PVT PROPERTY MEASUREMENTS FOR LIQUID CHLOROBENZENE AND 1,2-DICHLOROBENZENE FROM (278 TO 338) K AND (0.1 TO 300) MPA

The effect of pressure on the volume in the liquid phase for chloroben zene and 1,2-dichlorobenzene has been measured relative to their volum es at 0.1 MPa with a bellows volumometer for pressures up to 300 MPa o ver the temperature range (278.15 to 338.13) K. The experimental volum e ratios have been represented by two sets of equations to enable inte rpolation and extrapolation of volumetric properties. The results of o ne of these representations suggests a means of extrapolating the volu metric properties of these chloro-substituted benzene derivatives. Iso thermal compressibilities, thermal expansivities, normalized volume fl uctuations, and the change in the isobaric heat capacity from its valu e at 0.1 MPa have been calculated from the results.
