Abstract
An industrially excellent method for selectively dealkylating a 1,4-dialkylbenzene in a dialkylbenzene mixture by the use of a specified zeolite catalyst is disclosed, which catalyst is a crystalline zeolite ion-exchanged with sodium ion, potassium ion, potassium ion, rubidium ion, or cesium ion. The specific zeolite catalyst is easy to prepare and allows selective dealkylation of the 1,4-dialkylbenzene and recovery of the formed olefins in a high yield and a high purity.
