Molar Excess Volumes

Molar excess volumes, VE at 298.15 and 308.15 K, molar excess enthalpies HE at 308.15 K, and total vapour pressure at 298.15 and 308.15 K. have been measured for binary mixtures of 1,2-dichloroethane with aromatic hydrocarbons. The VE and HE data for an equimolar mixture at 308.15 K only have been utilized to predict VE, HE, and TSE values (using Sanchez and Lacombe theory) for these mixtures as a function of temperature and composition. The agreement between the predicted and the corresponding experimental values is good so far as VE and HE data are concerned but the same is not true of the TSE values.

Consistent Trend

Excess volumes have been measured at 293.2 K for n- hexadecane+cyclopentane, +methylcyclopentane, +cyclohexane, +methylcyclohexane, +trans-1,4-dimethylcyclohexane, and +2-methyl- butane, and at 298.2 K for n-hexadecane+2,2,4-trimethylpentane. The corresponding excess enthalpies have been measured at 298.2 and 308.2 K for n-hexadecane+cyclopentane, +methylcyclopentane, +cyclohexane, +methylcyclohexane, and + 1,4-dimethylcyclohexane. Excess volumes have been measured at 298.2 K for all ten binary mixtures of cyclohexane, methylcyclopentane, n-hexane, 3-methylpentane, and 2-methylpentane; the systems cyclohexane+methylcyclopentane and n-hexane +methylcyclopentane show double minima in the curve of VE against x and have been measured at two lower temperatures as well. The excess volumes show a consistent trend towards more negative values as the number of methyl groups increases; the excess enthalpies are more difficult to interpret.
