Thermodynamics of binary mixtures containing organic carbonates. 1. Excess enthalpies of dimethyl carbonate + hydrocarbons or + tetrachloromethane

Temperature dependence of the excess molar volume of (dimethyl carbonate, or diethyl carbonate+ toluene) fromT= 278.15 K to 323.15 K

“…However, for (diethyl carbonate + toluene) the excess molar volumes are negative, but small. García de la Fuente et al (13)(14)(15) have found a similar behaviour for the excess enthalpies. For dimethyl carbonate H E m is positive and for diethyl carbonate the H E m (x) curve presents an s-shape form.…”

“…Up to now, we have found in the literature (vapour + liquid) equilibrium data, (9)(10)(11)(12) excess molar enthalpies (13)(14)(15) at T = 298.15 K, and excess molar volumes (12,16,17) at T = 298.15 K for (di-n-alkyl carbonate + benzene) as well as activity coefficients at infinite dilution (18) at T = 318 K, excess molar enthalpies (13)(14)(15) and excess molar volumes (16,17) at T = 298.15 K for (di-n-alkyl carbonate + toluene).…”

“…For this reason, we report in this paper excess molar volumes of (dimethyl carbonate + toluene) at the temperatures (278. 15 In addition, using the excess molar volumes at different temperatures, the cubic expansion coefficients α, excess cubic expansion coefficients α E , and values of (∂ V E m /∂ T ) p and (∂ H E m /∂ p) T were calculated.…”

Excess properties of the binary mixtures of methylcyclohexane+alkanes (C6 to C12) at T=298.15K to T=308.15K

“…Aminabhavi and co-workers [1][2][3][4][5][6] have studied molecular interactions and thermodynamic properties of several binary mixtures of different types of liquids as first components with n-alkanes as the second component. Binary mixtures containing different alkanes with a variety of organic liquids, have been extensively studied by different authors [7][8][9][10][11][12][13][14], with respect to different properties. Different excess properties of binary mixtures containing methylcyclohexane as one of the components with a variety of liquids have also been studied by a large number of researchers [15][16][17][18][19][20][21][22].…”

Permittivity and density of binary systems of {dimethyl or diethyl carbonate}+n-dodecane from K

“…Over the last several years, many studies have been carried out on the thermophysical properties of mixtures containing carbonates + n-alkanes [1][2][3][4][5][6][7][8][9]. The study of such systems is important because of the presence of large and complicated carbonate groups which make them interesting for the verification of the applicability of group contribution models [6].…”
