AbstractThe utility of the rotating platinum electrode for the study of fast reactions has been shown by evaluating the specific reaction rates of brominations of m-acetotoluidide, acetanilide and o-acetotoluidide in aqueous solution.

Oxidation of α-ketoglutaric acid with Ce(IV) ions in a solution of sulphuric acid is a reaction of the first order with respect to both Ce(IV) ions and substrate, is acid catalysed, and its rate is proportional to the reciprocal square of the equilibrium HSO4- concentration. From the temperature dependence of the rate constant in 1.5M-H2SO4, the activation parameters were determined as ΔH##f = 57 kJ/mol and ΔS##f = -45 J mol-1 K-1. The redox reaction proper consists apparently of two steps: in the first one, the enol form of α-ketoglutaric acid reacts with Ce(IV) ions with the formation of the corresponding radical; in the second one, the latter is oxidized further with Ce(IV) to give malonic and succinic acids. Conditions are indicated under which α-ketoglutaric acid serves as substrate for the Belousov-Zhabotinskii oscillation reaction in the presence of Ce(IV)-Ce(III) redox catalyst. Oscillations of Ce(IV) and Br2 concentrations, shifted in phase, can be recorded polarographically with a rotating platinum electrode.

The deposition of lithium in dimethylformamide (DMF) has been studied by means of galvanostatic measurements. The overpotential was recorded during constant current pulses of so short a duration that only a few monolayers per pulse were deposited. The experiments were carried out under conditions of minimum contamination of the metal surface. The deposition process of Li in DMF is irreversible, the electron transfer being the rate-determining step. A mechanism of Li electrodeposition in DMF was proposed.
