晶态层状N,N-二乙酸亚氨基亚甲基膦酸-磷酸氢锆的制备及插层研究

Study on the preparation and intercalation behavior of layered crystalline zirconium phosphate-phosphonate

采用氢氟酸络合法合成了结晶度高的N,N 二乙酸亚氨基亚甲基膦酸 磷酸氢锆 (α ZPPMIDA) 层状晶体,层间距为 1. 477nm。研究了正丁胺对α ZP PMIDA的插层反应, 用 IR、XRD、TG DSC热分析和元素分析对该插层复合物进行了表征。结果表明正丁胺在主体底物中呈双分子层,层间距增大了0.847nm。

Layered crystalline sample of Zr(HPO4)1.35[O3PCH2 N(CH2COOH)2]0.65 &middot H2O (crZPPMIDA) was prepared with zirconium oxychloride, phosphoric acid and H2O3PCH2 N(CH2COOH)2 (PMIDA) in the presence of hydrofluoric acid. The product was highly crystalline with an interlayer spacing of 1.477 nm. n-Butylamine had been intercalated into crZPPMIDA at room temperature. α-ZPPMIDA and its intercalation complex crZP-PMIDA-BA were characterized by IR, XRD, TG-DSC and element analysis. These results showed the interlayer spacing increased 0.847 nm with the intercalation of n-butylamine.
