Description

Nachweismittel für flüssige oder dampfförmige Kampfstoffe Zusatz zum Patent 722 29I Gegenstand des Hauptpatents bildet ein Nachweismittel für flüssige oder dampfförmige Kampfstoffe, bestehend aus einem Gemisch eines in den Kampfstoffen löslichen Farbstoffes mit einer pulverförmigen mineralischen Trägermasse, welche die Farbstoffauflösung durch Verfärbung anzeigt. Die bisher verwendeten Nachweismittel dieser Art, bei denen beispielsweise die Trägermasse aus Talkum besteht, haben den Nachteil, daß sich die Trägermasse schon während der Lagerung verfärbt, so daß durch die beim praktischen Gebrauch stattfindende Auflösung des Farbstoffes in den Kampfstoffen eine genügend auffällige Anderung des Farbtones der Trägermasse nicht mehr eintreten kann. Es ist jedoch von größter Bedeutung, daß die Nachweismittel lagerbeständig sind, da sie in großen Mengen für unabsehbare Zeit vorrätig gehalten werden müssen, um im Kriegsfalle verfügbar zu sein.Detection agent for liquid or vaporous warfare agents Patent 722 29I The subject of the main patent is a detection means for liquids or vaporous warfare agents, consisting of a mixture of one of the warfare agents soluble dye with a powdery mineral carrier, which indicates dye dissolution by discoloration. The means of detection used so far of this type, in which, for example, the carrier mass consists of talc, have the Disadvantage that the carrier mass discolored during storage, so that through the dissolution of the dye in the warfare agents during practical use a sufficiently noticeable change in the shade of the carrier material no longer occurs can. However, it is of the utmost importance that the detection means are shelf-stable because they have to be kept in stock in large quantities for an indefinite period of time, to be available in case of war.

Es wurde gefunden, daß die Forderung nach unbegrenzter Lagerbeständigkeit des Nachweismittels durch die Verwendung von Quarzmehl als Trägermasse für den Farbstoff erfüllt wird. Besonders bewährt hat sich Quarzmehl im Gemisch mit Sudanrot. Es können natürlich auch andere Farbstoffe, z. B. Rosanilin oder Cerasinviolett, verwendet werden. Das Quarzmehl hat gegenüber dem bisher vorzugsweise als Trägermasse verwendeten Talkum den weiteren Vorteil, daß es die Neigung des letzteren zum Verkleben nicht aufweist. Es besitzt infolgedessen eine bessere Streufähigkeit und läßt sich gleichmäßiger mit dem Farbstoff vermischen. It has been found that the requirement for unlimited shelf life the detection means through the use of quartz powder as a carrier for the dye is fulfilled. Quartz flour mixed with Sudan red has proven to be particularly effective. It can of course other dyes, e.g. B. rosaniline or cerasin violet used will. The quartz powder has, compared to that which has hitherto been used preferably as a carrier Talc has the further advantage that it does not have the tendency of the latter to stick together having. As a result, it has better throwing power and is more uniform mix with the dye.

Daraus ergibt sich eine höhere Zuverlässigkeit und Empfindlichkeit des Nachweismittels, insbesondere bei Verwendung an schwer zugänglichen Stellen und beim Vorhandensein nur geringer Kampfstoffmengen.This results in higher reliability and sensitivity of the means of detection, especially when used in hard-to-reach places and in the presence of only small amounts of warfare agents.

Die Verwendung von Quarzmehl als Trägermasse für fein zu verteilende Stoffe ist an sich schon bekannt. Man hat nämlich schon vorgeschlagen, Benzoylsuperoxyd während der Darstellung auf Quarzmehl niederzuschlagen, um eine feine Verteilung und damit eine verbesserte Reaktionsfähigkeit des niedergeschlagenen Produktes bei seiner Weiterverwendung zu gewährleisten. Aus dieser Nutzanwendung des Quarzmehles konnte jedoch eine Eignung für den vorliegenden Zweck, bei dem es sich insbesondere um die Erhöhung der Lagerbeständigkeit des Nachweismittels handelt, nicht erkannt werden. The use of quartz powder as a carrier for finely distributed Substances are already known per se. It has already been suggested that benzoyl peroxide be used Precipitate on quartz powder during the display to ensure a fine distribution and thus an improved reactivity of the precipitated product to ensure its further use. From this useful application of quartz flour could, however, be suitable for the present purpose, which is in particular the increase in the storage stability of the detection agent is not recognized will.
