exert a protective effect on the aluminum, such that in practice the concentrations of alkali occurring in the bleaching plant in the presence of hydrogen peroxide show no attack on aluminum. So that is an excellent in this metal found suitable construction material for oxygen bleaching plants.
