This article reports measurements of VE/m at 298.15 K for binary mixtures of n- alkanols CnH2n+1OH (from n = 2 to n = 10) with ethyl and propyl acetates. All the excess volumes are positive over the entire concentration range, with VE/m increasing with the length of the alkanol chain. Suitable equations have been fitted to the data for each mixture. The results are compared with data previously published.

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.

Theory Of Mixtures

Excess molar volumes, measured at 298.15 K in a tilting dilution dilatometer, are reported for the five binary systems formed by mixing n-octane with n-hexane, 2-methylpentane, 3-methylpentane, 2,2-dimethylbutane, and 2,3-dimethylbutane. The Flory theory of mixtures provides a reasonable correlation of the results in combination with excess molar enthalpies measured previously.

Molar Excess Volumes

Densities and viscosities were determined for the 2-propanol + methylacetate + dichloromethane system at 298.15 K. From the experimental results, molar excess volumes and excess viscosities were calculated. Different expressions exist in the literature to predict these excess properties from the binary mixtures. The empirical correlation of Tsao–Smith and Toop is the best for this system.
