Abstract

The thermal decomposition of K3[V(CO3)O(O2)2] was studied under isothermal, dynamic and quasi-isobaric-isothermal condition. A mixture of K4V2O7 and K2CO3 was identified as the primary product of thermal decomposition. Under experimental conditions not allowing a continuous loss of volatile products, the reaction of K4V2O7 with CO2 gives KVO3 and K2CO3.

Zusammenfassung

Unter isothermen, dynamischen und quasi-isobaren Bedingungen wurde die thermische Zersetzung von K3[V(CO3)O(O2)2] untersucht. Als Primärprodukt der thermischen Zersetzungsreaktion wurde ein Gemisch aus K4V2O7 und K2CO3 festgestellt. Wird unter experimentellen Bedingungen das Entweichen flüchtiger Produkte verhindert, so gibt die Reaktion von K4V2O7 mit CO2 die Produkte KVO3 und K2CO3.
