摘　　要：通过TLC检测、FTIR、XRD、UV-Vis及NMR等多种表征方法研究了硫酸锆与甘油的相互作用,结果表明:在低p H值(<1)下,甘油与Zr(IV)发生配位形成五元环螯合物,产物结构稳定且有较好晶型,不溶于常见有机溶剂却可以溶解在10%小苏打水溶液中,溶解过程部分配位作用解除,释放出少量甘油而Zr(IV)却不发生水解。We have studied the interaction between zirconium sulfate and glycerine by a series of characterization methods, such as Thin-layer chromatography, Fourier Transform infrared spectrometry, X-ray diffraction, UV-Visible absorption spectrometry （UV-Vis） and Nuclear Magnetic Resonance and so on. The results show that, at low pH （〈1）： Zirconium sulfate can coordinate with glycerine, forming the corresponding five-member ring chelate, which has stable ？ structure and good crystal form. Moreover, the products are not soluble in common organic solvents, but can dissolve in 10wt% sodium bicarbonate solution, and in the dissolution process partial coordination roles released, which wouldn＇t cause solution hydrolysis of Zr（Ⅳ）.
