Abstract
Density was measured over the whole concentration range for the binary system of poly(ethylene glycol) 300 (PEG 300) + water at five temperatures from (298.15 to 318.15) K. The density ( ρ) is fitted to calculate the excess molar volume ( V m E ) and viscosity deviation (Δ η). The computed results are fitted to a Redlich–Kister equation to obtain the coefficients and estimate the standard deviations between the experimental and calculated quantities. The values of V m E for all mixtures are negative, while the values of Δ η are positive over the entire composition range.
