A process is disclosed for purifying an impure HCl containing at least one saturated or olefinic impurity of the formula CaHbClcFd (wherein a is an integer from 1 to 4, b and c are each integers from 0 to 9, and d is an integer from 1 to 10; provided b + c + d = 2a + 2 for acyclic compounds and b + c + d = 2a for cyclic compounds and olefinic compounds) which comprises the step of contacting the impure HCl with a sorbent for said impurities selected from activated carbons and inorganic molecular sieves (e.g., silicalites and zeolites) at a temperature and a pressure suitable for sorption for a period of time sufficient to remove a substantial amount of said impurities. |
