A feed mixture weighing 200 kg of unknown composition containing water, acetic acid, and isopropyl ether is contacted in a single stage with 280 kg of a mixture containing 40 wt % acetic acid, 10 wt % water, and 50 wt % isopropyl ether. The resulting raffinate layer weighs 320 kg and contains 29.5 wt % acetic acid, 66.5 wt % water, and 4.0 wt % isopropyl ether. Determine the original composition of the feed mixture and the composition of the resulting extract layer.
Consider the reaction of 5.0 moles of CS2 and 3.0 moles of NaOH according to the following reaction 3 CS2 + 6 NaOH -> 2 Na2CS3 + Na2CO3 + 3 H2O.
