ABSTRACT:
A method for the recovery of anhydrous aluminium chloride from a mixture of the aluminium chloride with ferrous chloride or ferric chloride, or both, which comprises subjecting the liquid mixture to a reduction in pressure, the conditions being such as to bring about dissociation of compounds of aluminium chloride and ferrous chloride present in the mixture, thereby to form an aluminium chloride-rich vapour and an iron chloride-rich solid and then separately collecting of the iron-and aluminium-rich components under conditions which give the minimum opportunity for recombination.
