Experiment 5: Preparation of Synthetic Banana Oil Name: Jill LeBard Date: April 25, 2008 Results Isopentyl acetate was obtained in a 36% yield from a Fischer esterification upon the addition of acetic acid and isopentyl alcohol. Upon heating the acetic acid and isopentyl alcohol mixture, the color changed from yellow to dark red. When the solution was washed with 50 mL of water two layers were formed, the top being a cloudy black and the bottom being red. When sodium bicarbonate was added the two layers were yellow and clear. After the first mixture had heated and cooled, it gave off a strong juicy fruit or banana odor. The final product of isopentyl acetate was collected by distillation between 136 0 C-140 0 C. Discussion Statement of the Problem : Prepare isopentyl acetate from acetic acid and isopentyl alcohol with there being no more than 2% acetic acid in the final product in order to make synthetic banana flavoring. Working Hypothesis
