Verfahren zur Herstellung haltbarer, fester, mit Wasser Wasserstofsuperoxyd entwickelnder Perborat-Mischungen aus Natriumperborat und einem festen sauren Salz.
Die Wirksamkeit des Natriumperborats in wässeriger Lösung als Desinfektionsmittel beruht auf seiner Dissoziierbarkeit in Wasserstoffsuperoxyd und borsaures Salz. Da das Natrmmperhorat schwer löslich und nur teilweise dissoziiert ist, so tritt die volle Wirkung desselben erst dann ein, wenn man durch Zusatz verdünnter Säuren aus dem Szle das Wasserstoffsuperoxyd freimacht. Man hat diese Dissoziation erreicht durch Zusatz von Phosphorsäure oder von sauren Salzen zu den wässerigen Lösungen von Natriumperborat. Dagegen war es
EMI1.1
mit sauren Agenzien herzustellen, da sich diese Mischungen in kurzer Zeit völlig zersetzten. Neuerdings hat Byk (Französisches Patent Nr. 401911 vom 9.
April 1909) diesen Übsst- stand dadurch zu vermeiden gesucht, dass er entwässertes Natriumperborat mit Natrium- bitartrat mischte. Doch zeigt auch diese Mischung insofern noch einen Nachteil, als das entwässerte Natriumperborat naturgemäss bestrebt ist, sich wiederum mit Wasser zu sättigen und so in die zersetzliche Mischung überzugehen : die Salzmischung ist nach Angabe hygroskopisch und muss daher vorsichtig aufbewahrt werden.
Nach allen vorliegenden Erfahrungen ist die beständigste Form des Natriumperborats
EMI1.2
Bisher ist es aber nicht gelungen, haltbare Mischungen gerade dieses Salzes mit sauret salzen hpr/ustpllcn. Es wurde nun gefunden, dass die gut kristallisierenden Natriumsalze der Sulfo-
EMI1.3
und sulfobenzoessures Natron zerfallen.
Beispiel : 10 kg kristallisiertes Natrillmperborat werden mit 14 6 k @g saurem sulfobenzoesaurem Natron zu einem feinen Pulver gemischt. 12 g dieser Mischung in 100 cm3 Wasser entsprechen einer einprozentigen Lösung von Wasserstoffsuperoxyd, die gleichzeitig l'8 o Borsäure enthält.

Process for the production of durable, solid perborate mixtures from sodium perborate and a solid acid salt which develop hydrogen peroxide with water.
The effectiveness of sodium perborate in aqueous solution as a disinfectant is based on its ability to dissociate into hydrogen peroxide and boric acid salt. Since the sodium perhorate is sparingly soluble and only partially dissociated, its full effect only occurs when the hydrogen peroxide is freed from the salt by adding dilute acids. This dissociation was achieved by adding phosphoric acid or acid salts to the aqueous solutions of sodium perborate. It was against it
EMI1.1
with acidic agents, as these mixtures completely decompose in a short time. Recently Byk (French patent no.
April 1909) sought to avoid this excess by mixing dehydrated sodium perborate with sodium bitartrate. However, this mixture also has a disadvantage insofar as the dehydrated sodium perborate naturally strives to become saturated again with water and thus to convert into the decomposing mixture: the salt mixture is said to be hygroscopic and must therefore be stored carefully.
According to all available experience, sodium perborate is the most stable form
EMI1.2
So far, however, it has not been possible to produce durable mixtures of this particular salt with acidic salts. It has now been found that the well crystallizing sodium salts of the sulfo-
EMI1.3
and sulfobenzoessures soda disintegrate.
Example: 10 kg of crystallized sodium perborate are mixed with 14 6 kg of acid sulfobenzoate to form a fine powder. 12 g of this mixture in 100 cm3 of water correspond to a one percent solution of hydrogen peroxide, which at the same time contains 1,8% boric acid.
