摘　　要：The standard transfer Gibbs energy(Δ trG ) 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.TheΔ trG 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.The standard transfer Gibbs energy(Δ trG ) 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.TheΔ trG 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.
