Abstract:

The standard transfer Gibbs energy(ΔtrGΘ ) of potassium tetraphenylborate (KBPh4) from water to water and 2-propanol solvent mixtures and from methanol to methanol and 2-propanol solvent mixtures within the whole concentration range of the mixed solvents are studied at 298.15 K. TheΔtrGΘ value of KBPh4 reaches an extreme value from water to water and 2-propanol solvent mixtures, while it increases monotonically with an increasing of 2-propanol content in methanol and 2-propanol solvent mixtures. This indicates the different interaction of KBPh4 with the two kind of solvent mixtures.

Key words: Standard transfer Gibbs energy, Solvent mixtures, Potassium tetraphenylborate
