Abstract

Quinoxaline-2-carboxalideneglycine complexes of iron(III), cobalt(II), nickel(II) and copper(II) complexes were subjected to a systematic TG/DTG analysis. The decomposition process consists of two stages for all these complexes. Kinetic parameters were evaluated for each of these stages using the Coats-Redfern equation. The rate of decomposition at the second stage seems to have a bearing on the catalytic effect of the metal oxides formed during this stage.

Abstract

Комплексы хиноксалин-2-карбоксалиденглицина с железом(III) ковальтом(II), никелем(II) и медью(II) были подвергнуты систематическому анализу ТГ/ДТГ. Процесс разложения для всех комплексов состоит из двух стадий. На основе уравнения Котс-Рэдферна были рассчитаны кинетические параметры каждой ступени. Скорость разложения на второй стадии, по-видимому, оказывает влияние на каталитические свойства окислов металла, образующихся на этой стадии.
