钴氰配合物的合成、结构和催化性能巳有不少研究,但热稳定性方面还很少报道,本文用气相色谱和四极质谱研究了3个一取代五氰合钴酸钾配合物的热分解过程,对分解时放出的气体产物用色谱、质谱进行了跟踪检测,对应各阶段的固相产物分别用红外和X-衍射谱进行了标识。实验结果表明这类配合物的热稳定性次序为:
Many studies have been made on the synthesis, structure and catalytic properties of cobalt cyanide complexes, but little is reported on the thermal stability. In this paper, the gas chromatography and quadrupole mass spectrometry were used to study the structures of three monosubstituted potassium pentacyano-cobaltate complexes Thermal decomposition process, the decomposition of gas products released by chromatography, mass spectrometry were followed detection, corresponding to the various stages of solid-phase products were identified by infrared and X-ray diffraction. The experimental results show that the thermal stability of these complexes in the order:
