Excess molar volumes and excess isentropic compressibilities of binary and ternary mixtures of o-chlorotoluene with cyclic ether and amides or cyclohexane at different temperatures
Densities and speeds of sound data for ternary o-chlorotoluene (i) + tetrahydropyran (j) + N-methylformamide or N,N-dimethylformamide or cyclohexane (k) and their sub-binary o-chlorotoluene or (tetrahydropyran + cyclohexane) mixtures have been measured at temperatures (298.15, 303.15, 308.15) K and 0.1 MPa. The excess molar volumes, V-ijk(E), V-E and excess isentropic compressibilities, (kappa(E)(S))(ijk), kappa(E)(S) for ternary and binary mixtures respectively have been determined from the experimental densities, speeds of sound values and fitted to Redlich-Kister equation to calculate ternary and binary adjustable parameters along with standard deviations. The excess properties, V-ijk(E) and (kappa(E)(S))(ijk) have been tested in terms of (i) Graph; and (ii) Prigogine-Flory-Patterson (PFP) theories. (C) 2014 Elsevier Ltd. All rights reserved.
