Phase equilibrium and metastability of liquid benzene at high pressures.

This work is mainly an investigation of some of the liquid-to-solid properties of pure benzene on a restricted domain of high pressures (20.6< or =P< or =102.9 MPa). Newly obtained equilibrium experimental data and recently developed analytical equation of state are exploited and compared with each other and with previous experimental data. Curves fitted to the pressure, volume discontinuity, and enthalpy change at liquid-to-solid equilibrium points are provided. Concerning the metastable liquid benzene, both experimental and theoretical data for the minimum nucleation temperatures (limits of liquid metastability) are provided and correlated to each other.
