You are given 2.00 g of a mixture of phenol, aniline, phthalic acid and methyl benzoate. Describe, how you would use an acid-base extraction technique to separate all three compounds by drawing the flowchart. Propose another way of extraction, where different order of extraction is used (e.g., adding the acid first instead of a base)

Solutions

Expert Solution

phthalic acid will become salt in mild base like NaHCO3 and dissolves in water. After we can acidify with acid solution and organic solvent where phthalic acid will come to organic layer that to be concentrated to get it as solid.

phenol will become salt in strong base like NaOH and dissolves in water. After we can acidify with acid solution and organic solvent where Phenol will come to organic layer that to be concentrated to get it as solid.

aniline will become salt in HCl and dissolves in water. After we can acidify with basic solution and organic solvent where aniline acid will come to organic layer that to be concentrated to get it as solid.

You are preparing triphenyl carbinol by a grginard synthesis. First you prepare methyl benzoate, and set aside 4.40 grams of the purified ester for later use. You then prepare the grignard reagent ( phenylmagnesium bromide ) by reacting 1.78 grams of magnesium with 12.01 ml of bromobenzene. You add the 4.40 grams of methyl benzoate to the freshly prepared grignard reagent to form an addition product. Finally, after hydrolyzing the grignard addition product, you obtain 5.27 grams of the final...
