Determine if either simple distillation set-up or fractionating set-up is most efficient for the following mixtures (for distillation)
2-butanone and t-butyl alcohol
Diethylene glycol
a mixture of diethyl ether and chlorobenzene
basics recall=
WHAT IS DISTILLATION
distillation is a method to separate a mixture of the liquid with the help of difference in boiling point. the process involves evaporation and condensation
what is a fractional distillation
multiple simple distillations in one go are fractional distillation. used in cases where liquids have closer boiling points
applying the principle to our examples
2-butanone and t-butyl alcohol
2-butanone = boiling point = 79.64
t-butyl alcohol = boiling point = 82
very clear that boiling points are closer and we need to use fractional distillaion for separation
Diethylene glycol = boiling point = 244
huge difference = simple distillation can be used
a mixture of diethyl ether and chlorobenzene
diethyl ether = boiling point = 34.6
chlorobenzene = boiling point = 137
huge difference simple distillation worth of doing
