V-E of Binary-Mixtures Containing 5-Pentanone or 3-Heptanone with 1-Chloroalkanes at 298.15 K
The excess volumes, V-E, of the binary mixtures formed by a and alkanone (3-pentanone, 3-heptanone) and a 1-chloroalkane (from 1-chlorobutane to 1-chlorooctane) were determined from densities measured using a vibrating-tube densimeter at 298.15 K. All the systems studied exhibit positive excess volumes over the whole range of concentrations except for the 3-heptanone + 1-chlorobutane for which all the experimental VE values are negative. The excess molar volumes increase as the 1-chloroalkane chain increases and as the 3-ketone chain decreases. This behavior is similar to that found previously for excess molar enthalpies for 2-ketone + 1-chloroalkane mixtures.
