The fusion temperature as a function of pressure for benzene, nitrobenzene, bromobenzene, and chlorobenzene at pressures up to 3500 MPa has been determined. The new experimental data are an extension to higher pressures and temperatures of previous data and fitted by the equation T fus = T 0(1 + Δp/a 1) a 2 exp(−a 3Δp). Changes of the molar enthalpy and the molar internal energy on fusion were calculated using the parameters of the fitted equation. Comparisons with data from references show that the experimental data, parameters of fitted equations, molar enthalpy changes, and molar internal energy changes are reliable.
