Abstract

Solid complexes of RE(NO3)3(Sm, Tb) and aspartic acid were prepared for the first time in aqueous solution. Based on chemical analysis, elemental analysis and IR spectra, the formulae of the complexes were determined as RE(NO3)3(Asp)2·2H2O (RE=Sm or Tb,Asp=Aspartic acid). Their thermal decomposition mechanism were studied from ambient temperature to 700°C using a linear heating program. The study indicates that the courses of thermal decomposition of the two complexes are very similar.

Zusammenfassung

Erstmals wurden in wäßriger Lösung Feststoffkomplexe von RE(NO3)3(Sm, Tb) und Asparaginsäure hergestellt. Anhand chemischer Analyse, Elementaranalyse und IR-Spektren wurden die Formeln dieser Komplexe mit RE(NO3)3(Asp)2·2H2O (RE=Sm oder Tb,Asp=Asparaginsäure) bestimmt. Unter Verwendung eines linearen Aufheizprogrammes wurden deren thermischer Zersetzungsmechanismus zwischen Raumtemperatur und 700°C untersucht. Die Untersuchungen ergaben, daß die Reaktionswege der thermischen Zersetzung für die zwei Komplexe sehr ähnlich sind.
