Figure 13
Phase diagram of benzene, C6H6, (top); its yellow-marked part expanded 4000 times (centre) along the pressure axis, to show the boiling curve ending with critical point (CP); and (bottom) the diagram with pressure scale enhanced 300 times further to illustrate the sublimation curve and the triple point (TP, at 4.785 kPa and 278.7 K). The diagrams have been drawn to scale: note the change in pressure units (GPa vs MPa and kPa). The dotted lines (top diagram) mark phase boundaries not confirmed structurally. |
