摘要： The process according to the invention comprises bringing gaseous hydrogen chloride in a non-condensable gas into contact with an absorbing medium selected from water or a dilute aqueous hydrogen chloride solution in an absorption column to cause the medium to absorb the gaseous hydrogen chloride, and subjecting the resultant absorbed solution to distillation in the presence of a salt having a salting-out effect to produce anhydrous hydrogen chloride.
