ABSTRACT:
There is provided a method for the selective sorption of n-alkylbenzene, such as n-propylbenzene, from an alkylbenzene mixture, such as a mixture of n-propylbenzene and isopropylbenzene, with an oxide impregnated ZSM-5 sorbent. This method may be particularly useful in the purification of cumene product streams.
