A process for the recovery of hcl from a dilute solution thereof and extractant composition for use therein |
| abstract |
There is provided a process for the recovery of HCI from a dilute solution thereof, comprising bringing a dilute aqueous HCI solution into contact with a substantially water-immiscible extractant, the extractant comprising an oil soluble amine, which amine is substantially water insoluble both in free and in salt form; an oil soluble weak organic acid having a pKa above 3, which acid is substantially water insoluble both in free and in salt form; and a solvent for the amine and organic acid; whereupon HCI selectively transfers to the extractant to form an HCI-carrying extractant, and treating the HCI-carrying extractant to obtain gaseous HCI. Also provided is the extractant composition. |
