Consider the following PT projection of a phase diagram typical of DO/2-methylpyridine systems. Plot T-x1-y diagrams for the indicated pressures and P-x-y diagrams for the indicated temperatures. Clearly indicate any three-phase lines, azeotropes, critical end points, and lines for coexisting vapor and liquid phases on your diagrams.
