Preparation of ester via ion exchange resin Esters can be prepared by the reaction of a carboxylic acid with an alcohol in the presence of a catalyst such as concentrated sulfuric acid, hydrogen chloride, p-toluenesulfonic acid, or the acid form of an ion exchange resin: The most common esterification process is Fischer-Spier esterification, named after its creators. The advantages of using this particular esterification process is that is fairly simple to set up and recreate, as long as the proper acidic conditions are present. Both the overall reaction of Fischer esterification and the specific Fischer esterification reaction that was carried out in this lab is shown in figure 1.

Conclusion Purpose: The purpose of the experiment was to perform the acid-catalyzed Fischer Esterification of acetic acid and isopentyl alcohol to form isopentyl acetate, or banana oil, which is used in flavor industries. Stage 3: The intermediate is stabilized by the elimination of water. The reason is that oxygen has higher electronegativity compared to carbon. Course. To ensure the reaction is complete an acid catalyst is commonly used.
