A solution containing 10mol% of CS2 (1) and 90mole% acetone (2) is to be separated in a reversible continuous flow isothermal, isobaric separator into pure acetone and an aeotrope that forms at 39.250C under atmospheric pressure. The azeotrope contains 61mole % CS2. Estimate the work of separation if the feed solution is liquid at 39.250C and the products are withdrawn at the same temperature. At 39.250C, 1 2 604 ; 400 .
