| 摘 要： | 常压下利用U形振动管密度计和乌氏黏度计测定了间二甲苯与醋酸混合液在298.15～343.15K温度下的密度黏度,计算了不同温度组成下的超额体积V^E及混合黏度的变化,对不同温度下超额体积和混合黏度变化与组成的关系分别用Redlichkister方程进行关联,混合黏度与温度的关系用Andrade公式进行关联.

| Abstract: | Densities and viscosities of the binary mixture of m-xylene and acetic acid were determined between 298.15～343.15 K under atmospheric pressure by using a vibrating U - shaped sample tube densimeter and ubbelohde suspended - level viscometer.Density values were used in the determination of excess molar volume.Viscosities were used to calculate the deviations of viscosity.Excess molar volume and deviation of viscosity were fitted by the Redlich - kister Equation.Viscosities were done by the Andrade equation. |
