混合型甘氨酸-N,N-双亚甲基膦酸-磷酸锆:合成、表征及插层

摘要

Two a、y-mixed layered zirconium glycine-/V, ,/V-dimethylphosphonate phosphates, Zr(PO4)0.41(HP04)0.043 [(O3PCH2)2NCH2COOH]067H2O(l)and Zr(P04)o.2i(HP04)o.o38[(O3PCH2)2NCH2COOH]o.82-2H2O (2), were synthesized by the reaction of zirconium oxychloride with glycine-A', iV-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.%采用氢氟酸络合法,在npZr=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.
