【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.更多还原
