“…Figures a and b show that the alkanols containing binary mixtures present asymmetrical V E curves, slightly skewed toward alcohol low mole fraction with 1,4-dioxane and sigmoid with 1,2-dichloroethane. It can be seen also, from Table and Figures a and b, that our V E results are well compared with the literature V E data reported for the binary systems 1,4-dioxane + 1-propanol or 2-propanol , and 1-propanol or 2-propanol + 1,2-dichloroethane, , and large discrepancies are observed with other literature reports, for 1,4-dioxane + 2-propanol or 1,2-dichloroethane and 1-propanol + 1,2-dichloroethane binary mixtures. A comparison of our experimental maximum V E values with corresponding literature data, at all working temperatures, for all the binary mixtures, shows similar agreement and discrepancies, as can be seen from Table .…”

Densities, ρ, and molar excess volumes, V E , for binary and ternary systems of (1,4-dioxane, 1-propanol or 2-propanol, and 1,2dichloroethane) were measured over the whole composition range, at T = [288.15, 298.15, 308.15, and 318.15] K, and atmospheric pressure. The density measurements were performed using an Anton Paar vibrating U-tube densimeter. The binary mixtures of 1-propanol or 2-propanol with 1,4-dioxane present positive V E values over the whole composition and working temperature ranges, whereas with 1,2-dichloroethane even negative V E values are observed at higher alcohol mole fraction and at lower temperature. The V E magnitude, for the alkanol containing binary mixtures, increases as the temperature increases and decreases for 1,4-dioxane + 1,2-dichloroethane. The experimental V E data, for all the binary mixtures, were fitted to the Redlich−Kister equation. For all the ternary mixtures, the excess molar volumes are found to be positive and increase with the temperature increase. The experimental ternary V E values were fitted to the Cibulka equation. The capability of the Prigogine−Flory−Patterson theory (PFP model) in predicting excess volume, for binary mixtures, was tested. Comparison of the experimental V E values with the PFP calculations, for all the binary mixtures, at 298.15 K, was graphically presented.

“…The postulation of molecular entities XI–XIV then suggests that there must be a change in (C–O); (C–H) vibrations of THP or D and (CO); (C–H) vibrations of CHO, CHPO on the addition of (1) to (2) in (1 + 2) mixtures. It was observed that THP, D, CHO, and CHPO in their pure state showed characteristic vibrations at 1091, 1083 cm –1 (C–O vibration in THP and D); 2753, 2754 cm –1 (C–H vibrations in THP and D); , 1714, 1694 cm –1 (CO vibrations in CHO and CHPO); 2938, 2948 cm –1 (C–H vibrations of CHO and CHPO) . However, characteristics vibrations for equimolar (1 + 2) mixtures were observed at 1121, 1112; 1123,1122 cm –1 (C–O vibration for THP or D in THP or D (1)+ CHO or CHPO (2) mixtures); 2755, 2757; 2749, 2752 cm –1 (C–H vibrations for THP or D in THP or D (1)+ CHO or CHPO (2) mixtures); 1712,1702; 1701, 1702 cm –1 (CO vibration or CHO or CHPO in THP or D (1) + CHO or CHPO (2) mixtures); and 2922, 2931; 2959, 2928 cm –1 (C–H vibration of CHO or CHPO in THP or D (1)+ CHO or CHPO (2) mixtures).…”

The densities ρ, speeds of sound u, and molar heat capacities C P of tetrahydropyran or 1,4-dioxane (1) + cyclohexanone or cycloheptanone (2) mixtures at 293.15, 298.15, 303.15, and 308.15 K, and excess molar enthalpies, H E at 308.15 K and atmospheric pressure 0.1 MPa have been measured over the entire composition range. The excess molar volumes V E, excess isentropic compressibilities κS E, and excess heat capacities, C P E of the studied mixtures have been determined using the measured experimental data. The observed V E, κS E, H E, and C P E data have been tested in terms of graph theory. The analyses of V E data by graph theory suggest that while tetrahydropyran or 1,4-dioxane exists as a mixture of monomer and dimer; cyclohexanone or cycloheptanone exists as a mixture of open and cyclic dimer. Further, (1 + 2) mixtures are characterized by interactions between oxygen atom/s and hydrogen atom of tetrahydropyran or 1,4-dioxane with hydrogen atom/s and oxygen atom of cyclohexanone or cycloheptanone. The quantum mechanical calculations and analysis of IR spectral data of (1 + 2) mixtures also support this viewpoint. It has been observed that graph theory correctly predicts the V E, κS E, H E, and C p E data of the present mixtures.
