Abstract

The thermal decomposition of the acetates of calcium, sodium, silver and copper(II) have been investigated using thermogravimetry and differential thermal analysis, together with analysis of the gaseous products formed during the decomposition process. The results indicate that the major organic product formed is either acetone or acetic acid, depending on whether the final solid product is the oxide or the metal.

Résumé

On a étudié la décomposition thermique des acétates de calcium, sodium, argent et cuivre(II) par thermogravimétrie et analyse thermique différentielle, en effectuant également l'analyse des produits gazeux formés. Les résultats indiquent que le principal produit organique formé est l'acétone ou l'acide acétique, suivant que le produit final solide est l'oxyde ou le métal.

Zusammenfassung

Unter Anwendung der Thermogravimetrie und der Differential-Thermoanalyse, in Verbindung mit der Analyse der wÄhrend der Zersetzungsvorganges entstehenden gasförmigen Produkte, wurde die thermische Zersetzung der Acetate von Kalcium, Natrium, Silber und Kupfer(II) untersucht. Die Ergebnisse zeigen, da\ — in AbhÄngigkeit davon, ob das feste Endprodukt das Oxid oder das Metall ist, das organische Hauptprodukt entweder Aceton oder EssigsÄure ist.
