When might a distillation be chosen over recrystallization or extraction to separate a mixture of compounds?
Homework Answers
If the boiling point of both compounds are far apart from each other value then distillation can be easily take place without the risk of mixing of two compounds.

A mixture of two compounds, A and B, was separated by extraction.
After the compounds were dried, their masses were found to be: 117
mg of compound A and 93 mg of compound B. Both compounds were
recrystallized and weighed again. After recrystallization, the mass
of compound A was 95 mg and the mass of compound B was 85 mg.
Calculate the percent recovery from recrystallization for both
compounds.

Which technique, recrystallization or distillation, would be most likely to separate each of these pairs? Explain your answers in complete sentences. Butylbenzene and 1-chloro-2,3,3-trimethylbutane Triiodomethane and 1-nitro-2-naphthol 2. For each pair, state whether you could get away with simple distillation or whether you would need fractional distillation. Explain your answers in complete sentences. ethylcyclohexane and bromocyclohexane cyclooctane and methyl acetate Is it possible to obtain pure (200-proof) ethanol, using fractional distillation, from a fermentation mixture that contains equal...

An extraction was performed using mixture of the compounds below. First the organic mixture was dissolved in dichloromethane, treated with acid, and separated. The organic layer was then treated with base and separated. Sort the compounds based which layer it was in at the end of the extraction.
