THERMOPHYSICAL PROPERTIES OF M-CRESOL AS A FUNCTION OF TEMPERATURE (303 TO 503 K) AND PRESSURE (0.1 TO 400 MPA)

Measured and derived thermophysical properties of m-cresol are reporte d for pressures up to 400 MPa at temperatures from 303 to 503 K. Isoba ric thermal expansivities were measured by pressure-scanning calorimet ry from 303 to 503 K and 0.1 to 400 MPa. The specific volume at 353 K was determined by pycnometry at atmospheric pressure and calculated fr om isothermal compressibilities measured as a funtion of pressure up t o 400 MPa. Specific volumes at other temperatures and pressures are ca lculated from isothermal compressibilities measured as a Function of p ressure up to 400 MPa. Specific volumes, isothermal compressibilities, thermal coefficients of pressure, and isobaric and isochoric heat cap acities at pressures up to 400 MPa are derived at several temperatures . The effects of pressure on the isobaric heat capacities of m-cresol, n-hexane, and water are compared. The effects of self-association of m-cresol are apparent in both the thermal expansivity and the heat cap acity data.
