    Abstract

    We have synthesised a diazonium ion starting from 2-chloro-5-aminobenzyl alcohol, and investigated in detail its thermal stability. The DSC runs at seven different heating rates give evidence of a single decomposition reaction occurring around 90-120 °C, whose kinetics were analysed by both the iso-conversional differential and integral method, the invariant kinetic parameters method, Kissinger's method, and a differential isothermal method. All of these methods led to similar values for the kinetic parameters and showed that the first-order mechanism fits the data best. The values of the kinetic parameters were further used for calculating the half-life time of the ion at various temperatures. The result of the stability prediction at 60 °C was compared with that of an analytical isothermal test yielding a good agreement between prediction and experiment. © 2002 Elsevier Science Ltd.
