Abstract: | Thermal deoxygenation under vacuum has been examined for free oxygenated cobalt complexes formed with phenanthroline, histidine, and histamine and also for those attached to aerosil; mass spectrometry has been applied to the products. The free compounds are deoxygenated in accordance with the Roginskii equation f() = (1–)2/3 in a certain range. Deoxygenation for the grafted complexes is described by an equation for nucleation and one-dimensional growth f() = 1–. The kinetic parameters have been determined.Translated from Teoreticheskaya i Éksperimental'naya Khimiya, Vol. 23, No. 3, pp. 311–317, May–June, 1987. |
