In one of our previously published articles, we reported the synthesis, spectroscopic, thermal, and catalytic properties of four new M(II) acetate (where M = Co, Ni, Cu, Zn) complexes with imidazole. Presented compounds exhibited activity in the reaction on catalytic oxidation of styrene. In this study we have synthesized and investigated properties of analogous compounds, however using formates or propionates of mentioned metal cations instead of acetates. Such an approach allowed us to draw valuable conclusions concerning the relationship between the carbon chain length and catalytic activity, which is an important factor for catalyst modeling. Synthesized compounds have been thoroughly investigated using appropriate analytic techniques: AAS (Atomic Absorption Spectrometry), FTIR (Fourier-Transform Infrared Spectroscopy), and TGA (Thermogravimetric Analysis). Catalytic properties have been studied under the same previous conditions, using GC-FID (GC-chromatograph equipped with FID detector).
在我们之前发表的一篇文章中,我们报道了四种新的含咪唑的M(II)醋酸盐(其中M = Co、Ni、Cu、Zn)配合物的合成、光谱、热性质和催化性质。所呈现的化合物在苯乙烯催化氧化反应中表现出活性。在本研究中,我们合成并研究了类似的化合物,不过使用的是上述金属阳离子的甲酸盐或丙酸盐而非醋酸盐。这种方法使我们能够就碳链长度与催化活性之间的关系得出有价值的结论,而这是催化剂建模的一个重要因素。已使用适当的分析技术对合成的化合物进行了全面研究:原子吸收光谱法(AAS)、傅里叶变换红外光谱法(FTIR)和热重分析法(TGA)。在与之前相同的条件下,使用配备氢火焰离子化检测器(FID)的气相色谱仪(GC)研究了催化性质。
