Abstract
The kinetics of the oxidation of Mo(CN) 4−8 by IO −4 has been studied in ethanol—water solvent mixtures over a temperature range of 15–35 °C. The effect of solvent composition on the reaction rate and the mechanism has been investigated. Activation parameters are given. An inner-sphere mechanism, consistent with the kinetic results, is proposed.
Zusammenfassung
Die Kinetik der Oxidation von Mo(CN) 4−8 mit IO4/− wurde in Ethanol—Wasser über einen Temperaturbereich von 15–35 °C untersucht. Der Effekt der Lösungsmittelzusammensetzung auf die Reaktionsgeschwindigkeit und der Mechanismus der Reaktion werden diskutiert. Die Aktivierungsparameter sind angeführt. Es wird ein „Inner-Sphere“-Mechanismus vorgeschlagen, der mit den kinetischen Ergebnissen konsistent ist.
