Thermodynamic Properties of Water + Ethylene Glycol at 283.15, 293.15, 303.15, and 313.15 K

Abstract

Excess volumes (VE), viscosity deviation (Δη), excess refraction (ΔR), and surface excess (σE) of water + ethylene glycol have been determined over the entire composition range at a number of temperatures. The results are fitted to a Redlich−Kister equation, and the corresponding parameters are derived. All the properties have negative values and exhibit a minimum at the same water-rich region of the solution. The results are discussed in terms of molecular interactions.
