  Verfahren zum Entarsenieren von Flüssigkeiten und Gasen, insbesondere von
Schwefelsäure,   Salzsäure, Flusssäure   und SO2-hältige-Gasen. 



   Weitere Versuche mit dem Verfahren zum   Entarsenieren   von   Flüssigkeiten und Gasen   haben ergeben, dass sich die in dem Stamm-Patent genannten reinen Benzolderivate durch die reinen Derivate der aliphatischen Kohlenwasserstoffe, u.   zw.   deren Halogenverbindungen und Schwefelkohlenstoff zur Entarsenierung von   Flüssigkeiten   und Gasen ersetzen lassen. 



   Diese Körper bilden bei der   Entarsenierung   den grossen Vorteil, dass die zu entarsenierenden Produkte   gänzlich   farblos bleiben und dass die Regenerierung dieser Körper in einfachster Weise   geschehen kann.   



   Zur Entarsellierung von   Schwefelsäure   eignet sich z. B. sehr gut der Tetrachlorkohlenstoff.

  Process for dearsenating liquids and gases, in particular
Sulfuric acid, hydrochloric acid, hydrofluoric acid and gases containing SO2.



   Further experiments with the process for dearsenating liquids and gases have shown that the pure benzene derivatives mentioned in the parent patent are replaced by the pure derivatives of aliphatic hydrocarbons, u. between their halogen compounds and carbon disulfide for dearsenation of liquids and gases.



   In the case of dearsenic, these bodies have the great advantage that the products to be dearsened remain completely colorless and that these bodies can be regenerated in the simplest possible way.



   For deariselling of sulfuric acid z. B. very good carbon tetrachloride.
