Question

A mixture of aniline and water in an industrial setting is most efficiently separated utilizing which of the following techniques, based on the principle of combined vapor pressures ($P_T = P_{org} + P_{water}$)?

Prashant Kotian · Accepted Answer

Correct answer: B. Steam distillation is employed to separate substances which are steam volatile, immiscible with water, and possess a high vapor pressure. The aniline-water mixture boils when the sum of their vapor pressures equals atmospheric pressure, protecting the aniline from high-heat degradation.
