Excess molar volumes, speeds of sound, and isentropic compressibilities of binary mixtures of furfural with some aliphatic alcohols

Excess molar volumes and isentropic compressibilities for the binary mixtures of furfural with methanol, ethanol, 1 -propanol, 2-propanol, 1-butanol, and 2-butanol have been computed from the experimentally measured densities and sound speeds at 308.15 K over the entire composition range. All the systems studied exhibit contraction on mixing. The results have been discussed in terms of the specific interactions between the component molecules of the binary mixtures. Keywords: excess molar volumes, isentropic compressibilities, furfural, aliphatic alcohols, unlike reactions.

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.

The excess molar volumes, [Formula: see text], of 2-hexanone (MBK) with n-hexane, n-heptane, n-octane, n-nonane, n-decane, n-undecane, n-dodecane, and n-tridecane have been obtained at 298.15 K from densities measured with a vibrating tube densimeter. The [Formula: see text] are positive over the entire composition range in all mixtures, with the exception of the MBK + n-hexane system, where an inversion of the sign of [Formula: see text] is observed. In other systems, [Formula: see text] increases with increasing size of the alkyl group in n-alkane.
