Description

Verfahren zur gleichzeitigen Abtötung von Bakterien und Ungeziefer. Es ist bis jetzt kein Verfahren bekannt geworden, welches die gleichzeitige Abtötung von Bakterien und Ungeziefer in einem Arbeitsgang, d. h. durch einmalige Behandlung des in Betracht kommenden Raumes, ermöglicht, man mußte vielmehr bisher zur Erreichung des erstrebten Zweckes stets die in Betracht kommenden Mittel nacheinander anwenden, also mindestens zwei Beschickungen des betreffenden Raumes vornehmen.Process for the simultaneous killing of bacteria and vermin. Up to now, no method has become known which enables the simultaneous killing of bacteria and vermin in one operation, i. E. H. by one-time treatment of the room in question, instead one always had to use the means in question one after the other in order to achieve the intended purpose, i.e. at least two loads of the room in question.

Es wurde nun gefunden, daß man Bakterien und Ungeziefer mit ausgezeichnetem Erfolg in einer einzigen Operation abtöten und hierdurch erhebliche Vorteile in bezug auf Arbeits- und Zeitersparnis erzielen kann. wenn man Formaldehyd und Cyanwasserstoff oder dessen Derivate, z. B. Azetonitril oder Mischungen der in Betracht kommenden Cyanverbindungen, bei gewöhnlichem oder vermindertem Druck gleichzeitig anwendet.It has now been found that bacteria and vermin with excellent Killing success in a single operation and thereby providing significant benefits in can achieve in terms of labor and time savings. if you have formaldehyde and hydrogen cyanide or its derivatives, e.g. B. acetonitrile or mixtures of the suitable Cyan compounds, under ordinary or reduced pressure, simultaneously apply.

In Ausübung des Verfahrens werden die bei der Blausäureräucherei bzw. der Formaldehydvergasung üblichen Methoden angewendet mit der Maßgabe, daß der von Bakterien und Ungeziefer zu befreiende Raum mit beiden Gasen gleichzeitig behandelt wird.In the exercise of the procedure, the cyanide smokehouse resp. the formaldehyde gasification conventional methods used with the proviso that the of Bacteria and vermin free space treated with both gases at the same time will.

Durch die vereinigte gleichzeitige Anwendung von Formaldehyd und Blausäure wird der Vorteil erreicht, daß ein schnellerer Erfolg als durch getrennte Anwendung beider Agentien erzielt wird, und daß der Erfolg auch in solchen Fällen eintritt, in welchen die getrennte Zufuhr der Agentien ganz oder teilweise versagt. Die Ursache für das Eintreten 'der überraschenden Wirkung kann mit Sicherheit nicht angegeben werden. Möglicherweise ist der Erfolg darauf zurückzuführen, daß der an sich schon baktericid wirkende Formalde-hyd eine beträchtliche Reizwirkung auf die in Betracht kommenden Organismen ausübt, wodurch diese zu gesteigerter Atemtätigkeit und damit zur schnelleren Aufnahme der Blausäure veranlaßt werden.The combined simultaneous use of formaldehyde and hydrocyanic acid has the advantage that success is achieved more quickly than by using both agents separately, and that success also occurs in cases in which the separate supply of the agents fails completely or partially. The cause for the occurrence of the surprising effect cannot be given with certainty. The success is possibly due to the fact that the formaldehyde, which is already bactericidal, has a considerable irritating effect on the organisms in question, causing them to breathe more quickly and thus to more quickly absorb hydrogen cyanide.
