Excess Molar Volumes and Viscosities of 1-Propanol + Ethylene Glycol, + Ethylene Glycol Monomethyl, + Ethylene Glycol Dimethyl, + Diethylene Glycol Dimethyl, + Triethylene Glycol Dimethyl, + Diethylene Glycol Diethyl, and + Diethylene Glycol Dibutyl Ethers at 298.15 K

Abstract

Excess molar volumes and viscosities η have been measured as a function of composition for binary liquid mixtures of 1-propanol, C3H7OH, with ethylene glycol (1,2-ethanediol), HOC2H4OH, ethylene glycol monomethyl ether (2-methoxyethanol), CH3OC2H4OH, diethylene glycol dimethyl ether (bis(2-methoxyethyl) ether), CH3(OC2H4)2OCH3, triethylene glycol dimethyl ether (1,2-bis(2-methoxyethoxy)ethane), CH3(OC2H4)3OCH3, and diethylene glycol diethyl ether (bis(2-ethoxyethyl) ether), C2H5(OC2H4)2OC2H5, at 298.15 K. Viscosity measurements have also been made for the mixtures 1-propanol + ethylene glycol dimethyl ether (1,2-dimethoxyethane), CH3OC2H4OCH3, and + diethylene glycol dibutyl ether (bis(2-butoxyethyl) ether), C4H9(OC2H4)2OC4H9, at 298.15 K over the whole composition range. All the systems exhibit negative deviation from a mole fraction average in viscosity. The excess volumes for all mixtures are negative with the exception of 1-propanol + ethylene glycol monomethyl ether.

Vapor–Liquid Equilibrium, Volumetric, and Compressibility Properties of 1-Propanol + Poly(ethylene glycol) Dimethyl Ether 250 and 500 Binary Mixtures

“…Therefore, the packing effect for the negative values of the obtained V E is creditable for alcohol + polymer systems. For the excess molar volume in the 1-propanol + ethylene glycol, + ethylene glycol monomethyl, + ethylene glycol dimethyl, + diethylene glycol dimethyl, + triethylene glycol dimethyl, + diethylene glycol diethyl, and + diethylene glycol dibutyl ethers systems the negative values are reported at 298.15 K . This behavior of discrepancy of V E values with temperature is similar to the studied systems in this study.…”

Microscopic Dynamics and Topology of Polymer Rings Immersed in a Host Matrix of Longer Linear Polymers: Results from a Detailed Molecular Dynamics Simulation Study and Comparison with Experimental Data

“…In all MD simulations, we used the modified TrAPPE united-atom (UA) force-field introduced by Fischer et al [ 42 , 43 ], which has been thoroughly validated through extensive comparisons of its predictions for several material properties (density, mean square radius-of-gyration, self-diffusion coefficient, dynamic structure factor, etc.) of low and high molecular weight linear and ring PEO melts with published simulation [ 44 ] or experimental [ 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 ] data and/or the predictions of other force fields reported in the literature [ 53 ]. The simulations were executed with the GROMACS [ 54 ] simulation software in the isothermal–isobaric (NPT) statistical ensemble by applying the Nosé–Hoover thermostat [ 55 , 56 ] coupled with the Parrinello–Rahman [ 57 ] barostat to keep the temperature T and the pressure P fixed at the desired values ( T = 413 K and P = 1 atm).…”
