Isomerization of cis-2-butene and trans-2-butene catalyzed by acid- and ion-exchanged smectite-type clays
Two commercial acid-activated montmorillonites were exchanged with different cations (Al3+, Cr3+, Fe3+, and Ni2+). The catalytic activity of the acid- and the ion-exchanged clays was measured using the isomerization of cis- and trans-2-butene at 300 °C to yield the corresponding isomers.
