Description
Verfahren zur Herstellung von sich nicht zersetzenden, Notalle nicht angreifenden Desinfektions- und Reinigungsmitteln. I <B>R</B> fige 1,-Pimi#ötünd-e Die ausserordentlich gü <B>9</B> Wirkung das Natriumhypochlorits, ist be- kannt- <B>Aus</B> diesem Grunde finden Lösungen von Ilypoelilorit vielfach zur Desinfektio-n und Reinigung Verwendung,
und zwa-r insl- t3 besondere von metallenen Gerätsehaften. WerkzeUgen und Gegenständen" -wie sie in Molkerei- und Brauereibetrieben und für die Krankenpflege, besonders in Krankenhäu sern, _Verwendung finden. Hypochloritlauge hat jedoch den Nachteil, dass sie Metalle stark angreift und sich in Gegenwart von Metallen, selbst fa.st explob:ieknsartig zersetzt.
Hierdurch tritt nicht nur oft eine Beschädi gung der Geräte auf, sondern die Lauge .selbst, wird infolgedessen unwirksam.
Um ihre Reinigungskraft zu erhöhen und da.s den behandelten Gefässen anhaftende Fett besser entfernen zu können" hat man der Hvpooliloritlösung Natroulauge zuge setzt. Die keimtötenden Eigenschaften einer solchen Mischung sind zwar vorzüglich. Trotzdem hat sich eine derartige Lösuno- ebenfalls nicht bewährt, weil Metalle" insbe sondere Zinn und Aluminium, durch das Chlor und,die überschüssige Natronlauge so stark angegriffen werden, dass die Lebens dauer der Geräte hierdurch sehr vermindert wird.
Es wurde bereits vorgeschlagen!, feste Lösung,-en -von Alkalihypochloriten zu gewin nen, indem man Wasserglasläsung,eindampft und verrührt, bis eine halberstarrte Lösung entstanden ist, zu der die Natriumhypo- chloritlösung gegeben wird oder eine Mi- "cliung von Natriumllypoc'hloritlösung, Was serglas und calcinierter Sada herzustellen.
Da,9 in diesen festen Lösungen enthaltene Wass,erglasi lässtsiell nicht wieder in Lösung bringen, weshalb sieh das Präparat als Desinfektions- und Reinigungsmittel nicht eignet.
Wie, nun gefunden wurde, bleiben die günstigen Eigenschaften der Hypochlorit- lösung vollen Umfanges, erhalten, während die geschilderten Nachteile so. gut wie ganz verschwinden, wenn man sie mit einern Zu satz von Wasserglas versieht.
Längere Zeit hindurch angestellte Beobachtungen haben erg,eben, dass eine derartige Wasserglas ent haltende Hypoeliloritlösung Metalle fast gar nicht angreift, und dass Jie mit Chlorlauge ohne diesen Zusatz beobachteten Zersetzun- gen niehteintreten. Die Wirkung ist wahr scheinlich darauf zurückzuführen,
dass das Wasserglae innerhalb des Flüssigkeitsgemi- selies als kolloidale SchutzschieUt für die Metalle, wirkt und infolgedessen chemische Umsetzungen zwischen Metall und Chlor lauge verhindert-.
Das auf diese Weise hergestellte Desin- fektions- und Reinigungsmittel kann nicht nur mit Vorteil zum Behandeln von Gerät schaften und dergleichen für Molkerei- Brauerei- und Fleischereibetriebe, sowie für ,die Krankenpflege Verwendung finden, son- dQrn eignet sich auch besonders zum Reini gen von Flaschen, in welche Bier, wein, Mineralwasser und andere Getränke abge füllt werden, um die Metallteileder für die Reinigung benutzten Geräte und 3/lasc#hi- neu zu schonen.
Gemäss der Erfindung erfolgt der Zusatz von Wasserglas, das in Form von Kalium- oder Natronwasserglas Verwendung finden kann, zweckmässig in solchen Mengen, dass keine Ausfällung stattfindet.
Das Desinfektionsmittel wird zum Bei spiel in folgender WeiseUergestellt.
