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).…”

Heat capacities of the mixtures of ionic liquids with methanol at temperatures from 283.15K to 323.15K

“…The positive values of C E p of the binary mixtures containing alcohols and proton acceptors (ethers), were explained previously [17,18] as a result of two competing processes: alcohol self-association and heteromolecular association through hydrogen bonds. It was also proved that the heteromolecular association process gives a negative contribution to C E p , which decreases the maximum of C E p .…”

“…This may be a result of the breaking up of hydrogen bonds in the mixture. Generally, the specific interactions in the mixture, typically H-bonds, break up as the temperature increases, while the dependence on temperature of the non-specific interactions is lighter and can usually be neglected [17].…”

Liquid densities, heat capacities, refractive index and excess quantities for {protic ionic liquids+water} binary system

“…The dependence of the excess isobaric heat capacity on the mixture reflects indirectly the interactions between molecules in solution [31,32]. In binary mixtures containing a protic dipolar solvent such as water, a proton donor like the pyrrolidinium cation and a proton acceptor like the nitrate anion, a competition occurs between two processes -the self-association of water or PIL molecules and the new heteromolecular associations through hydrogen bonds in the mixture.…”
