Abstract

The thermal decomposition characteristics of the ternary mixed, solid, primary aliphatic amine complexes formed with nickel(II) chloride was investigated by a simultaneous TG-DTG-DTA method.

The course of the thermal decomposition is described in detail, results thus obtained are compared with the literature data and contradictions are pointed out.

In addition to the complexes described in previous papers some new compounds and thermal intermediates have been prepared by solid-gas phase chemisorption and by freezing-out technique. Thermal intermediates containing two-third mole of the ligands, characteristic of the decomposition of pyridine type complexes of transition-metal halides, were identified during the degradation process.

Zusammenfassung

Mittels simultaner TG-DTG-DTA wurden die Merkmale der thermischen Zersetzung von Nickel(II)-komplexen mit gemischten ternären, festen und primären aliphatischen Aminen untersucht.

Der Reaktionsweg der thermischen Zersetzung wird eingehend beschrieben, die so erhaltenen Ergebnisse wurden mit Literaturangaben verglichen und auf Widersprüche hingewiesen.

Zusätzlich zu den in vorangehenden Arbeiten beschriebenen Komplexen wurden mittels Feststoff-Gasphasen Chemisorption und Ausfrierungstechnik einige neue Verbindungen und Thermoindermediäre hergestellt. Während des Abbauprozesses wurden Thermointermediäre mit zwei Drittel Mol Liganden beobachtet, die charakteristich für die Zersetzung der Pyridinkomplexe von Übergangsmetallhalogeniden si
