以四极质谱法为主要手段研究了一取代基五氰合铁(Ⅱ)类配合物在真空中的热分解,结合穆斯堡尔谱结果研究了固相物的化学组成,阐明了配合物的热分解机制,并发现配合物的热稳定性顺序与取代基团的光谱化学序列一致.对该类配合物的热分解动力学研究表明,分解活化能与分解峰值温度之间存在线性关系.
The quadrupole mass spectrometry was used as the main method to study the thermal decomposition of a pentacyanoferrate (Ⅱ) complex in vacuum. The chemical composition of the solid phase was studied by Mossbauer spectroscopy. The results showed that the complex And found that the order of thermal stability of the complexes is consistent with the spectral chemical sequence of the substituted groups.The thermal decomposition kinetics of these complexes shows that there exists a linear relationship between the decomposition activation energy and the decomposition peak temperature.
