| 摘 要： | 用 SRK、PR 和 YU-LU 三个立方型状态方程对常压下的液体混合过量体积进行了关联计算,涉及的体系包括非极性、弱极性、水及羧酸等强极性混合物。对于对称的非极性、弱极性、极性流体混合物获得了良好的结果,但这种计算方法不适用于含水或羧酸的体系。

| Abstract: | Excess molar volumes of liquid mixtures of non-polar,slightly polar,polar compounds, water and carboxylic acids at atmospheric pressure were correlated by three cubic equations of state: SRK,PR and Yu-Lu equations.Satisfactory results were obtained for symmetric mixtures of non-po- lar,slightly polar and polar compounds,but all equations were poor for systems containing water and earboxylic acids. |

| Keywords: | equation of state excess molar volume correlation |
