| Abstract: | In this paper, the solubilities of NH4Bph4 in diferent compositions (CH3OH-H2O) mixtures at 298. 15K were determined by photometric method, and obtained the activity coefficients, associate degrees,activity product constants of ions of NH4Bph4 in the mixtures and the standard Gibbs free energies of transfer of NH4Bph4 from the pure water to six compositions mixtures at 298.15K from thermodynamical principles. The changes of thermodynamical propertie constants of NH4Bph4 with contents of organic cmposition (xs) in the mixtures were discussed from theories of association and solvation of ions for eletrolytic solution. |
