Abstract

18 monobasic complex acids of the type H[Co(DH)2XY] (X, Y=Cl, Br, I, NO2, N3, NCS, NCSe, CN), or their alkalimetal and ammonium salts, and 5 aquo-acido-nonelectrolytes, [Co(DH)2(H2O)X] (DH=deprotonated dimethylglyoxime), were obtained and their thermal decompositions were studied by means of TG and DTA. The thermolysis processes are discussed. Kinetic parameters have been derived for several decomposition stages and are discussed in terms of the kinetic compensation effect.

Zusammenfassung

18 monobasische Komplexsäuren des Typs H[Co(DH)2XY] X, Y=Cl, Br, I, NO2, N3, NCS, NCSe, CN) oder deren Alkalimetall- und Ammoniumsalze und 5 Aquoacido-Nichtelektrolyte [Co(DH)2(H2O)X] (DH=deprotoniertes Dimethylglyoxim) wurden hergestellt. Die thermische Zersetzung dieser Verbindungen wurde mittels TG und DTA untersucht. Die Thermolyseprozesse werden diskutiert. Kinetische Parameter wurden für verschiedene Zersetzungsstufen ermittelt und werden in Verbindung mit dem kinetischen Kompensationseffekt diskutiert.
