P-xy T-xy Diagrams. Definition: The P-xy and the T-xy are diagrams that represent the liquid and vapour equilibrium for a binary mixture. The component that is graphed is the most volatile one because is the one that will evaporate first during the distillation process. On the x-axis goes the mole fraction x,y (for liquid phase and vapour phase ... Benzene is a liquid at standard conditions. However, if heated it becomes a gas, and when cooled it becomes a solid. The phase diagram for benzene shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the benzene boiling point with changes in pressure.

Benzene is a clear, colorless, highly flammable and volatile, liquid aromatic hydrocarbon with a gasoline-like odor. Benzene is found in crude oils and as a by-product of oil-refining processes. In industry benzene is used as a solvent, as a chemical intermediate, and is used in the synthesis of numerous chemicals.
