有机-无机杂化磷酸锆及胺插层化合物的MAS NMR 研究

The layered zirconium [N-(phosphonomethyl)iminodiacetic acid-phosphate] Zr(HPO₄)_1.34[O₃PCH₂N-(CH₂CO₂H)2]_0.66·H₂O can only be prepared in the series of the zirconium phosphonate-phosphates Zr(HPO₄)_2-x[O₃PCH₂N(CH₂CO₂H)₂]_x·H2O (ZPPMIDA) by the reaction of zirconium oxychloride with phosphonic acid and H₂O₃PCH₂N(CH₂CO₂H)₂ in the designed x range of 0 < x < 2, which had been monitored by using the phosphorus integration value ratio of HPO₄^2- and [O₃PCH₂N(CH₂CO₂H)₂]^2- group in the ³¹P MAS NMR spectra. After intercalation of n-butyl amine, the ³¹P chemical shift of HPO₄^2- group at -8.0~-10.0 ppm moved to 6.0 ppm with a change of 14.0~16.0 ppm and that of [O₃PCH₂N(CH₂CO₂H)₂]^2- group at -29.1 ppm changed only 0.5 ppm. Due to the pillared effect of [O₃PCH₂N(CH₂CO₂H)₂]^2- groups on the interlayer spacing, intercalated amines such as n-butylamine, n-hexyl amine and n-octyl amine easily reacted with HPO₄^2- group in ZPPMIDA (x=0.66) rather than that in α-ZrP, and carboxylic group (-CO₂H) in ZPPMIDA (x=0.66).
