摘要
本文用气相色谱、质谱法研究了双核配合物[Co(NH_3)_5H_2O][M(CN)_6](M=Co,Fe)的热分解反应,直接测量到多种气相产物并分别计算了各平行反应的热分解动力学参数,结果与前人用TGA、DSC等方法推测出的气相产物及计算出的动力学参数不一致.发现这类配合物的热分解反应过程并非单一反应,而是由连串反应和平行反应构成的复杂反应.
The thermodecomposition of two dinuclear coordination compounds, C Co(NH3)5H2O] CM(CN)6] (M = Co,Fe) is studied by use of Gas-chromatography and Mass Spectrometer. The gas products are detected directly and kinetic parameters are calculated. The results differ from that obtained by TGA and DSC methods. So some complex reaction routine re suspected for this kind of compounds such as parallel and conscutivc reactions.
