Measurements and analysis of excess volumes of some alkan-2-one-1-chloroalkane mixtures using Nitta–Chao and Prigogine–Flory–Patterson models

Abstract

Excess molar volumes vE at 298.15 and 308.15 K and normal atmospheric pressure for the binary mixtures butan-2-one-1-chloroalkane (from 1-chlorobutane to 1-chlorooctane) have been determined from density measurements using a vibrating tube densimeter. The vE values for all the mixtures are positive, increase as the 1-chloroalkane length increases, and are slightly dependent on the temperature. Experimental vE data are compared with theoretical predictions using the Prigogine–Flory–Patterson model with interaction parameters calculated from excess molar enthalpies measured previously in the same mixtures. These vE values, together with literature data on excess molar enthalpies and vapour–liquid equilibria, are then used to determine the interaction energies between chloro and ketone groups on the basis of the Nitta–Chao group-contribution model. These parameters may be used to predict thermodynamical properties of binary or ternary mixtures containing ketones and chloroalkanes.
