What is synthesis of isopentyl acetate?
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.
How do you make isopentyl acetate?
1) Mix isopentyl alcohol (5.4 mL, via burette) and glacial acetic acid (8.5 mL, via graduated cylinder) in a round-bottom flask. Carefully add 20 drops of conc. H2SO4 to the mixture. 2) Put in a few boiling chips and assemble the reflux apparatus (Figure 1).
How is isoamyl acetate formed?
Isoamyl acetate is produced from a reaction between amyl alcohol and acetyl coenzyme A catalyzed by the enzyme isoamyl alcohol acetyl transfer- ase11.
What reaction will result in the synthesis of banana oil?
The reaction mechanism involves initial protonation of the carboxyl group, nucleophilic attack by the hydroxyl, proton transfer, and loss of water followed by loss of the catalyzing acid to produce the ester. The process is thermodynamically controlled yielding the most stable ester product.
What is the molecular formula of isopentyl acetate?
C7H14O2
Isoamyl acetate/Formula
What is the Iupac name for isopentyl acetate?
isoamyl acetate (CHEBI:31725) is a acetate ester (CHEBI:47622) IUPAC Name. 3-methylbutyl acetate.
Why is anhydrous sodium sulfate added to the isopentyl acetate?
Your collected isopentyl acetate must be dried using a dehydrating agent. You should use anhydrous sodium sulfate (Na2SO4) to dry your chemical.
What is the molecular formula of isoamyl acetate?
What functional groups are in isopentyl acetate?
Isopentyl acetate belongs to the family of Carboxylic Acid Esters. These are carboxylic acid derivatives in which the carbo atom from the carbonyl group is atached to an alkyl or oaryl moiety through an oxygen atom (forming an ester group).
What is the correct empirical formula for isopentyl acetate?
Isopentyl acetate (T3D4851)

How is isopentyl acetate prepared in an experiment?
In this experiment, you will prepare isopentyl acetate by reacting an excess of acetic acid with isopentyl alcohol. You will use sulfuric acid to catalyze the reaction. After the reaction is complete, you will remove the excess acetic acid and sulfuric acid from the reaction mixture by extraction with sodium hydrogen carbonate.
Which is the best dehydrating agent for isopentyl acetate?
Isolation of Product: Your collected isopentyl acetate must be dried using a dehydrating agent. You should use anhydrous sodium sulfate (Na 2 SO 4) to dry your chemical. Add about 2 grams of the anhydrous sodium sulftate (this amount of anhydrous sodium sulfate is enough to bind over 2.5 grams of water).
How is isoamyl acetate collected in a flask?
The entire product is added to a 50-mL round bottom flask, containing several boiling stones to prevent super-heating and bumping of the crude isoamyl acetate during distillation. A simple distillation is performed to collect the isoamyl acetate. The flask is heated in using a heating manifold.
How is the Fischer esterification of acetate catalyzed?
The reaction proceeds by way of a nucleophilic substitution at the acyl carbon of the carboxylic acid. When catalyzed by a strong acid, usually sulfuric acid or p‐toluenesulfonic acid, the reaction is called the Fischer esterification.
