Solubilities (S) of KBPh4 in water, methanol, ethanol, 1-propanol, 1-butanol, 1-pentanol, 1-hexanol, 1-octanol at 288.15, 298.15, 308.15, 318.15, 328.15K have been determined by the spectrophotometry. These data can be expressed by 1gS=-(1.4184-0.8725lgn)/(1-132.45T-1), where n are the atomic number of carbon for the straight chains monohydric alcohols; T is the temperature. The standard transfer free energies (△tG) of KBPh4 from water to straight chains monohydric alcohols in the temperature ranges of 288.15-328.15K have been calculated. The results can be expressed as △tG=-18.029+5.766×10-5T2+(6.817×10-2-5.302×10-10T3)-1lgn.
