Abstract

A pulse reaction technique has been shown to be applicable to study the kinetics of the catalysis over liquid indium. By using this technique, kinetic isotope effects in the catalytic dehydrogenations of ethyl alcohol and isopropyl alcohol over liquid indium have been measured at 460 °C to obtain Xdo Xd1, = 1.62, Xd1 Xd6 = 1.20 for ethyl alcohol and Xdo Xd1 = 1.71, Xd1 Xd8 = 1.19 for isopropyl alcohol (X denotes the conversion of alcohol and the subscript dn indicates a deuterium content in the reactant alcohol). It has been proved that these results are able to be explained in terms of the previously proposed reaction mechanisms. Further, a plausible model of the activated complex has been proposed on the basis of the observed isotope effect.
