Should include purpose, materials, method, data, and conclusion (in this should be which sample was the isoamyl acetate, what your percent yield of isoamyl acetate was, and the reaction mechanism-aka arrow pushing to how isoamyl acetate was made.) Synthesis of Isopentyl Acetate Report Sheet Name: Partner: Calculate your percent yield Questions: 1.

What is the theoretical yield of isoamyl acetate that comes from isoamyl alcohol and acetic acid? There is 8.5 mL of isoamyl alcohol and 15.0 mL of acetic acid.

Discussion Isoamyl acetate was synthesized by refluxing 1 eq of isopentanol with 4 eq of acetic acid, and 0.5 eq of concentrated sulfuric acid as a catalyst and a dehydrating agent to ensure reaction equilibrium lies far towards the products. The reaction mixture was then added to water and liquid-liquid extraction was conducted.

Evaluation of experimental results 2.08g of isoamyl acetate was obtained with a percentage yield of 40.4%. This low yield is due to firstly, the theoretical yield of the synthesis is around 80% [1] as Fischer esterification being a reversible reaction, does not go to completion. Secondly, isoamyl acetate …show more content…

The purpose of this experiment was to prepare isoamyl acetate from isoamyl alcohol and glacial acetic acid by Fischer esterification. Introduction Esters are derivatives of carboxylic acids. Instead of having the –COOH group, an ester will include an alkoxy substituent which is a hydrocarbon group of some kind attached to the oxygen molecule ...

The byproduct of the synthesis of isoamyl acetate was? Select one: a. sulfuric acid b. water c. isoamyl alcohol d. acetic acid 2. To drive the equilibrium to the formation of isoamyl acetate we? Select one: a. removed isoamyl acetate b. removed the byproduct c. added excess sulfuric acid d. added excess isoamyl alcohol e. added excess acetic acid

Compare the IR spectra of the starting material (isoamyl alcohol) and the product (isoamyl acetate), focusing on identifying the absorption ranges and functional groups present in the peak regions. For instance, note the presence or absence of the OH stretching peak around cm(^-1).
