【摘要】 采用氢氟酸络合法,在nP/nZr=2.0条件下,以甘氨酸-N,N-双亚甲基膦酸(DMPG)和H3PO4为原料,按不同投料物质的量的比制备了2个α、γ-混合型甘氨酸-N,N-双亚甲基膦酸-磷酸锆层状主体化合物Zr(PO4)0.41(HPO4)0.043[(O3PCH2)2NCH2COOH]0.67.H2O(1)和Zr(PO4)0.21(HPO4)0.038[(O3PCH2)2NCH2COOH]0.82.2H2O(2),用元素分析、X射线衍射、红外光谱、热分析、固体核磁磷谱等对化合物进行了表征,同时研究了与正丁胺客体分子的插层组装性能。更多还原

【Abstract】 Two α、γ-mixed layered zirconium glycine-N,N-dimethylphosphonate phosphates,Zr(PO4)0.41(HPO4)0.043[(O3PCH2)2NCH2COOH]0.67H2O(1)and Zr(PO4)0.21(HPO4)0.038[(O3PCH2)2NCH2COOH]0.82·2H2O(2),were synthesized by the reaction of zirconium oxychloride with glycine-N,N-dimethylphosphonate and phosphonic acid on the basis of different feeding molar ratios in the presence of HF,and were characterized by XRD,IR,TG-DSC,elemental analysis and 31P MAS NMR.The intercalation behavior with n-butylamine was also studied.更多还原
