水-DMF-NaCl系统活度系数和粘度测定
Measurement of Activity Coefficient and Viscosity of Water-DMF-NaCl Mixture
摘要
Abstract
Activity coefficients of NaCl in water-N,N-dimethylformamide (DMF) mixed solvents are determined at 298.15K by EMF measurement with sodium ion selective electrode and Ag-AgCl electrode. It is shown that the activity coefficient of NaCl decrease with the increase of concentration of DMF in mixed solvents. The viscosities of water-DMF-NaCl ternary system at different temperature have also been measured. The experimental viscosities have been correlated by using pseudo-binary solute aggregation model presented by Liu et al. The mean deviation between calculated results and experimental data is 2.5%.关键词
