Description

Kinetics of the isotopic H-D exchange in aniline and n-toluidine between hydrogen atoms of amino-group and aromatic ring is studied by the method of paramagnetic resonance spectroscopy. Rate constants and activation energies of hydrogen regrouping are determined in dependence on temperature. It permits to control the position and multiplicity of tritium label in aromatic amines during their continuous storage

Abstract (Russian)

Методом спектроскопии парамагнитного резонанса изучена кинетика изотопного обмена H-D в анилине и n-толуидине между водородными атомами аминогруппы и ароматического кольца. Оперелены константы скорости и энергии активации водородных перегруппировок в зависимости от температуры. Это позволяет контролировать местонахождение и кратность тририевой метки в ароматических аминах в условиях их длительного хранения
