11.6: Nucleophilic Acyl Substitution Reactions in the Laboratory
2019年8月12日 · Acid-catalyzed synthesis of flavor compounds such as isopentyl acetate (an ester with the flavor of banana) is simple to carry out in the lab. In this esterification reaction, acetic acid is combined with isopentyl alcohol along with a catalytic amount of sulfuric acid.
In this laboratory experiment, you will prepare banana oil (isopentyl acetate) by the Fischer esterification of acetic acid and isopentyl alcohol (figure 3). The reaction will be catalyzed by the addition of sulfuric acid. Once the reaction is complete, a distillation will be performed to isolate the pure organic ester, which will be a liquid.
The purpose of this experiment is to synthesize isopentyl acetate (3-methylbutyl acetate) via an esterification reaction between acetic acid and isopentyl alcohol (3-methylbutanol), using concentrated sulfuric acid as a catalyst. The product will be washed, distilled, then characterized using NMR spectroscopy. Literature
In your reaction, the synthesis of banana oil – isopentyl acetate, you will be using isopentyl alcohol (3-methyl-1-butanol) and acetic acid (ethanoic acid, see Figure 3).

"Experiment 14A: Isopentyl Acetate" by Ethan Sevedge - JCCC
2021年5月26日 · In this experiment, the synthesis of isopentyl acetate via the Fischer esterification of acetic acid with isopentyl alcohol was studied.1 Sulfuric acid acted as a catalyst for the reaction. A large excess of acetic acid and the addition of heat to the system shifted the reaction’s equilibrium to the right, favoring the ester.
Experiment 11 Synthesis of Isopentyl Acetate - Studocu
The mechanism of the synthesis involves a few steps. First, protonation of acetic acid by sulfuric acid. Second, nucleophilic attack of the protonated acetic acid by the isopentyl alcohol. Third, proton transfers to protonate an OH group into a H 2 O …
Synthesis of Isopentyl Acetate (Banana Oil) - Thermo Fisher Scientific
The purpose of this experiment is to synthesize isopentyl acetate (3-methylbutyl acetate) via an esterification reaction between acetic acid and isopentyl alcohol (3-methylbutanol), using concentrated sulfuric acid as a catalyst. The product will be washed, distilled, then characterized using NMR spectroscopy.
A carboxylic acid and an alcohol can be combined to make an ester using a catalytic amount of sulfuric acid. In this lab, we will use acetic acid and isopentyl alcohol to form isopentyl acetate, which is known as banana oil because it smells like bananas. It is found
