摘要: 钴氰配合物的合成、结构和催化性能巳有不少研究[1-11],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。

Abstract: Thermal decomposition of the title compounds(L=NO-, CN-, NO2-, N3-)in heliumand vacuum has been studied by gas chromatography and quadrupole mass spectrometry. Theresult shows that the substitute ligand released prior to cyano group and the order of thedecomposition temperature of substituted ligands is NO- < N3- < NO2- < CN-. Appearance of potassiun cyanocobaltate(Ⅲ)in decomposition products shows a rearlan-gement occured among solid. compounds during the decomposition reaction.

Key words: solid reaction, coordination chemistry, cobaltic pentacyanide complex, thermal decomposition
