| 摘 要： | 在 2 98 15K和 30 8 15K下用振动管密度计在全浓度范围内测量了桉叶油素分别与四氯化碳和三氯甲烷构成的二元系的过量摩尔体积 .这 2个二元系的过量摩尔体积均为负值 ,且桉叶油素与氯仿的过量体积显著大于桉叶油素与四氯化碳的过量体积 .

| Abstract: | The excess molar volumes of {1,8-cineole CCl 4, CHCl 3} were determined as a function of mole fraction x using a vibrating-tube densimeter at the temperatures 298 15 and 308 15K All mixtures exhibit negative values over the entire composition range at both temperatures.The plots of excess molar volumes against composition show that of 1,8-cineole and chloroform is far lower than that of 1,8-cineole and tetrachloromethane for the same values of x. |
