Volumetric properties of binary mixtures of o-cresol plus poly (ethylene glycols) in the temperature range 288.15-308.15 K and atmospheric pressure

摘要

The density of binary mixtures of (o-cresol + poly(ethylene) glycol (PEG)200, + PEG-300 and + PEG-400) has been measured over the entire range of composition at temperatures (288.15, 293.15, 298.15, 303.15 and 308.15 K) and atmospheric pressure. Excess molar volumes (VEm) of the mixtures were calculated and correlated by the Redlich-Kister equation. Temperature dependences of the Redlich-Kister coefficients are also presented.
