摘要:
Using dipole moment measurements, the Gibbs energy DeltaG(PT) Of proton transfer in the complex of 2,6-dichlorophenol with triethylamine was determined in different solvents. The effect of solvent on DeltaG(PT) was quantitatively discussed in terms of reaction field models for homogeneous and heterogeneous dielectric media. The specific complex-solvent interactions which, in addition to electrostatic interaction, stabilize the PT polar form of the complex is discussed as a function of the empirical parameters describing the polar and hydrogen-donating (electron-accepting) properties of the solvent.
