Excess molar volumes and viscosities of 1-propanol plus ethylene glycol, plus ethylene glycol monomethyl, plus ethylene glycol dimethyl, plus diethylene glycol dimethyl, plus triethylene glycol dimethyl, plus diethylene glycol diethyl, and plus diethylene glycol dibutyl ethers at 298.15K
Excess molar volumes V-m(E) and viscosities eta 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), CH3O2H4OH, diethylene glycol dimethyl ether (bis(2-methoxyethyl) ether), CH3(OC2H4)(2)OCH3, triethylene glycol dimethyl ether (1,2-bis(2-methoxyethoxy)ethane), CH3(OC2H4)(3)OCH3, and diethylene glycol diethyl ether (bis(2-ethoxyethyl) ether), C2H5(OC2H4)(2)OC2H5, at 298.15 K. Viscosity measurements have also been made for the mixtures l-propanol + ethylene glycol dimethyl ether (1,2-dimethoxyethane), CH3OC2H4OCH3, and + diethylene glycol dibutyl ether (bis(2-butoxyethyl) ether), C4H9(OC2H4)(2)OC4H9, 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.
