Thermodynamic properties of 2,5,8-trioxanonane + n-octane mixture at 298.15 K

Temperature dependence of the volumetric properties of binary mixtures containing alcohols (1-propanol, 1-pentanol, 1-heptanol) + heptane

“…The compositions of the mixtures were determined by mass. The densities of the pure liquids agree closely with the literature values (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19) as shown in Table 1. The accuracy of the measurements of the mole fractions in this instance was estimated at ±0.000 05, and that of the densities was ±0.000 01 g-cnr3.…”

Glymes as versatile solvents for chemical reactions and processes: from the laboratory to industry

“…Ref 45 (this reference also reported other thermodynamic properties of diglyme at 25 °C such as dipole moment μ = 1.87 D, heat capacity C p = 276.9 J mol −1 K −1 , etc. ),…”

“…Other experimental or theoretic studies of physical properties of glymes or glyme-containing mixtures can be found in literatures: optical anisotropies of monoglyme, diglyme, triglyme and tetraglyme, 82 excess heat capacities of liquid mixtures of triglyme and tetraglyme with cyclohexane as well as tetraglyme with n -heptane at 288.15, 298.15 and 308.15 K and at atmospheric pressure, 83 weak self-association of glymes based on the evaluation of excess isobaric thermal expansion of glyme and alkane mixtures by an associated mixture model with equation of state contribution, 84 excess molar volumes and excess molar isobaric heat capacities of glymes and ethyl acetate, 44 excess molar volumes and viscosities of glyme and acetonitrile, 85 excess thermodynamic and equilibrium properties of glyme + n -alkane mixtures, 45, 65, 66, 71, 81 isobaric vapor-liquid equilibrium for the binary systems of monoglyme + alcohols, 53 excess molar volumes of binary mixtures of glymes and 1-propanol, 59, 60, 63 calorimetric study of interactions between glyme and alcohol, 61 dynamic viscosities of mixtures of refrigerant (HFC-134a) + glyme at different temperatures and pressures, 86 excess molar enthalpies of mixtures of methanol or trifluoroethanol + glyme, 87, 88 static relative permittivities of the ternary system of 2-methoxyethanol + 1,2-dimethoxyethane + water from −10–80 °C, 78 vapor-liquid equilibrium of binary systems consisting of monoglyme with toluene, methylcyclohexane, or (trifluoromethyl)benzene, 69 solubility of HFC-134a refrigerant in glymes, 89 densities, viscosities, and refractive indices of diglyme + cyclohexane or + 1,2,3,4-tetrahydronaphthalene, 70 excess molar heat capacities of mixtures of glymes and various alkanes, 79 and excess heat capacities of glyme-dimethylsiloxane systems at 25 °C, 90 etc. López et al 91 estimated the densities, isothermal compressibilities, and isobaric thermal expansion coefficients of glymes in the temperature range of 293.15K–353.15K at pressures up to 100 MPa from the P-c-T data ( c is the speed of sound in glyme), and found the indirect predictions matched direct experimental values.…”
