Isopentyl (Isoamyl) Acetate Synthesis and Extraction
12.0 g of isopentyl alcohol mixed with 20 mL glacial acetic acid and 1.2 mL of H2SO4. This is refluxed for an hour. Must use 20 mL of diethyl ether as the extraction solvent. What is the procedure for the extractions (to MAXIMIZE THE YIELD) and volumes? (i.e. How much water, NaCl, sodium bicarbonate and in what order)?
