摘要
测定了四氯化碳分别与N-甲基吡略烷酮环戊酮、吡啶、2-丁酮、1-戊醇、异丙醇、甲基环己烷构成的二元溶液在293.15、298.15K的过量体积和体积过量折射率。提出了一个过量体积和体积过量折射率的关联公式。
The excess volumes and volume excess refractive indexes have been measured over entire composition range at 293.15 and 298.15K for tetrachloromethane+1-methyl-2-,pyrrolidinone, +cyclopentanone, +pyridine, +2-butanone, +1-pentanol, + 2-propanol, or+methylcyclohexane. The results show that V_E for CCl_4+C_5H_9NO, +C_5H_8O, + C_5H_5N are large negative value. It is attributed to a chargetransfer interaction between tetrachloromethane and the second components. The excess volumes for (CCl_4+C_5H_9NO) are the largest negative, its minimum value is-1.19 cm^3 mo1^(-1) at 298.15K, The V^E for CCl_4+(CH_3)_2CHOH, +C_5H_(11)OH are positive or slight negative, suggesting that there is not the specific interaction between tetrachloromethane and alcohol molecules.We propese a semi-empirical formula for predicting excess volume of binary mixtures on volume excess refractive index. The results are satisfactory.
