Abstract
The kinetics of the oxidation of acetaldehyde by octacyanomolybdate(V) ions in aqueous alkaline medium has been studied. The reaction display zero-order kinetics in [Mo(CN) 3–8 ] and is first order in [CH3CHO]. An acetaldehyde-dependent reaction rate constant, \(k_{{{\text{CH}}_{3} {\text{CHO }}}}\) = 1.41 ± 0.03 × 10−5 s−1 has been observed at pH 9. A significant dependence on [OH−] has been observed, and a value pKb = − 0.40 ± 0.02 for the deprotonation of the hydrated form of acetaldehyde has been obtained. Activation parameters for the reaction have been obtained, and a reaction mechanism is proposed.
