Molar Excess Volumes

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.

Molar Volumes

Excess molar volumes VEm at 298.15 K and atmospheric pressure were calculated over the entire composition range from densities measured with a vibrating-tube digital densimeter for the binary mixtures butyl acetate + methanol, + ethanol, + propan-1-ol, + butan-1-ol, + pentan-1- ol, + hexan-1-ol, + heptan-1-ol, + octan-1-ol, + nonan-1-ol and + decan-1-ol. The excess volumes are positive over the entire composition range for these mixtures except the system butyl acetate + methanol, for which all VEm values are negative. The excess volumes show a consistent trend towards more positive values as the length of the hydrocarbon chain of the alkanol increases. The results suggest the presence of specific interactions.

Theoretical Results

Excess molar volumes υE at 298.15 and 308.15 K and normal atmospheric pressure for the binary mixtures 2-pentanone + 1-chloroalkane (from 1-chlorobutane to 1-chlorooctane) were obtained from measurements of the density with an Anton Paar densimeter. The υE values for all mixtures were positive, and increase as the 1-chloroalkane length increases. Excess molar volumes depend slightly on the temperature. The same characteristics were found previously for the excess molar enthalpies of the same mixtures. Experimental υE values are compared with theoretical results using the Prigogine–Flory–Patterson model. Keywords: thermodynamics, liquid mixtures, excess volumes, ketones, chloroalkanes.

Excess Volumes

Excess volumes of mixtures of 1-propanol +, 1-butanol +, 1-pentanol +, and 1-hexanol + diethylketone have been measured at 303.15 and 313.15 K. Of the four mixtures included here 1-propanol + diethylketone shows an inversion in sign in VE at 313.15 K. VE becomes more positive with increase in temperature.
