Kinetics of cis-2-butene isomerization were studied on pure and chlorinated aluminas. The surface reaction is rate controlling and produces trans-2-butene and 1-butene by two parallel reactions. The variations of catalytic activity with chlorine content support the existence of different types of sites; at least three kinds of active sites are proposed: oxygen ions having electron donor properties, weakly basic sites, and strong Lewis centers.
