| 摘 要： | 在298.15 K时用振动管密度计在全浓度范围内测量了邻、间、对二甲苯分别与八甲基环四硅氧烷(D4)组成的3个二元液体混合物的密度,并计算了此3个二元体系的过量摩尔体积VE.3个二元体系的VE均为负值,大小顺序为:间二甲苯＞对二甲苯＞邻二甲苯.

| Abstract: | Densities for binary mixtures of octamethylcyclotetrasiloxane with o-xylene, m-xylene,p-xylene respectively were determined at 298.15 K, and their excess molar volumes were derived. It was showed that the excess molar volumes V~E are negative for these three binary systems, and the V~E values are in the order of m-xylene>p-xylene>o-xylene. |

| Keywords: | excess molar volume xylene octamethylcyclotetrasiloxane |
