Abstract
This invention comprises a process for separating 3,5-diethyltoluene from a feed mixture comprising 3,5-diethyltoluene and at least one isomer thereof, which process comprises contacting the mixture at adsorption conditions with an adsorbent comprising an X zeolite cation exchange with a K cation, thereby selectively adsorbing the 3,5-diethyltoluene. The remainder of the feed mixture is removed by desorption at desorption conditions with a desorbent material comprising a monocyclic alkyl-substituted aromatic hydrocation, e.g., p- or m-diethylbenzene or p-cymene and optionally, a diluent, e.g., isooctane.
