Thermodynamic excess properties and vapor–liquid equilibria of binary and ternary mixtures containing methanol, tert-amyl methyl ether and an alkane

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.…”

Excess molar volumes and excess molar enthalpies of binary and ternary mixtures of 1-butanol, a tertiary amine (tri-n-butylamine or tri-n-octylamine) and n-hexane: Experimental results and ERAS-model calculations

“…It is rather successful in describing, V E m ; H E m ; C E p;m and G E m simultaneously for binary [2,3] as well as for multi-component systems [26][27][28]. In those papers, the relevant model equations are given.…”

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

“…In previous papers, experimental H E m of binary and ternary mixtures containing major members of the ether oxygenate family proposed as octane number enhancers have been published: MTBE (methyl tert-butyl ether), (1,2) ETBE (ethyl tert-butyl ether), (3) or TAME (tert-amyl methyl ether), (4)(5)(6) as well as experimental V E m and excess heat capacities C E p,m of binary, ternary, and quaternary mixtures containing ETBE. (7,8) Although MTBE is currently produced on a large scale, interest in other ethers as efficient substitutes continues to increase steadily and, correspondingly, the interest in thermodynamic properties of mixtures with ethers.…”
