Excess Molar Volumes and Viscosities for Glycol Ether-Water Solutions at the Temperature 308.15 K - Ethylene-Glycol Monomethyl, Diethylene Glycol Monomethyl, and Triethylene Glycol Monomethyl Ethers
Excess molar volumes (V-m(E)) and viscosities (eta) have been determined as a function of mole fraction for binary liquid mixtures of water with ethylene glycol monomethyl ether (2-methoxyethanol), CH3O(CH2)(2)-OH, diethylene glycol monomethyl ether (2-(2-methoxyethoxy)ethanol), CH3O(CH2)(2)O(CH2)(2)OH, and triethylene glycol monomethyl ether (2-[2-(2-methoxyethoxy)ethoxy]ethanol), CH3O(CH2)(2)O(CH2)(2)O(CH2)(2)-OH, at 308.15 K. Densities (rho) of the mixtures have been calculated from the results. The excess volumes are negative over the entire composition range for the systems studied. The results for V-m(E) and eta are discussed in terms of interactions of water with an amphiphilic molecule.
