Abstract

The chemical effect of a hydrogen bond of increased strength responsible for the existence of H3O −2 and determining mainly the Ea of the catalytic isotope exchange (IE) of hydrogen with water-alkaline solutions (WAS) is discussed. Assuming that the H3O −2 associates are also effective in the case of water-alkaline melts (WAM), experimental kinetic evidence in favor of the suggested treatment of the IE mechanism is considered.

Abstract

Обсуждается химическое проявление водородной связи повышенной прочности, обуславливающей существование H3O −2 и в основном определяющей Ea каталитического изотопного обмена (ИО) водорода с водощелочным раствором (ВЩР). В предположении проявления H3O −2 -ассоциатов и в случае водощелочных расплавов (ВЩРпл) рассматриваются экспериментальные кинетические свидетельства в пользу предлагаемого истолкования механизма ИО.
