Experimental data of physical properties such as density in binary mixtures are of relevance from the fundamental and engineering point of view. For example, the knowledge of excess molar volumes can provide information about the specific molecular interactions in the mixture. In the other hand, thermophysical properties are required for the design of industrial processes. In this work, densities of o-cresol (1) + m-cresol (2) were determined at temperatures from 313 to 363 K and pressures up 25 MPa. Densities of each mixtures were correlated using a 6-Parameter equation. The excess molar volumes were obtained for the whole range of measurements. The isothermal compressibility, isobaric thermal coefficient and the internal pressure were derived from the densities. Rosal et al. [1] have measured previously densities of binary mixtures of cresols at atmospheric pressure at temperatures form (313.15 to 333.15).
