The catalytic isomerization of pentenes over KC//2//4 has been investigated. The double-bond-migration and the cis-trans isomerization took place over KC//2//4, but the skeletal isomerization was not observed. From the rates of reactions and the selectivity ratios, all six of the relative rate constants and the activation energies of reactions were determined. The reaction paths on the triangular graph calculated from the rate constants show the cis-convex type profile. The competitive isomerization of 1-pentene and 2-methyl-1-pentene has also been investigated. The rate of isomerization of 1-pentene was greater than that of 2-methyl-1-pentene, which can be explained on the basis that the amount of chemisorption of 1-pentene during the competitive reaction is greater than that of 2-methyl-1-pentene.
