Description

Verfahren zur Reinigung voT. freies Halogen enthaltenden Halogenwasserstoffen Bei vielen Prozessen, beispielsweise bei der Halogenierung organischer Verbindungen, fallen häufig große Halogenwasserstoffmengen, insbesondere Chlorwasserstoff, an, die durch Halogen, insbesondere durch Chlor, verunreinigt sind. Diese Halogenwasserstoffmengen lassen sich aber wegen ihres Gehaltes an freiem Halogen nur schwer verwerten.Procedure for cleaning up voT. hydrogen halides containing free halogen In many processes, for example the halogenation of organic compounds, there are often large amounts of hydrogen halide, especially hydrogen chloride, which are contaminated by halogen, in particular by chlorine. These amounts of hydrogen halide but are difficult to recycle because of their free halogen content.

Es wurde nun gefunden, daß sich diese freies Halogen enthaltenden Halogenwasserstoffe technisch gut verwerten lassen, wenn man diese in eine gesättigte Cuprohalogenidlösung einleitet, wobei das freieHalogen unter Bildung von Cuprihalogenid gebunden wird.It has now been found that these contain free halogen Let hydrogen halides technically utilize well if you convert them into a saturated one Introduces cupric halide solution, with the free halogen under formation of cupric halide is bound.

Die Cuprihalogenidlösung kann dann in bekannter Weise als Halogenüberträger für die Halogenierung, insbesondere organischer Verbindungen, verwendet werden. Beispiel In einen Reaktionsturm, der eine auf zoo°C erwärmte Lösung von 490 g = 5 Mol Kupfer(I)-chlorid in 2000 g 25 °/oiger Salzsäure enthält, werden von unten 5oo NI durch Chlor (o,2 g/1) verunreinigten Chlorwasserstoffs eingeleitet. Der oben anfallende Chlorwasserstoff ist völlig frei von Chlor.The cupric halide solution can then be used in a known manner as a halogen carrier for the halogenation, in particular of organic compounds. EXAMPLE In a reaction tower containing a solution of 490 g = 5 mol of copper (I) chloride in 2000 g of 25% hydrochloric acid heated to zoo ° C, 500 NI (0.2 g / l) of chlorine are added from below. initiated contaminated hydrogen chloride. The hydrogen chloride produced above is completely free of chlorine.
