Densities, speeds of sound, and refractive indices of binary mixtures of decan-1-ol with 2-methylphenol (o-cresol), 3-methylphenol (m-cresol), 4-methylphenol (p-cresol), and methyl phenyl ether (anisole) were measured over the entire range of composition from T = (298.15 to 308.15) K and at a pressure of 0.1 MPa. The experimental values of densities were used to calculate the excess molar volumes of the binary liquid mixtures. Excess molar volumes have been fitted to the Redlich−Kister polynomial equation to derive the binary coefficients and the standard errors between the experimental and the calculated quantities. The excess molar volumes are negative over the entire composition range for the binary mixtures of decan-1-ol with m-cresol and p-cresol and give an s-shaped curve with o-cresol at the high mole fraction region of o-cresol. For the binary mixtures of decan-1-ol with anisole, the excess molar volume is positive.
