Verfahren zur Geruch- und Geschmacklosmachung des technischen Hexachlorcyclohexan.Process for eliminating smell and taste of technical hexachlorocyclohexane.
Es ist bereits vorgeschlagen worden Hexachlorcyclohexan durch Behandlung mit konzentrierter Salpetersäure von dem ihm anhaftenden unangenehmen Geruch und Geschmack zu befreien. Es geht aus diesem Vorschlag nicht hervor, ob es sich dabei um eine Nitrierung oder Oxydation handeIt.It has already been suggested by treatment with concentrated nitric acid of hexachlorocyclohexane to free the unpleasant smell and taste attached to it. It does not appear from this proposal whether it is a matter of nitration or oxidation.
Gemäß der vorliegenden Neuerung wurde nun gefunden, daß allgemein Oxydationsmittel geeignet sind, den gewünschten Effekt zu erzielen, beispielsweise können genannt werden: Chromsäure,Ealiumpermanganat, Kaliumpersulfat. Grundsätzlich kann in der Kälte oder in der Wärme gearbeitet werden. Vorteilhafterweise wird jedoch mit der wässerigen Lösung des Oxydationsmittels gearbeitet, während das Hexachlorcyclohexan in einem mit Wasser mischbaren organischen Lösungsmittel gelöst ist.According to the present innovation it has now been found that generally oxidizing agents are suitable to achieve the desired effect, for example can the following are mentioned: chromic acid, ealium permanganate, potassium persulphate. Basically, you can work in the cold or in the warm. Advantageously, will but worked with the aqueous solution of the oxidizing agent, while the hexachlorocyclohexane in one is dissolved with water-miscible organic solvent.
3 g Kaliumpersulfat, in 6 ecm Wasser kalt gelöst, werden zu 10 g Hexachlorcyclohexan in 400 ecm LetLanol auf einmal zugefügt. Man läßt über Wacht stellen und scheidet das Hexachlorcyclohexan durch Wasserzugabe aas. Der lästige Geruch und Geschmack ist nunmehr völlig geschwunden.3 g of potassium persulfate, dissolved in 6 ecm of cold water, are to be used to 10 g hexachlorocyclohexane in 400 ecm LetLanol at once added. One lets watch over and separates that Hexachlorocyclohexane by adding water aas. The annoying smell and taste has now completely disappeared.
