摘要: <正>对含盐二元系汽液平衡的研究国内外曾不少,其研究手段也各异.在等温汽液平衡实验中,压力是唯一可观测的物理量.若能找出压力与盐量间的关系并揭示其与Furter方程的联系将是很有意义的.本文将依据实验建立这种联系,从而给出在等温情况下盐对二元系压力影响的一般规律.

Abstract: Isothermal vapor-liquid equilibrium data of isopropanol-water NH4Cl, LiCl, CaCl2 and acetone- water-NaI were measured with the improved Rose still. A linear relationship between the total pressure and salts mole fraction at a fixed binary composition was obtained. The equation of linear relationship was derived theoretically and the experimental data were correlated with Margules equation.
