Experimental densities, viscosities, and heat capacities at different temperatures were measured over the entire mole fraction range for the binary mixture of ethylene glycol + water. Density values were used in the determination of excess molar volumes, V E . The excess volumes, V E , are fitted as a function of the mole fraction to a polynomial. ∆η was fitted to the Redlich-Kister equation. The excess volumes are negative over the entire composition at the lower temperatures. They show a U-shaped concentration dependence and decrease in absolute value with increasing temperature. At high temperatures, the excess molar volume shows an S-shaped dependence. ∆η values are negative over the entire range of mole fraction and have a very similar trend to that for V E . The heat capacities of mixtures have the maximum values at x 1 ) 0.0312.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
