  Verfahren zur Herstellung eines zum Nachweis von Lost dienenden Reagenzmittels. 



   Die Erfindung betrifft ein Verfahren zur Herstellung eines zum Nachweis von Lost dienenden Reagenzmittels und besteht im wesentlichen darin, dass man Jod, Stärke und Jodmonochlorid mischt. 



  Man kann das Verfahren vorteilhaft so ausführen,   dass man zu einer Jodstärkelösung so   viel einer wässerigen   Jodehloridlösung   hinzufügt, dass die Blaufärbung der Stärke gerade verschwindet oder in eine Braunfärbung übergeht. Dass die Jodstärkereaktion durch Chlorjod verhindert wird, ist bereits bekannt. 



   Man kann dem Gemisch auch noch ein Jodat, z. B. Kaliumjodat, zusetzen, um die Reaktion noch empfindlicher zu machen. Bringt man ein derartiges Reagenzmittel mit Lost oder mit auf Lost zu untersuchenden Stoffen zusammen, so wird das Lost durch das Jodmonochlorid oxydiert, wobei sieh Salzsäure und Jodwasserstoffsäure bilden. Da nunmehr also das   Jodmonochlorid   aus der Lösung verschwunden ist, tritt die Blaufärbung der Jodstärke wieder auf. Das gegebenenfalls zuzusetzende Jodat gibt mit dem bei der Umsetzung von Lost in Jodmonochlorid entstehenden Jodwasserstoff freies Jod, welches die Blaufärbung der Stärke unterstÜtzt. 



   PATENT-ANSPRÜCHE :
1. Verfahren zur Herstellung eines zum Nachweis von Lost dienenden Reagenzmittels, dadurch gekennzeichnet, dass man Jod, Stärke und Jodmonochlorid mischt.

  Process for the production of a reagent used to detect mustard.



   The invention relates to a method for producing a reagent used to detect mustard and essentially consists in mixing iodine, starch and iodine monochloride.



  The method can advantageously be carried out in such a way that enough of an aqueous iodine chloride solution is added to an iodine starch solution that the blue color of the starch just disappears or turns into a brown color. It is already known that the iodine starch reaction is prevented by chlorine iodine.



   You can add an iodate to the mixture, e.g. B. potassium iodate, add to make the reaction even more sensitive. If such a reagent is brought together with mustard or with substances to be examined for mustard, the mustard is oxidized by the iodine monochloride, whereby hydrochloric acid and hydroiodic acid are formed. Since the iodine monochloride has now disappeared from the solution, the blue color of the iodine starch reappears. The iodate, which may be added, and the hydrogen iodide formed during the conversion of mustard into iodine monochloride, give free iodine, which supports the blue coloration of the starch.



   PATENT CLAIMS:
1. A method for producing a reagent used to detect mustard, characterized in that iodine, starch and iodine monochloride are mixed.
