| 摘 要： | The layered zirconium N-(phosphonomethyl)iminodiacetic acid-phosphate]
Zr(HPO4)1.34O3PCH2N-(CH2CO2H)2]0.66·H2O can only be prepared in the series of the zirconium phosphonate-phosphates
Zr(HPO4)2-xO3PCH2N(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
HPO42- and O3PCH2N(CH2CO2H)2]2- group in the
31P MAS NMR spectra. After intercalation of n-butyl amine, the 31P chemical shift of
HPO42- 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
HPO42- group in ZPPMIDA (x=0.66) rather than that in α-ZrP, and carboxylic group
(-CO2H) in ZPPMIDA (x=0.66).
