正烷基单胺对层状甘氨酸-N，N-双甲基膦酸锆的插层

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 ℃.     

结晶度对ZGDMP-Pd催化剂加氢活性的影响

首次制得不同结晶度的晶态,半晶态和无定形甘氨酸－Ｎ－Ｎ双亚甲基磷酸锆载体和相庆的钯催化剂ＺＧＤＭＰ－ＤＰｄ,用ＩＲ,ＸＲＤ,ＸＰＳ对它们进行了表征。测定了三种催化剂在常压下进行加氢反应的催化活性。
