The Gross-Butler theory for the solvent isotope effect of deuterium on acid-catalyzed reaction rates in thermodynamic activity function, Q' (n), for proton and deuteron at 25 deg are derived from experimental data by using the correct value for the i

Deuterium gas exchanges slowly with liquid methanol over Raney nickel catalyst at 35 deg . The reaction is zero order with respect to deuterium pressure and has a low activation energy. The influences of catalyst weight, catalyst treatment, and of th
