摘要 研究了固相研磨法在制备金属有机配合物中的应用,采用室温固相研磨法一步合成得到对氨基苯甲酸铜(Ⅱ)配合物。借助元素分析、粉末X射线衍射、红外光谱以及热分析技术对产物进行结构表征,确定对氨基苯甲酸铜(Ⅱ)配合物的分子结构为Cu(p-NH2C6H4COO)2。采用基于扫描电镜的显示液相法、固相研磨法和添加表面活性剂PEG400进行研磨,得到对氨基苯甲酸铜(Ⅱ)配合物的形貌分别为仙人球型、团絮状和棒簇状。研究结果表明:固相研磨法在反应时间和收率上都明显优于液相法。 To investigate the application of grinding in the preparation of metal-organic complexes, copper (II) complex with p-aminobenzoic acid derived from cupric acetate monohydrate and p-amino- benzoic acid was prepared by one-step solid-state reaction at room temperature. The molecular struc-ture [ Cu (p-NH2C6H4COO)2 ] was determined by elemental analyses, powder X-ray diffraction ( XRD), fourier transform infrared spectroscopy (FI'IR) and thermogravimetric analysis ( TG-DSC ). Cactus, flocculent and clusters of rods shape Cu (II) complex, which determined by scanning electron microscope(SEM), was obtained through liquid phase, grinding and in the presence of a suitable nonionic surfactant PEG400 when grinding, respectively. Meanwhile, the result shows that the reac- tion time and yield of grinding are significantly better than the liquid phase method.
