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

“…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).…”

Excess thermodynamic properties of binary and ternary mixtures containing methyl 1,1-dimethylethyl ether (MTBE), -heptane, and methanol at= 313.15 K

“…For the ternary system, the results of the correlation are given in table 6. In table 7, we have compared Methanol (3) MTBE ( (25,26) which have been reduced using a three-parameter Margules equation. We have also calculated the values of the excess molar entropy S E m for the ternary system using literature data for the excess molar enthalpy H E m at the same temperature of 313.15 K. (27) The resulting values are given in table 8.…”

“…The (26) namely: x 1 azeotrope = 0.7358 and p azeotrope = 66.310 kPa, and x 1 azeotrope = 0.74604, and p azeotrope = 45.434 kPa for {x 1 CH 3 OH + (1 − x 1 )CH 3 (CH 2 ) 5 CH 3 }.…”

Quaternary (liquid+liquid) equilibria for (methanol+2,2,4-trimethylpentane+toluene+1,1-dimethylpropyl methyl ether or 1,1-dimethylethyl methyl ether) at T=298.15K

“…The pure and cross second virial coefficients B were estimated by the method of Hayden and OÕConnell [19]. An optimum set of the binary energy parameters a ji was obtained using equations (4) and (5) by the method of maximum likelihood principle [17], where the standard deviations in the experimental values were taken as 0.133 kPa in pressure, 0.05 K in temperature, 0.001 in liquid-phase mole fraction and 0.003 in vapour-phase mole fraction. The binary energy parameters for the partially miscible mixtures were obtained from the mutual solubility data by solving equations (6) and (7).…”

“…The experimental results are predicted by using an associated-solution model [1] having binary parameters obtained from binary phase equilibria and are reproduced by modified and extended forms of the UNIQUAC models [2,3] including ternary and quaternary parameters obtained from the ternary and quaternary (liquid + liquid) equilibria in addition to binary ones. The binary (vapour + liquid) equilibria, mutual solubility and ternary (liquid + liquid) equilibria relevant to the quaternaries have been available from the literatures: (vapour + liquid) equilibria, (methanol + TAME) [4], (methanol + MTBE) [4], (methanol + toluene) [5], (TAME + MTBE) [6], (TAME + toluene) [7], (MTBE + toluene) [8], 0021 (TMP + toluene) [9], (TAME + TMP) [7] and (MTBE + TMP) [10]; mutual solubilities, (methanol + TMP) [1]; ternary (liquid + liquid) equilibria, (methanol + TA-ME + TMP) [1], (methanol + MTBE + TMP) [1] and (methanol + toluene + TMP) [1].…”
