摘    要:The standard Gibbs energiics of transfer (△rG^0) for potassium tetraphenylborate (KBPh4) have been studied in the system of water and water l-propamol (PrOH) as well as water and water t-butyl alcohol (TBA) at 298.15K. The rcsults show that -△rG^0 cxhibits a complicated changing pattern with the mole fraction of TBA(x (TBA)) or PrOH (x (PrOH)), and △rG^0 has the a maximum value at x (TBA) = 0.2 or x (PrOH) = 0.2. Especially, -△rG^0 of KBPh4 changcs unusually with increasing x (TBA) when x (TBA) <0.05. The reasons for these changes were analyzed and discussed.

Abstract:The standard Gibbs energies of transfer (ΔtrG0) for potassium tetraphenylborate (KBPh4) have been studied in the systems of water and water +1-propanol (PrOH) as well as water and water + t-b utyl alcohol (TBA) at 298.15*$K. The results show that -ΔtrG 0 exhibits a complicated changing pattern with the mole fraction of TBA(x (TBA)) or PrOH (x (PrOH)), and ΔtrG0 has the a m ax imum value at x (TBA) = 0.2 or x (PrOH)=0.2. Especially, -ΔtrG0 of KBPh4 changes unusually with increasing x (TBA) when x (TBA) < 0.05. The reasons for these changes were analyzed and discussed.
