| 摘 要： | 用自制的连续冲稀膨胀计,在298.15K,测定了乙醇-环己烷、环己烷-正庚烷、乙醇-正庚烷三对二元系和相应三元系的过量体积。其中二元系的实验值与文献值良好一致。另外,又利用局部组成模型进行关联,当使用三对二元系的非随机参数,对上述三元系的过量体积进行预测时,预测值与实验值基本相符。

| Abstract: | The excess volumes of ethyl alcohol-cyclohexane, cyclohexane-n-heptane and n-heptane-ethyl alcohol binaries and the corresponding ternary have been measured at 298.15 K by using a continuous dilution dilatometer made in our laboratory. The experhnental data of the three binaries are in good agreement with those reported in the literatures. A local composition model is used to correlate the experimantal data. With the three pairs of nonrandom parameters of those binaries, the predicted excess volumes of the corresponding ternary are consistent with the experimental results. |
