Description
Wasch-, Bleich- und Desinfektionsmittel Der Verwendung von unterchloriger Säure oder deren Salzen als Wasch-, Bleich- und Desinfektionsmittel steht bekanntlich die geringe Haltbarkeit der freier< Säure und der Hypochlorite im Wege. Beim Chlorkalk, der wegen seiner relativen Billigkeit heute noch verschiedentlich zu genannten Zwecken verwendet wird, wird außerdem dessen Gehalt an freiem Chlor und die Verunreinigung des mit ihm behandelten Gutes durch Calaiumhydroxyd als besonders nachteilig empfunden.Detergents, bleaches and disinfectants The use of hypochlorous Acid or its salts are known to be available as detergents, bleaches and disinfectants the short shelf life of the free <acid and the hypochlorite in the way. At the Chlorinated lime, which because of its relative cheapness today still variously to is used, its content of free chlorine and the contamination of the goods treated with it by calium hydroxide as special felt disadvantageous.
Ein Wasch-, Bleich- und Desinfektionsmittel, das von diesen Nachteilen völlig frei ist, ist in Adsorptionsmitteln, wie Gelen der I#,-ieselsäure oder der Oxyde von anderen Metalloiden oder von Metallen, wie des Aluminiums, des Eisens, des Titans- oder auch in aktiver Kohle, aufgespeichertes Chlor oder Chlorhydrat, das an Ort und Stelle der Verwendung mit alkalisch reagierenden Lösungen umgesetzt wird. Es hat sich nämlich überraschenderweise gezeigt, daß das in Adsorptionsmitteln beliebig lang und praktisch verlustlos aufzubewahrende Chlor durch alkalische Flüssigkeiten schon bei gewöhnlicher Temperatur augenblicklich dem Adsorptionsmittel entzogen und gebunden wird. Von dem sich glatt absetzenden, vom Chlor befreiten Gel kann, sofern seine Anwesenheit in besonderen Fällen nicht erwünscht sein sollte, abgegossen werden.A detergent, bleach and disinfectant that suffers from these disadvantages is completely free, is in adsorbents such as gels of silicic acid or Oxides of other metalloids or of metals such as aluminum, iron, of titanium or active carbon, stored chlorine or chlorohydrate, implemented on the spot of use with alkaline solutions will. It has been shown, surprisingly, that this is in adsorbents Chlorine can be stored for any length of time and with practically no loss thanks to alkaline liquids instantly withdrawn from the adsorbent at ordinary temperature and is bound. From the gel that settles smoothly and has been freed from chlorine, if his presence is not desired in special cases, poured off will.
Mit der Anwendung dieses Adsorptionsmittels .ist der weitere wesentliche Vorteil verbunden, daß man durch Zugabe von Lösungen z. B. kohlensaurer Salze, wie Alkalicarbonat oder -bicarbonat, statt der Hypochlorite die noch bedeutend besser bleichende unterchlorige Säure selbst in Lösung erhalten kann.With the use of this adsorbent .is the other essential The advantage associated that by adding solutions such. B. carbonate salts, such as Alkali carbonate or bicarbonate, instead of the hypochlorites, which are even better bleaching hypochlorous acid can be obtained even in solution.
