The oxidation of hydrogen chloride gas by atomospheric oxygen in the presence of \(Cucl_{2}\) catalyst at 723K liberates

How is hydrogen chloride gas dried ?

Chlorien gas is manufactured by oxidizing hydrogen chloride gas with oxygen in the presence of cypric chloride (catalyst) heated to 400^(@) . This process is known as:

Phenol on hydrogenation in the presence of nickel catalyst at 160^(@)C gives
