Excess Volumes of (2-Ethoxyethanol + Alcohols) at 308.15 K

Excess Molar Volumes and Viscosities for Binary Mixtures of 2-Propoxyethanol and of 2-Isopropoxyethanol with 2-Pyrrolidinone, N-Methyl-2-pyrrolidinone, N,N-Dimethylformamide, and N,N-Dimethylacetamide at 298.15 K

“…This is a part of our ongoing program of research on the thermodynamic, acoustic and transport properties of binary mixtures containing straight-chain or branched-chain alkoxyethanols as one of the components. − In continuation of our earlier investigations, we report here the new experimental data of the excess molar volumes and viscosities η of binary solvent mixtures containing 2-propoxyethanol or 2-isopropoxyethanol with 2-pyrrolidinone, N -methyl-2-pyrrolidinone, N , N -dimethylformamide, and N , N -dimethylacetamide over the whole composition range at 298.15 K and atmospheric pressure. The thermodynamic properties of mixtures of straight-chain or branched-chain alkoxyethanols with either alkanol , or water , have been studied. A few other studies involving the viscosities, excess molar volumes, and speeds of sound of N , N -disubstituted amides + alkanol − and + water and other thermodynamic and spectroscopic properties of cyclic amide + water , and + alcohol 13 have also been performed.…”

Thermodynamic, Ultrasonic, and Transport Study of Binary Mixtures Containing 2-(2-Methoxyethoxy)ethanol and Alcohols at (293.15–323.15) K

“…As already mentioned below, the V m E values are negative over the complete composition range in the case of methanol, ethanol, and propan-1-ol systems and positive for the butan-1-ol and butan-2-ol systems. These results may be explained by the depolymerization of self-associated alkoxyalkanols by the alcohols and self-associated alcohols by the alkoxyalkanols, which contribute to the expansion of volume and the hydrogen bond formation between alkoxyalkanols and alcohols leading to volume contraction . According to the V m E results, we can suggest that expansion of volume is dominant in butan-1-ol and butan-2-ol systems, while the contraction in volume is dominant in methanol, ethanol, and propan-1-ol systems.…”

“…According to the V m E results, we can suggest that expansion of volume is dominant in butan-1-ol and butan-2-ol systems, while the contraction in volume is dominant in methanol, ethanol, and propan-1-ol systems. The positive deviations are mostly because of H-bond breaking, while negative could be because of weak specific interactions between unlike molecules . The V m E values decrease with an increase of temperature for (22MEE + methanol, or +ethanol, or +propan-2-ol, or +butan-2-ol) binary mixtures may be because of a decrease of packing efficiency between 22MEE and methanol, or +ethanol, or +propan-2-ol, or +butan-2-ol, and vice versa for (22MEE + propan-1-ol, or+ butan-1-ol) binary mixtures where increases.…”

Measurements and Modeling of Physicochemical Properties of Pure and Binary Mixtures Containing 1,2-Dimethoxyethane and Some Alcohols

“…According to the V m E results, we can suggest that the contraction in the volume is dominant over the entire composition range in mixtures of 1,2-DME with methanol or propan-1-ol, while for mixtures of 1,2-DME with propan-2-ol and butan-2-ol, the expansion of the volume is dominant. The positive deviations are mostly due to H-bond breaking, while negative ones could be due to weak specific interactions between unlike molecules …”
