Abstract
Process for de-halogenating material contg. cpds. in a soln. or in gaseous form of organo-halogens, involves bringing the material to be treated into contact with particles of an inert solid material which contains sodium or potassium. The material to be treated is held at a temp. of between 20 and 160 deg. C pref. between 40 and 120 deg. C and together with the treatment medium is poured through a chute made from a material which is resistant to alkalis or alkali metals. This treatment lasts for between 120 min and 1 min but preferably between 60 min and 10 min..
