ABSTRACT:
Side reactions in the use of gaseous chlorine are avoided by leading the chlorine containing at least 0.0001% of non-volatile compounds such as ferric chloride over silica gel, glass wool, pumice or montmorillonite. Preferably the thus treated chlorine is passed through hexachlorobutadiene or perfluorokerosene in a second absorption step. Ferric chloride can also be removed from the chlorine gas by treating with sulfuric acid.
