The excess molar volumes of Water+Ethylene Glycol binary mixture at 313.15 K, Acetic Acid+Ethylene Glycol binary mixture at 283.15 K, 293.15 K, 303.15 K, 313.15 K and Water+Acetic Acid+Ethylene Glycol ternary mixture at 283.15 K, 293.15 K were measured by using a vibration tube densimeter. The binary data were correlated to the Redich-Kister polynomials and the excess volumes of ternary system were estimated by utilizing the parameters regressed from the experimental excess volumes of the binary ann ternary mixtures.
