A mixture of propionic and n-butyric acids, which can be assumed to form ideal solutions, is to be separated by distillation into a distillate containing 95 mol% propionic acid and a bottoms product containing 98 mol% n-butyric acid. Determine the type of condenser to be used and estimate the distillation-column operating pressure.
