Q: BenZoic acid in a solution with toliene is to be extra using water as solvent initially containing 0.01% of benzoic acid. The benzoic acid concentration in the toluene feed is 2% by weight and 95% of the benzoic acid is to be recovered in the water phase. A counter current mixer - settler installation equivalent to five theoretical stages is available. If the solvents may be regarded as immiscible, what is ratio of water to toluene should be employed, and what is the composition of the final extract phase? in the following cases: (A) The equilibrium data are: X (10-3) Y (10-4) 6. 10 14 18 22 26 2.9 7.2 10.1 12.4 14.0 15.6 16.8 Where: X is the weight of benzoic acid / weight of toluene.

Question
Q: Benzoic acid in a solution with toluene is to be extracted using water as solvent
initially containing 0.01% of benzoic acid. The benzoic acid concentration in the
toluene feed is 2% by weight and 95% of the benzoic acid is to be recovered in the
water phase. A counter current mixer - settler installation equivalent to five theoretical
stages is available. If the solvents may be regarded as immiscible, what is ratio of water
to toluene should be employed, and what is the composition of the final extract phase?
