研究Li_2SO_4-EtOH-H_2O体系25℃气液平衡及液相的粘度和密度。湿渣法确定平衡固相在整个浓度范围内均为Li_2SO_4·H_2O。用经验公式ln(y/y_0)=K_1x+K_2x~2+K_2x~3对体系的溶解度和密度数据进行关联。硫酸锂加入到液相后由于盐离子静电作用对乙醇-水体系粘度的影响。按Jaques的假二元体系模型,用WILSON,NRTL方程关联气液平衡数据。
The gas-liquid equilibrium and liquid viscosity and density of Li_2SO_4-EtOH-H_2O system at 25 ℃ were studied. Wet slag method to determine the equilibrium solid phase in the entire concentration range are Li_2SO_4 · H_2O. The empirical formula ln (y / y_0) = K_1x + K_2x ~ 2 + K_2x ~ 3 was used to correlate the solubility and density data of the system. Effect of Salt Ion Electrostatic on the Viscosity of Ethanol - Water System after Lithium Sulfate Added to Liquid Phase. According to Jaques’s pseudo-binary system model, WILSON and NRTL equations are used to correlate gas-liquid equilibrium data.
