Excess properties of binary mixtures of an alkanol or an alkane with butyl-vinyl ether oriso-butyl-vinyl ether

Volumetric and viscometric properties of binary mixtures of {methyl tert-butyl ether (MTBE)+alcohol} at several temperatures and p=0.1MPa: Experimental results and application of the ERAS model

“…Several sets of cross parameters can be obtained, which can be related to the selection ranges for these parameters. The values of the adjusted parameters show consistency with values presented by other studies for mixtures containing ethers and alcohols [13,14,16,17,22,23,64,37,74,75]. However, our values for the parameters differ from those found in the literature because the ERAS model equations are not symmetric.…”

“…Negative values of V E m may be attributed to strong specific or chemical interactions between the components present in the mixtures or to structural contributions arising from the geometrical fitting of one component into the other due to differences in the molar volumes and free volume between unlike molecules or may be due to the both. Negative values of excess molar volume for systems containing ethers and alcohols have been associated with hydrogen bonding and complex formation between ether (non-self-associating component) and alcohol (strong self-associating component) and structural effects [12,17,[22][23][24][25]. The possible chemical interactions become weaker with increasing alkyl chain length alcohol.…”

“…Thermodynamic and physicochemical properties of binary liquid mixtures of ethers with alcohols have been studied by Farkova et al [9] (methanol + butyl methyl ether, or +tert butyl methyl ether, or +ethyl propyl ether, or +diisopropyl ether, or +bu-tyl ethyl ether), Toghiani et al [10] (methanol + methyl tert-butyl ether, or +tert-amyl methyl ether), Coto et al [11] (methanol + methyl tert-butyl ether, or +tert-amyl methyl ether), Canosa et al [12] (diethyl ether + methanol, or +ethanol), Kammerer et al [13] (ethanol + ethyl tert-butyl ether), Rezanova et al [14] (diisopropyl ether, or dibutyl ether + methanol, or +ethanol, or +2-propanol, or +1-butanol, or +2-butanol), Gonzalez et al [15] (methyl tert-butyl ether, or tert-amyl methyl ether, or ethyl tertbutyl ether + methanol, or +ethanol, or +1-propanol, or +2-propanol or +1-butanol), Rezanova et al [16] (tert-amyl methyl ether + ethanol, or +1-propanol, or +2-propanol, or +1-butanol, or +2-butanol, or +1-octanol), Rezanova and Lichtenthaler [17] (butyl-vinyl ether, or iso-butyl-vinyl ether + ethanol, or +1-butanol, or +iso-butanol), Segade et al [18] (methyl tert-butyl ether + 1-propanol), Piñeiro [19] (diisopropyl ether + alcohol from methanol to 1-undecanol), Aznarez et al [20] (tetraethylene glycol dimethyl ether + 2-propanol, or +2-butanol, or +2-pentanol), and Gómez-Marigliano et al [21] (methyl tert-butyl ether, or tert-amyl methyl ether, or diisopropyl ether + 1-propanol).…”

Densities, Viscosities and Excess Properties of Binary Mixtures of 2-Methoxy-2-methylpropane with iso-Propanol

“…We can notice that the excess molar volumes are negative in the whole composition range and at all temperatures. Negative values of excess molar volume were associated with hydrogen bonding and complex formation between ether (non-self-associating component) and alcohol (strong self-associating component) as well as with structural effects [22][23][24][25][26]. The effect of temperature on the V E shows a systematic decrease with temperature for all the mixtures.…”

Thermodynamic Excess Properties for Ternary Mixtures 1-Butanol + (Butyl Vinyl Ether or Isobutyl Vinyl Ether) + Heptane

“…The thermodynamics of mixtures containing ethers have been extensively investigated, as recently reviewed by Marsh et al Experimental H E values of binary and ternary mixtures containing major members of the ether oxygenate family [methyl tert -butyl ether (MTBE), , ethyl tert -butyl ether (ETBE), or tert -amyl methyl ether (TAME) 6-8 ] as well as experimental V E and excess heat capacities of binary, ternary, and quaternary mixtures containing ETBE 9,10 have been published. Kammerer and Lichtenthaler 11 and Rezanova et al , have published experimental results of H E and V E for binary and ternary mixtures of alkanol + ether (DIPE or DBE) + alkane (heptane) at 298.15 K. In another paper excess thermodynamic properties of binary alkanol or alkane + ether (butyl vinyl ether or isobutyl vinyl ether) have been reported …”
