- 英文摘要: In this study, the solubilities (CS) of BzR3NX, R=Me, Et and Bu; X = Cl, Br and I, in solvents with a dielectric constant (e) range of 1.991~46.68 were measured. In this range of the dielectric constant, the solvent could affect the solubility by up to 105-fold. For BzR3NCl , ln CS increase linearly with increasing e when e < 8.0. Besides the solubility, the limiting equivalent conductance and the thermodynamic association constant (KA) of the above salts and the salts Bu4NX, X = Cl, Br, I and HSO4, in H2O, CH3CN, MeOH, C2H5NO2 and EtOH were also determined using the modified DHO conductance equation. Furthermore, for Bu4NCl, both the temperature effect on and KA and the solvent effect on KA and the partition coefficient (Kp) were investigated. The results showed that the association was exothermic; lnKA increased linearly with increasing 1/e, and lnKp decreased linearly with increasing 1/e.
