Molar Excess Volumes

The molar excess volumes at 25 °C in nine binary systems of n-hexadecane with 1-n-chloroalkanes from 4 through 18 carbons have been calculated from density measurements. The applicability of Brønsted and Koefoed's congruence principle to the excess volumes was investigated.

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.

Densities at 20 °C and molar excess volumes calculated from them are reported in the work for the mixtures of the substances: propionic acid-n-heptane, propionic acid-benzene, trifluoroacetic acid-benzene, propionic acid-cyclohexane, acetic acid-cyclohexane, acetic acid-trifluoroacetic acid, acetic acid-propionic acid, and propionic acid-trifluoroacetic acid. For the last system mentioned, a strange dependence of excess volume on composition was found which is noted for three local extremes. The dependences of excess volume on composition are correlated by the Redlich-Kister polynomial.

Parameter Theory

The molar excess enthalpies and molar excess volumes of carbon tetra- chloride + hexafluorobenzene have been measured at 298.15 K and 308.15 K. The values for the equimolar mixture at 298 15 K are 490 J mol-1 and 0.875 cm3 mol-1 respectively. The results are compared with the values for other liquid mixtures containing a fluorocarbon as one component, and discussed in terms of solubility parameter theory.

Molar Excess Volumes

The excess volumes VE of the binary mixtures 2-pyrrolidinone–(C6–C10) n-alkanols have been calculated from density measurements over the whole composition range and the 298.15–318.15 K temperature range. The excess volumes were independent of temperature, but changed noticeably with the chain length of the alkanol. The VE values were only positive starting from heptanol, with the maximum value, 0.239 cm3 mol−1, for equimolar decanol. The observed changeover VE < 0 to VE > 0 suggests that the steric effect is primarily responsible for the positive contributions to VE. The thermal expansion coefficients α were evaluated from the variation of densities with temperature. Key words: excess volumes, 2-pyrrolidinone, n-alkanols, liquid mixtures, hydrogen bonding.
