Abstract

The title compounds were studied by thermogravimetry and differential thermal analysis in flowing dry air, in the temperature range 25–500°C, at a heating rate of 4 deg·min−1. Thermal analysis revealed two principal effects: dehydration, with the probable formation of a monohydrate, and oxidation of the oxalate ion at around 400°C.

Zusammenfassung

Die Titelverbindung wurde mittels TG und DTA in strömender trockener Luft im Temperaturbereich 25–500°C und einer Aufheizgeschwindigkeit von 4 deg/min untersucht. Die Thermoanalyse ergab zwei grundlegende Effekte: die Dehydratation mit der möglichen Bildung von Monohydrat und die Oxidation des Oxalat-Ions bei etwa 400°C.
