Abstract

Nineteen salts of hexachloroplatinic acid with monovalent metals, aromatic and heterocyclic amines and phosphine were obtained and characterized by chemical analysis. The thermal decomposition of these complexes was studied by means of derivatograph and differential scanning calorimetry. The nature of the pyrolysis processes is discussed. From the TG curves, kinetic parameters were derived for different stages of the thermal decompositions.

Zusammenfassung

Es wurden neunzehn Salze von Hexachlorplatinsäure mit monovalenten Metallen, aromatischen und heterocyclischen Aminen und Phosphinen hergestellt und mittels chemischer Analyse beschrieben. Mittels Derivatographie und DSC wurden die thermischen Eigenschaften dieser Komplexe untersucht. Es wird die Natur des Pyrolyseprozesses diskutiert. Anhand der TG-Kurven wurden kinetische Parameter für die einzelnen Schritte der thermischen Zersetzung ermittelt.
