Q 1: If 100 kg of a solution of acetic acid (C) and water (A) containing 25% acid is to be extracted three times with isopropyl ether (B) at 20°C, using 40 kg of solvent in each stage. (a) determine the quantities and compositions of the various streams. (b) How much solvent would be required if the same final raffinate concentration were to be obtained with one stage: Equilibrium data: Water layer Isopropyl ether layer Acetic acid, 100y* Wt % acetic acid, Isopropyl ether Isopropyl ether 100x Water Water 0.18 0.37 0.5 0.7 99.3 98.9 0.69 98.1 97.1 1.2 1.41 1.5 98.4 2.89 6.42 95.5 91.7 1.6 0.79 0.8 1.9 1.93 1.0 97.1 13.30 84.4 2.3 3.4 4.82 1.9 93.3 25.50 71.1 11.40 3.9 84.7 36.70 58.9 4.4 21.60 6.9 71.5 44.30 10.6 45.1 37.1 31.10 10.8 58.1 46.40 16.5 36.20 15.1 48.7
