Consider the phase diagram below for a mixture of chloroform and methanol, looking at how the boiling point changes with composition at constant pressure. If you started with a solution that was Xchloroform = 0.1 at a temperature of 333 K, is it possible to use fractional distillation to purify this solution to nearly 100% chloroform? Approximately what concentration (in mole fraction) would you expect you could achieve through fractional distillation? Curves calculated by mod. UNIFAC (Dortmund) Temperature Minimum Azeotrope...
