First Week Add 10 mL of glacial acetic acid to 5 mL of isoamyl alcohol in a 125 mL Erlenmeyer flask. (Because of the very unpleasant odor of acetic acid, dispensing of the acid and mixing with alcohol must be performed under the hood). Carefully add 3 mL of concentrated sulfuric acid (being careful not to wet the neck of the flask which will be in contact with the cork stopper), swirl the mixture, stopper tightly with a cork and store at room temperature until the next lab period. NOTE: Extreme care must be exercised in order to avoid contact with concentrated sulfuric acid. It will cause serious burns if it is spilled on the skin. If it comes in contact with the skin or clothes, it must be washed off immediately. In addition, sodium bicarbonate may be used to neutralize the acid. Clean up all spills, immediately! Second Week Using the hood again pour the solution into a 250 mL beaker containing 40 mL of water and neutralize it (pH paper) by adding saturated sodium carbonate solution in small portions, stirring the mixture with a glass rod. The neutral mixture is transferred to a 125 mL separatory funnel, the aqueous phase is removed and the upper ester layer is washed with 10 mL of water. Separate the ester and place it in a 50 mL Erlenmeyer flask. Add small portions of anhydrous potassium carbonate and let the ester dry for 10 minutes. Gravity filter the liquid into a 25 mL round-bottom flask. Add a boiling chip and distill the ester, collecting the product boiling at 138-141°C in a small, tared Erlenmeyer flask. Analyze the product using IR spectroscopy.
