Abstract

Two solid copper(II) phenoxyacetates (anhydrous and dihydrate) were prepared and investigated by DSC and TG techniques. The results obtained indicated that the water molecules of the dihydrate compounds were weakly and differently bonded; also, both anhydrous and dihydrate compound decomposed with formation of CuO as final product, but by different steps. Some thermodynamic parameters associated with the observed thermal processes were evaluated and the results obtained were discussed and interpreted.

Zusammenfassung

Es wurden zwei feste Kupfer(II)-phenoxyacetate (wasserfrei und Dihydrat) hergestellt und mittels DSC- und TG-Techniken untersucht. Die erhaltenen Ergebnisse zeigen, da\ die Wassermoleküle des Dihydrates schwach und unterschiedlich gebunden sind. Sowohl die wasserfreie Verbindung als auch das Dihydrat zersetzen sich unter Bildung von CuO als Endprodukt, jedoch über unterschiedliche Schritte. Bezüglich des untersuchten thermischen Prozesses wurden einige thermodynamische Grö\en ermittelt und die erhaltenen Ergebnisse ausgewertet und interpretiert.
