The ester, isopentyl acetate was synthesized, which had the smell of bananas. In this experiment, 3.99 g of isopentyl acetate was formed by the direct esterification of acetic acid with isopentyl alcohol, as seen in table 1. The sulfuric acid was used as a catalyst in the reaction.
How does Fischer esterification of isopentyl acetate take place?
An excess of isopentyl acetate was used to shift the reaction to the right so that esterification could occur. During isolation, the excess acetic acid and isopentyl alcohol was removed with sodium bicarbonate, and the isopentyl acetate was further purified after through drying with anhydrous sulfate and through distillation.
Which is more stable isopentyl alcohol or acetic acid?
The major product that was formed from the Fischer Esterification of isopentyl alcohol and acetic acid was isopentyl acetate. This is because the ester formed is the equatorial position, which makes the compound more stable than cis-4-tert-butylcyclohexanol.
