摘要
The thermodynamic and kinetic behaviours of alkali metal ion transfer facilitated by some crown ethers (18-crown-6, dibenzo-18-crown-6, dibenzo-24-crown-8) from water to nitrobenzene were studied by means of cyclic voltammetry and impedance measurement. The results indicate that each crown ether forms complexes with the respective alkali metal cations, of which stability constants are dependent on the sort of crown ethers and alkali metal cations. Moreover, the potential dependence of the rate constant of the facilitated ion transfer is sensitive to the stability constant in the nitrobenzene phase. © 1990.
