Exercise 1.06 – Predicting Azeotropes For the system methanol(1)/methyl acetate(2), the following provide a reasonable correlation for the activity coefficients: In y1 = Ax, and In y2 = Ax where A = 2.771 – 0.00523T In addition, the following Antoine equations provide vapor pressures for methanol and methyl acetate: 3643.31 2665. 54 In Pjat = 16.59158 - and In Pat = 14. 25326 - т- 3.424 Т-53.424 where T is in Kelvins and the vapor pressures are in kPa. Assuming modified Raoult's law at T = 318.15 K, calculate: a. P and y, for x1 b. P and x; for y, = 0.60 c. the azeotropic pressure and the azeotropic composition Yi = 0.25 %3D %3D
