Question

Consider the ternary phase diagram as the scale is given as mass fractions. The equilibrium concentrations for two phases of the ternary phase system of ethanol (A) water (B) and ethyl acetate (C) at 20 °C and atmospheric pressure are given in Table below. Phase a Phase B wt% A wt% B wt % C wt% A wt % B wt % C 0 92 8 0 3 97 7.6 84 8.4 5.5 5.3 89.2 14 76 10 10 8.6 81.4 20 63 18 18 21 61 23 46 31 23 46 31 i) Plot the ternary phase diagram including tie lines on the graph. ii) Show the Plait point / isothermal critical point on the diagram. Firstly, 216 g of ethanol, 864 g of water and 720 g of ethyl acetat are mixed at 20 °C, and 1 atm in separation flaks, and then it is separated into two phases which are at equilibrium. iii) Indicate the mixture point M on the graph. iv) Write the names of each phase as a and $\beta$ on the graph after the phase separation of the mixture. v) Find the compositions after phase separation of the mixture. vi) Calculate mass amount of each component in each phase.
