The layered zirconium glycine-N,N-dimethylphosphonate (ZGDMP) was prepared and the intercalation behavior of n-alkylmonoamines was investigated. The X-ray diffraction powder patterns demonstrated that the n-alkylmonoamines were taken up in one step and there were no other intermediate phases. The interlayer distance correlated with the number of carbon atoms of the n-alkylmonoamine chains. The n-alkylmonoamines were intercalated into ZGDMP in such a way that the protons of the interlayer -CO2H groups were replaced by the terminal -NH3+ of the protonated n-alkylmonoamines. The intercalated n-alkylmonoamines were released from the lamellar ZGDMP at temperature of 150 to 250 ℃. 相似文献

微波辐射固相法合成缩二脲铜配合物 总被引:5,自引:0,他引:5
The copper(Ⅱ) complexes of biuret have been synthesized by solid phase reaction with microwave irradiation. The compositions and structures of the complexes are characterized by elemental analysis, molar conductance, in-frared spectra, electronic spectra, magnetic susceptibility, thermogravimetric and differential thermal analysis, X-ray powder diffraction. The two complexes have the compositions of [Cu(bi)2]Cl2(A) and [Cu(bi)2](NO3)2(B)(bi=NH2CONHCONH2) and the molecular formulae of CuC4H10O4N6Cl2 and CuC4H10O10N8, respectively. The molar conductance data show that the complexes are 1∶2 electrolyte. Infrared spectra of the complexes show oxygen atoms have been coordinated with divalent copper ion. The thermal decomposition processes of the complexes show that the final residues are all cupper oxide. The results of indexes to the X-ray powder diffraction data indicate that the crystal structure of the complexes belong to monoclinic system, the lattice parameters are: a=0.6976nm,b=1.1546 nm,c=2.1689nm,β=96.80°,V=1.7346nm3 for A; and a=0.7096nm,b=1.1359 nm,c=2.1002 nm,β=97.05°,V=1.6800nm3 for B, respectively. 相似文献
