  Verfahren zur   Herstellung   arsenfreier Salzsäure. 
 EMI1.1 
 fläehe der   Füllkörper   ein Teil der Gase kondensiert und dieser kondensierte Anteil aus dem ankondensiert bleibenden Teile das Arsen herauslöst. Auf diese Weise wird die   Gesamtmenge   der   ChJorwasserstoffgase   in einen arsenreichen und einen arsenarmen Teil zerlegt. Es gelingt jedoch nach diesen) Verfahren der nassen   Wäsehe   des chlorwasserstoffgases mittels wässeriger Salzsäure, wobei der Koks nur die Rolle eines spröden, von Salzäure nicht angreifbaren Föüllkörpers spielt, nicht, eine   voHständig arsenfreie   Salzsäure zu erzielen. 



   Es wurde nun gefunden, dass arsenhaltige rohe Salzsäure beliebiger Konzentration von ihrem Arsengehalt, einerlei ob derselbe relativ gross oder klein ist, leicht vollständig berfreit werden kann, wenn

 leicht wieder regeneriert werden.

  Process for the production of arsenic-free hydrochloric acid.
 EMI1.1
 If the filler body condenses part of the gases and this condensed part dissolves the arsenic from the parts that remain condensed. In this way, the total amount of hydrogen chloride gases is broken down into an arsenic-rich and an arsenic-poor part. However, according to this process of wet washing of the hydrogen chloride gas by means of aqueous hydrochloric acid, the coke only playing the role of a brittle filling body that cannot be attacked by hydrochloric acid, it is not possible to achieve completely arsenic-free hydrochloric acid.



   It has now been found that arsenic-containing crude hydrochloric acid of any concentration can easily be completely freed from its arsenic content, regardless of whether it is relatively large or small, if
 EMI1.2
 can be easily regenerated.
