Excess enthalpies and excess volumes of binary mixtures containing tetrahydrofuran

Study of Weak Molecular Interactions through Thermodynamic Mixing Properties

“…Our V E results for the mixtures tetrahydrofuran or tetrahydropyran with benzene are in excellent agreement with those of Meyer 7 and Andrews, 3 respectively. Excess molar volumes and excess isentropic compressibilities are graphically represented in Figures 1 and 2, respectively.…”

“…In this work, a comprehensive thermodynamic study of mixtures formed by a cyclic ether (tetrahydropyran or tetrahydrofuran) and an aromatic compound (benzene, fluorobenzene, or chlorobenzene) has been performed. These kinds of mixtures have attracted the attention of some scientists before, ,,− although these studies were focused mainly on the interpretation of volumetric or calorimetric measurements of mixtures involving tetrahydrofuran or tetrahydropyran with benzene…”

“…In this work, a comprehensive thermodynamic study of mixtures formed by a cyclic ether (tetrahydropyran or tetrahydrofuran) and an aromatic compound (benzene, fluorobenzene, or chlorobenzene) has been performed. These kinds of mixtures have attracted the attention of some scientists before, 3,4,[6][7][8][9][10][11][12] although these studies were focused mainly on the interpretation of volumetric or calorimetric measurements of mixtures involving tetrahydrofuran or tetrahydropyran with benzene An entire study requires the complete knowledge of a set of properties of the studied mixtures involving both bulk and surface properties, and it is only then when a minute description of the processes occurred during the mixture can be picked up. The methodology for the thermodynamic characterization is based on measurements of density, speed of sound, refractive index, surface tension, heat of mixing, and vapor-liquid equilibrium together with the derivation of the corresponding excess or deviation properties.…”

Excess volumes of binary mixtures of tetrahydrofuran with various hydrocarbons at 313.15 K

“…Their Y E values for the two sets of binary mixtures are consistently higher over the entire composition range than the ones reported by us. A similar observation was made by us for tetrahydrofuran solutions containing benzene (4).Excess volumes for tetrahydrofuran + cyclohexane mixtures reported by Geier and Bittrich (9) at 298.15K show poor agreement with the other available literature values(10)(11)(12) whereas their data at 303.15 K show areasonably good agreement with the report of Deshpande and Oswal(13). To the best of our knowledge, no YE data have been reported in the literature for the other binary mixtures considered in this paper.It is established that the sign and magnitude of YEgive a good estimate of the strength of the unlikeFIG.…”
