Abstract
A process for producing chlorine by reaction of gaseous hydrogen chloride with oxygen in the presence of a catalyst prepared by reaction of chromium trioxide and cerous chloride with ethanol and calcination of the resulting reaction product, or, alternatively, prepared by reaction of chromium trioxide with ethanol, and calcination and impregnation of the resulting chromic oxide with aqueous solution of cerous chloride.
