Abstract
Cyclohexene can be advantageously separated from a mixture containing as main components benzene, cyclohexene and cyclohexane by a process wherein said mixture is brought into contact with a type X aluminosilicate zeolite, which has been ion-exchanged with a silver ion, as an adsorbent, whereby cyclohexene is selectively adsorbed thereon, and then, cyclohexene is desorbed therefrom. The desorption of cyclohexene is preferably carried out by using a desorbent, such as an alkylbenzene having 7 or 8 carbon atoms in the molecule.
