In the manufacture of aniline, the condensed reactor products are separated in adecanter. The decanter separates the feed into an organic phase and an aqueousphase. Most of the aniline in the feed is contained in the organic phase and most ofthe water in the aqueous phase. Using the data given below, calculate the streamcompositions.Data:Typical feed composition, including impurities and by-products, weight per cent:water 23.8, aniline 72.2, nitrobenzene 3.2, cyclo-hexylamine 0.8.Density of aqueous layer 0.995, density of organic layer 1.006. Therefore, theorganic layer will be at the bottom.Solubility of aniline in water 3.2 per cent w/w, and water in aniline 5.15 per centw/w.Partition coefficient of nitrobenzene between the aqueous and organic phases:Corganic/Cwater D 300Solubility of cyclo-hexylamine in the water phase 0.12 per cent w/w and in theorganic phase 1.0 per cent w/w.
