用色谱法测定了不同温度下，低碳醇、水在含盐（乙酸钾、硫氰酸钾、硫氰酸钠）1，3-丙二醇中无限稀释活度系数，醇、水的相对挥发度及含盐溶剂的选择度。
The activity coefficients of dilute alcohol and water in 1,3-propanediol containing salts (potassium acetate, potassium thiocyanate and sodium thiocyanate) were determined by chromatography. The relative volatility of alcohol and water And salt solvent selectivity.
