Abstract

Densities and excess molar volume data for various glycol (mono-, di-, tri-, and polyethylene glycol-400) aqueous solutions have been measured over wide ranges of compositions and temperatures generally from (273.15 to 363.15) K at atmospheric pressure. All the measurements were performed using a digital vibrating tube densimeter. Densities of mono-, di-, and triethylene glycol in pure form and those of polyethylene glycol (400) are correlated using the Daubert et al. correlation. Excess molar volumes of glycol aqueous solutions have been correlated with mole fraction polynomials. For all the studied systems, excess molar volumes are found to be negative, increasing from monoethylene glycol to polyethylene glycol-400.
