1. Wash with deionized water 2. Wash with 5% aqueous sodium bicarbonate solution 3. Dry liquid water with sodium sulfate

Explanation / Answer

Synthesize, and purify, isopentyl acetate from isopentyl alcohol and acetic acid.

Procedure flowchart:

1)isopentyl alcohol + acetic acid + Sulfuric Acid

2)Place the aqueous phase in conical vial

3)Add 10 mL of distilled water; stopper the funnel and mix,

Allow the layers to separate and un stopper the funnel.

4)Drain the lower aqueous layer into a beaker

5)Extract the organic layer with 5 mL of 5% sodium bicarbonate

6)Again drain the lower aqueous layer

7)Extract the organic layer with another 5 % sodium bicarbonate and drain the lower aqueous layer

8) Transfer the crude ester to a clean, dry 50 mL flask and add approximately 1.0 gram of anhydrous sodium sulfate. Mix.

9) dry for 10 minutes

1)isopentyl alcohol + acetic acid + Sulfuric Acid
