Phenol water phase diagram experiment

Web14. dec 2014 · Phase diagram for ternary systems which contain ethanol/toluene/water is represented using a triangle diagram. The real curve was determined in this experiment. Water and toluene form a two-phase system because they are only slightly miscible. Ethanol is completely miscible with both toluene and water. Web– 5 – Task 21 – Phase equilibrium of liquid – liquid ternary systems Water and toluene are both liquids at 25°C and are almost completely immiscible. So shaking together some water and some toluene, two phases are obtained; an aqueous phase containing traces of toluene and a toluene phase containing traces of water. Adding methanol
