ABSTRACT:
A process for producing chlorine from ammonium chloride which comprises vaporizing ammonium chloride, contacting the vapors with a metal selected from the group consisting of tin, zinc and cadmium whereby a metal chloride is formed and then electrolyzing the metal chloride in the presence of a fused salt electrolyte. The ammonium chloride is preferably obtained from the Solvay soda ash process and the process for producing chlorine is integrated with the Solvay process. The integrated process produces chlorine at a substantial energy savings and without calcium chloride being produced as a by-product.
