Excess molar volumes and viscosities of binary liquid mixtures of ethyleneglycol dimethyl ether plus ethylene glycol monomethyl, plus diethylene glycol monomethyl, and plus triethylene glycol monomethyl ethers at 298.15 and308.15 K

Excess molar volumes V-m(E), and viscosities eta have been measured as a fu nction of mole fraction for binary liquid mixtures of ethylene glycol dimet hyl ether (1,2-dimethoxyethane), CH3OC2H4OCH3, with diethylene glycol monom ethyl ether (2-(2-methoxyethoxy)ethanol), CH3(OC2H4)(2)OH, and triethylene glycol monomethyl ether (2-[2-(2-methoxyethoxy)ethoxy]ethanol), CH3(OC2H4)( 3)OH, at 298.15 and 308.15 K and at atmospheric pressure. Measurements of v iscosity at 298.15 and 308.15 K and excess molar volume at 308.15 K have al so been made for the mixtures ethylene glycol dimethyl ether + ethylene gly col monomethyl ether (2-methoxyethanol), CH3OC2H4OH, over the whole composi tion range. Density rho of the mixtures have been calculated from the resul ts. All of the systems show negative deviation from a mole fraction average in viscosity. The excess molar volumes for all of the mixtures are negativ e over the entire composition range.
