| 摘 要： | 在298.15 K下,用振动管密度计在全浓度范围内测量了氯仿、硝基苯分别与均三甲苯、偏三甲苯构成的二元液体混合物的过量摩尔体积VE.其中氯仿与均、偏三甲苯的VE为正值,且均三甲苯＞偏三甲苯;硝基苯与均、偏三甲苯的VE为负值,且偏三甲苯＞均三甲苯.

| Abstract: | The excess molar volumes V~E of {trichloromethane 1,3,5_trimethylbenzene,trichloromethane 1,2,4_trimethylbenzene,nitrobenzene 1,3,5_trimethylbenzene,nitrobenzene 1,2,4_trimethylbenzene} were determined in the whole range of composition using a vibrating_tube densimeter at 298\^15 K.Excess molar volumes V~E are positive for mixtures of trichloromethane with trimethylbenzene. The V~E values at equimolar concentrations of trichloromethane follow the order 1,3,5_trimethylbenzene > 1,2,4_trimethylbenzene.The V~E values of {nitrobenzene trimethylbenzene} are negative.The V~E values at equimolar concentrations of nitrobenzene follow the order 1,2,4_trimethylbenzene > 1,3,5_trimethylbenzene. |
