Densities and viscosities of the binary mixtures of p-cresol + ethylene glycol and p-cresol + methanol mixtures have been measured at different temperatures and atmospheric pressure, over the entire composition range. From these data, excess molar volumes and viscosity deviation were calculated for each of the systems. The densities and viscosities of pure components have been compared with those reported by other authors available in the literature. The excess molar volumes, V-E, and viscosity deviations, Delta eta, were fitted to a Redlich-Kister equation, and the coefficients of the Redlich-Kister equation and estimate the standard error are also presented.
