The position of the equilibrium in the PTC exchange reaction of alkyl chloride with metal bromide salts RCl + MBr ⇌ RBr + MCI under various condtions is utilized for calculation of the selectivity constant K sel Cl/Br . This constant is found to be dependent on the nature of the metal cation and the inorganic phase composition. K sel Cl/Br can be defined for any point on the phase diagram MCl—MBr—H 2 O at a given temperature, solvent and quaternary cation.
