Action of Hydrochloric acid gas with oxygen

Answer 1

Deacon process is the preparation of chlorine gas using hydrochloric acid gas with oxygen using a catalyst cupric chloride(CuCl₂)

$\underset{\mathrm{hydrochloride}\mathrm{gas}}{\underset{}{4\mathrm{HCl}\left(\mathrm{g}\right)}}+\underset{\mathrm{oxygen}}{\underset{}{{\mathrm{O}}_2}}\underset{723\mathrm{K}}{\overset{{\mathrm{CuCl}}_2}{\to }}\underset{\mathrm{chlorine}}{\underset{}{2{\mathrm{Cl}}_2}}\uparrow +\underset{\mathrm{water}}{\underset{}{2{\mathrm{H}}_2\mathrm{O}}}$
