STEAM DISTILLATION EXERCISES

1. Indicate which of the following statements is true (T) or false (F), by placing a check

in the appropriate space

Steam distillation would be the procedure of choice for separating mixtures of:

T F

_ _ a. methanol (bp 65^oC) and water (methanol is completely miscible with water)

_ _ b. p-dichlorobenzene (bp 174^oC) and water (p-dichlorobenzene is insoluble in

water)

_ _ c. 1,2-ethanediol (ethylene glycol, bp 196^oC) and water (1,2-ethanediol is

completely miscible with water)

_ _ d. polyisoprene (non-volatile) and water (polyisoprene is completely insoluble in

water)

2. Explain your answers to each part of question 1.

2. The boiling point during steam distillation is usually less than 100^oC. Explain your

answer.
