Thermogravimetric techniques have been used to study the kinetics of thermal deamination of tris(ethylenediamine)nickel(II) sulphate. The complex was synthesized and characterized by various chemical and spectral techniques. Thermal decomposition studies were carried at different heating rates (5, 10, 15 and 20°C min−1) in dynamic air. The complex undergoes a four-stage decomposition pattern. The stages
热重技术已用于研究三(乙二胺)镍(II)硫酸盐热脱氨的动力学。该复合物通过各种化学和光谱技术合成并表征。在动态空气中以不同的升温速率(5、10、15和20°C min -1)进行热分解研究。该配合物经历四阶段分解模式。这些阶段没有很好地解决。分解路径可以解释为两阶段的脱氨和两阶段的分解。分离并通过IR和XRD鉴定每个阶段的反应产物。借助SEM研究了配合物和残留物的形态。发现分解的最终残余物是结晶NiO。
