100%
Describe in words and illustrate by means of complete chemical equations, how a mixture of 1.25 g of benzoic acid tert-butylbenzene can be separated. Apply what you learned in organic 1, reviewing in your manual the experiment of separation of 2 components by liquid-liquid extraction.
Transcribed Image Text:Dissolved in Diethyl
Ether
Benzoic acid and
Tert-butylbenzene
Add an aqueous and basic solution of NaOH then
stir and separate the phases
salt (cojugated base) dissolved in water
Kaqueous phase) of alkaline pH.
lower phase
dissolved in diethyl ether (organic
phase).contains water residues.
upper phase
It is acidified with
50% HCI to protonate the
conjugate base
which is insoluble in water
Magnesium sulfate is added
anhydrous (M9SO,) to dry
it is filtered through a
Büchner by suction
dissolved in diethyl ether and dry
1) is filtered by gravity (or decanted)
2) the solvent is evaporated (diethyl ether)
heating on the sand bath in the extractor
it is dried at 70 * C
