    Description / Table of Contents: Abstract При окислении аминокислот хлорамином-T (CAT) в среде HCl (30°C) установлен одновременный катализ как ионами H+, так и ионами Cl− при [HCl]=0,04–0,12M. Для скорости реакции наблюдается первый порядок по [CAT], [H+] и [аргинин] и нулевой порядок по [гистидин]. Скорость реакции также зависит от [Cl−]0,7. При [HCl]〉0,12M скорость=k · [CAT][аминокислота]0,6 и не зависит от [Cl−]. Предложен возможный механизм процесса.
    Notes: Abstract The oxidation of amino acids by chloramine-T (CAT) in HCl medium at 30°C indicates simultaneous catalysis by H+ and Cl− ions in the HCl concentration range of 0.04–0.12 M. The reaction is first order with respect to concentrations [CAT], [H+] and [arginine], but zero order with respect to [histidine]. The rate depends also on Cl− concentration following 0.7th order. At HCl concentrations 〉0.12 M, the rate equation is:w=k[CAT] [amino acid]0.6 and is independent of the [Cl−]. A suitable mechanism has been suggested.
