The isotopic exchange of gaseous hydrogen with liquid ammonia was studied by using deuterium hydride, tritium hydride, and deuterium. It is catalyzed by alkali amides. The dependence of its rate on the concentration and the type of the catalyst, on the exchanging hydrogen, and on the temperature was measured. Catalysis was found to be due to free amide ion and to undissociated alkali amide. The activation energy is 7.5 kcal/mole. The isotope effects found are analyzed and shown to be consistent with a two-step mechanism in which an iatermediate complex, composed of a hydrogen, a catalyst, and a solvent molecule, participates.
