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

• The ρijkρijk and uijkuijk data have been measured at T = (298.15, 303.15 and 308.15) K.
• The VijkE and (κSE)ijk data have been computed from experimental data.
• The excess thermodynamic properties have been fitted to Redlich–Kister equation.
• The experimental data have been analyzed in terms of Graph and PFP theories.

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, VijkE, VEVE and excess isentropic compressibilities, (κSE)ijk, κSE 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, VijkE and (κSE)ijk have been tested in terms of (i) Graph; and (ii) Prigogine–Flory–Patterson (PFP) theories.
