The standard electron-transfer heterogeneous rate constant of lithium, potassium, sodium and caesium amalgams in N,N-dimethylformamide was ascertained employing cyclic voltammetry in an effort to relate the presence of a non-equilibrium electrode reaction at the dropping lithium amalgam electrode to the variation of the lithium amalgam electrode potential with amalgam electrode con- figuration, i.e. whether streaming, dropping or stationary. Such variations are not observed at other alkali metal amalgam electrodes. ��� In the dipolar aprotic solvents the standard electron-transfer heterogeneous rate constant for the Li(Hg) electrode increases as the solvating power for Li+ decreases, i.e. dimethyl sulphoxide < di- methylformamide < propylene carbonate. Water is a much stronger solvator of Li+ than is propylene carbonate, but the electron transfer is faster in water than in propylene carbonate; the important role of entropic contributions in ion solvation is discussed as an explanation.

Chemiluminescence (CL) of selected inorganic reaction systems, generating ultraweak photon emission, has been studied. The kinetics of the systems and their emission spectra have been characterised by measurements with the use of the stationary and the flow methods of CL recording. The systems studied contained cations at different oxidation degree such asFe2+\3+,Cu+\2+,Co2+\3+,Eu2+\3+,CLO−anions and hydrogen peroxide without organic sensitisers. On the basis of the analysis of the spectra, in particular systems emitters have been identified and mechanisms of the reactions have been proposed. The effect of carbonate and azide ions and propylene carbonate on the yield of CL and spectral characterisation of the systems studied has been evidenced and discussed. A possibility of the application of the systemsEu3+\N3−\H2O2andCo2+\propylene carbonate\H2O2for analytical purposes has been considered.

Rates of formation and destruction of the alkoxyphosphonium ion, the intermediate in the Michaelis–Arbuzov reactions of some methyl esters of trivalent phosphorus acids with methyl iodide, are followed by a conductivity method in the solvent propylene carbonate. Specific conductances of the unstable intermediates are well estimated through stable model salts. Rate constants for both the alkylation of the reagent and the dealkylation of the intermediate are obtained. The conductivity time curves are simulated by adjusting rate constants for two sequential second order reactions, assuming no ion pairing at the concentrations used. In these measurements of the intermediate only, there is no rate-determining step; for the overall reaction the first step is in most cases rate-determining.
