Abstract: The standard transfer Gibbs energies (ΔtrG°)of KBPh4 from reference solvent of water to water/ethanol, water/propanol, water/2 propanol,water/ethylene glycol, water/glycerol mixtures in different proportional ratio have been studied. The interactions of KBPh4 with the above mixed solvents were analyzed. The standard transfer Gibbs energy of cavity(ΔtrG°cav) and the standard transfer Gibbs energy of interaction(ΔtrG° int) from water to water/2propanol mixtu res at 298.15 K were calculated by the Scaled Particle Theory (SPT).

Key words: Standard transfer Gibbs energy, Standard transfer Gibbs energy of cavity, Standard transfer Gibbs energy of interaction, Potassium Tetrophenylborate
