Figure 1
Phase diagram of benzene compiled from the experimentally observed transformations. L denotes a liquid; G a gas; S I–IV the solid-state phases, P I–III the polymers. The triple points are denoted as TP1 [1.20 (5) GPa and 477 K; Akella & Kennedy, 1971BB1], TP2 [2.25 (5) GPa and 608 (5) K; Akella & Kennedy, 1971BB1], TP3 (5.1 GPa and 697 K; Cansell et al., 1993BB16). Tb is the boiling point at 299 K and 0.1 MPa; Cp is the critical point at 4.89 MPa and 562 K (Tsonopoulos & Ambrose, 1995BB49). Points A, B, C and D outline the polymerization region – see the text. The inset magnifies the 200–600 K and 0–1.2 GPa region.