Man bereitet eine Mischung aus:<B>562</B> gr- Natriumhypochloritlösung vom spez. Gewicht 1,125 und<B>250</B> gr Natronlauge vom spez. Gewieht <B>1,383. 500</B> gr dieser Lösung werden mit<B>300</B> gr Natronwassergolast 38/40' B6 ver setzt.
Für die Zwecke der Desinfektion findet ,die konzentrierte Lösung in entsprechender Verdünnung Anwendung. Zur Erreieliung des gewünschten Zweckes genügen Lösungen. welche 1/4 bisi 2<B>%</B> der konzentrierten Flüssig- el keit enthalten.
Die schützende Wirkung von Wasser glas gegenüber Metallen kann bei der Iler- stellung von Desinfektionsmitteln benutzt werden, welche aus Lösungen von Alkali- oder Erdalkaliliypochloriten, allein oder aus Lösungen von Hypochloriten und ätzenden Alkalien bestehen.
Process for the production of non-decomposing, emergency non-corrosive disinfectants and cleaning agents. I <B> R </B> fig 1, -Pimi # ötünd-e The extraordinarily beneficial effect of sodium hypochlorite is known- <B> For this reason, solutions are found Ilypoelilorit is widely used for disinfection and cleaning,
and zwa-r insl-t3 special of metal device sheaths. Tools and objects "- as they are used in dairy and breweries and for nursing, especially in hospitals. Hypochlorite liquor has the disadvantage, however, that it attacks metals strongly and, in the presence of metals, even becomes explob: like a knot decomposed.
This not only often results in damage to the devices, but the lye itself becomes ineffective as a result.
In order to increase its cleaning power and to be able to better remove the fat adhering to the treated vessels, "sodium hydroxide solution has been added to the poolilorite solution. The germicidal properties of such a mixture are excellent. Nevertheless, such a solution has also not proven itself, because metals "In particular, tin and aluminum, the chlorine and the excess caustic soda are so strongly attacked that the service life of the devices is greatly reduced.
It has already been proposed to obtain solid solutions of alkali hypochlorites by evaporating and stirring water glass solution until a semi-solid solution has formed, to which the sodium hypochlorite solution is added or a mixture of sodium hypochlorite to produce chlorite solution, water glass and calcined sada.
Since the water contained in these solid solutions cannot be brought back into solution, the preparation is therefore unsuitable as a disinfectant and cleaning agent.
As has now been found, the favorable properties of the hypochlorite solution are retained in full, while the disadvantages described are so. almost completely disappear if you add a glass of water to them.
Observations made over a long period of time have shown that a hypoelilorite solution containing this type of water glass hardly attacks metals at all, and that the decomposition observed with sodium chloride solution without this addition does not occur. The effect is likely due to
that the water glass within the liquid mixture acts as a colloidal protective layer for the metals and consequently prevents chemical reactions between metal and chlorine lye.
The disinfectant and cleaning agent produced in this way can not only be used advantageously for treating equipment and the like for dairy, breweries and butchers, as well as for nursing, but is also particularly suitable for cleaning Bottles in which beer, wine, mineral water and other beverages are filled in order to protect the metal parts of the devices used for cleaning and 3 / lasc # hi-neu.
According to the invention, water glass, which can be used in the form of potassium or soda water glass, is expediently added in such amounts that no precipitation takes place.
The disinfectant is produced in the following way, for example.
A mixture is prepared from: <B> 562 </B> gr sodium hypochlorite solution of spec. Weight 1.125 and <B> 250 </B> gr sodium hydroxide solution from spec. Weight <B> 1,383. 500 grams of this solution are mixed with 300 grams of 38/40 'B6 soda water.
For the purpose of disinfection, the concentrated solution is used in appropriate dilution. Solutions are sufficient to achieve the desired purpose. which contain 1/4 to 2 <B>% </B> of the concentrated liquid.
The protective effect of water glass against metals can be used in the preparation of disinfectants, which consist of solutions of alkali or alkaline earth metal hypochlorites, alone or from solutions of hypochlorites and caustic alkalis.
