The Invention provides a process for the recovery of gaseous HCl comprising: a) providing an HCl-carrying extractant comprising: (i) an oil soluble amine which amine is substantially water insoluble both in free and in salt form; and (ii) a solvent for the amine and organic acid; b) contacting the HCl-carrying extractant with at least one non-volatile mineral acid, and c) stripping gaseous HCl, whereby HCl-depleted extractant and gaseous HCl are formed. |
