  We report new results on the liquid to solid phase transition of benzene. We
determine experimentally and investigate the properties of a number of
parameters of the benzene metastable state under different pressures (from 0.1
up to 2200 atm). It is shown that the supercooling, pressure drop, incubation
period, time of abrupt transition from the metastable state to the crystalline
state, and time of isothermal freezing all decrease as the external pressure
increases, then they all vanish at 2200 atm and 356 K which may mark the
end-point of metastability. Quadratic interpolation formulas for these
parameters are provided. The densities and molar heat capacities of supercooled
benzene under different pressures have been calculated too.
