Abstract

Abstract: The pre-saturation technique is used to extend the validity of the gas stripping method to the determination of infinite dilution activity coefficients in multicomponent solvent systems. A ternary mixture of methanol-acetone-benzene was studied at 298.15K with this method. The values measured were well correlated by the UNIQUAC equation.

摘要： 运用加连预饱和釜技术将气提法适用范围扩展到多组分混合溶剂体系的无限稀释活度系数的测定.据此获得了298.15K温度条件下甲醇—丙酮—苯三元体系各组分的Y~∞i(j,k)值,用UNIQUAC方程关联,结果良好.
