Abstract

Catalytic hydrogen exchange has been studied between ethane and deuterium as well as tritium labeled hydrogen on nickel catalyst. A comparison of ratio of the initial rates obtained by using tritium and deuterium labelled hydrogen to that of tritium to deuterium in hydrogen gas showed that there is no kinetic isotope effect with resepct to the hydrogen isotopes. The simultaneous investigation of H2—D2 exchange on the same catalyst shows that the rate of H2—D2 conversion is much higher than that of hydrogen exchange in ethane; therefore, the experimental fact found for the kinetic isotope effect by using heavy and light hydrocarbons is correct and it is not influenced by the difference in the bond strength between Ni—H and Ni—D.
