Abstract

The thermal decomposition of anhydrous fluoroborates MBF4 (M=Li, Na, K, Rb, Cs) and M(BF4)2 (M=Ca, Sr, Ba) was investigated. The decomposition proceeds according to a simple acid-base mechanism with evolution of BF3. The influence of the acidity of cationic counterions, expressed by the electronegativity force on the course of thermal decomposition was estimated quantitatively.

Zusammenfassung

Es wurde die thermische Zersetzung der wasserfreien Fluoroborate MBF4 (M=Li, Na, K, Rb, Cs) und M(BF4)2 (M=Ca, Sr, Ba) untersucht. Die Zersetzung verläuft gemäß eines einfachen Säure-Basen-Mechanismus unter Freisetzung von BF3. Der Einfluß der durch die Elektronegativität ausgedrückten Acidität des kationischen Gegenions auf den Weg der thermischen Zersetzung wurde quantitativ abgeschätzt.
