Description

Verfahren zur Herstellung von Lösungen stark keitutötender Wirkung Es ist bekannt, daß Alkalien und Säuren im allgemeinen entsprechend ihrem elektrischen Dissoziationsgrade, d. h. der Konzentration der in der Lösung enthaltenen OH-bzw. H-Ionen, desinfizierend wirken. Abgesehen von der Größe der titrimetrisch bestimmbaren Reaktionsänderung kommt dabei jeweils der spezifische Charakter des betreffenden Kations zum Ausdruck, wenn auch unter Umständen, besonders bei Säuren, Wirkungen zutage treten, welche weit über die nach dem Dissoziationsgrade zu erwartenden hinausgehen.Process for the preparation of solutions with a strong keitkutkidende effect It is known that alkalis and acids generally correspond to their electrical Degrees of dissociation, d. H. the concentration of the OH or contained in the solution. H ions, have a disinfecting effect. Apart from the size of the titrimetrically determinable The change in reaction depends on the specific character of the respective one Cations express, even if under certain circumstances, especially in the case of acids, effects come to light which go far beyond what is to be expected according to the degree of dissociation.

In den neutralen Halogensalzen der Alkali-und Erdalkalimetalle kommt der spezifische Charakter des betreffenden Metalles in analoger Weise zum Ausdruck wie bei den Alkalien. Doch spielen sie in der praktischen Desinfektion keine Rolle, indem z. B. Chlornatrium erst in 8prozentiger Lösung die Entwicklung von Milzbrandbazillen hemmt, während Eiterkokken, Typhus-, Schweinerotlauf-und Tuberkelbazillen sowie Milzbrandsporen noch nach Wochen und Monaten resistent bleiben. Vollständige Ent-,vickelungshemmung tritt erst bei Konzentration über 25 01" Chlornatrium ein.In the neutral halogen salts the alkali and alkaline earth metals come the specific character of the metal in question in an analogous way to expression as with the alkalis. But they do not play a role in practical disinfection, by z. B. sodium chloride only in 8 percent solution the development of anthrax bacilli inhibits while pus cocci, typhoid, swine rot and tubercle bacilli as well Anthrax spores remain resistant even after weeks and months. Complete anti-wrapping inhibition occurs only at a concentration of more than 25 01 "sodium chloride.

Es wurde nun gefunden, daß mit außerordentlich schwachen, wässerigen Lösungen von Alkalihydraten oder Säuren oder mehrhasigen Salzen, welche kaum oder nur mäßig keimtötend wirken, bei Zusatz von Neutralsalzen in Konzentrationen, welche an sich praktisch keinerlei desinfizierende Wirkungen ausüben, erhebliche desinfektorische Effekte erzielt bzw. eine Steigerung derselben um ein Vielfaches herbeigeführt werden können.It has now been found that with extremely weak, watery Solutions of alkali hydrates or acids or multiphase salts, which hardly or only have a moderate germicidal effect when neutral salts are added in concentrations which have practically no disinfecting effects per se, considerable disinfectant Effects can be achieved or an increase in the same can be brought about many times over can.

Macht man z. B. eine n/300 Natriumphosphatlösung, welche an sich kaum keimhemmende Wirkung entfaltet, blutisotonisch mit Natriumchlorid; welches in dieser Konzentration keine Desinfektionswirkung besitzt, so entsteht eine stark keimtötende Flüssigkeit, welche, gleichwohl, subkutan oder intravenös oder interperitoneal Tieren einverleibt, keine zellschädigende Wirkung ausübt, selbst wenn bis zu einem Viertel, ja bis zur Hälfte der Ges.amtblutmenge von solcher Flüssigkeit einverleibt wird.Do you z. B. a n / 300 sodium phosphate solution, which in itself hardly germ-inhibiting effect unfolds, blood isotonic with sodium chloride; which in this Concentration has no disinfecting effect, so it is strongly germicidal Fluid, which, however, subcutaneously or intravenously or interperitoneally animals incorporated, has no cell-damaging effect, even if up to a quarter, yes, up to half of the total amount of blood is absorbed by such fluid.

Das Verfahren zur Herstellung von indifferenten Salzlösungen stark keimtötender Wirkung besteht erfindungsgemäß darin, daß man zu Lösungen von beispielsweise HCI, NaOH, Na,C03, Na3P0" deren Konzentration kleiner als %" n ist, 0,859o NaCI zugibt.The process for the preparation of salt solutions indifferent strong germicidal action according to the invention consists in the fact that one is added to solutions of, for example, HCI, NaOH, Na, C03, Na3P0 "whose concentration is less than%" n, 0,859o NaCl added.

Ausführungsbeispiel r 1 0,005 n NaOH wird mit 8,5 g NaCl versetzt. Werden 9,9 ccm dieser Lösung mit o,i ccm einer 24stündigen Bouillonkultur von bacterium coli beimpft und sofort, nach 24 Stunden und nach io Tagen Proben auf optimale Nährböden. übertragen, so zeigt sich, daß bereits bei sofortiger Aussaat aus der keimtötenden Lösung weniger als die Hälfte der eingebrachten Keime sich entwickeln, nach 24 Stunden dagegen völlige Abtötung stattgefunden hat.Embodiment r 1 0.005 N NaOH is mixed with 8.5 g NaCl. Will 9.9 cc of this solution with 0.1 cc of a 24-hour broth culture of bacterium coli and immediately after 24 hours and 10 days samples on optimal culture media. transferred, it shows that even with immediate sowing from the germicidal Solution less than half of the germs introduced develop after 24 hours on the other hand, complete destruction has taken place.

Nimmt man nur physiologische Kochsalzlösung oder 0,005 NaOH, so erfolgt praktisch keine Abtötung.If only physiological saline solution or 0.005 NaOH is used, there is practically no killing.
