研究[Cr_3(M_3-O)(M-OOCH)_6(H_2O)_2OOCH)·xH_2O[表示为(Cr_3FF)],在乙炔、水汽系统中的反应行为时发现,当温度高于220℃时,脱了部分配体的(Cr_3FF)碎片具有活化乙炔进行加氢和加水反应的性能。为进一步探讨这些活性组分,综合采用了差热分析(DTA),热重分析(TGA),高温X射线粉末衍射(HXRD)和红外光谱法(IR)对(Cr_3FF)的热解过程进行定性、定量研究。基于此,讨论了活性组分的本质。
The reaction behavior of [Cr_3 (M_3-O) (M_OOCH) _6 (H_2O) _2OOCH) · xH_2O [Cr_3FF] was studied. It was found that when the temperature was above 220 ℃, Part of the ligand (Cr_3FF) fragments activated acetylene hydrogenation and water reaction performance. In order to further explore these active components, pyrolysis of (Cr_3FF) was qualitatively characterized by differential thermal analysis (DTA), thermogravimetric analysis (TGA), high temperature X-ray powder diffraction (XRD) and infrared spectroscopy (IR) ,Quantitative Study. Based on this, the nature of the active ingredient is discussed.
