ABSTRACT:
Disclosed is a method to be practiced in a gas purification apparatus that is suitable for contacting a chlorine-containing mixture of gases with carbon tetrachloride in order to remove one of the gases from the mixture. The gas removed can be either chlorine or another gas such as nitrogen trichloride. In the method of the invention, one of the gases is removed from the mixture in that apparatus without using carbon tetrachloride by contacting the chlorine-containing gas mixture in the apparatus with a chlorinated organic liquid which can either be chloroform or ethylene dichloride.
