Esters can be prepared by this method in the presence of an acid catalyst To force the reaction The molecular weight and theoretical yield of the product 5

This reaction, termed Fischer esterification in honor of its discoverer, can be used to product obtained (i e the yield) will be measured and the percent yield

[PDF] Synthesis of an Ester: Fischer Esterification The ester is synthesised

The carboxylic acid is the limiting reagent Using acetic acid? ⇒ The alcohol is the limiting reagent Weigh compounds directly into the reaction flask Be careful

[PDF] Fischer Esterification

A typical procedure to synthesize esters is the Fischer esterification, wherein a carboxylic Loss of water yields a carbocation stabilized by resonance, which need only lose a proton to give the desired ester Calculate the percent yield 2

[PDF] Esters An Introduction

For esters in which the alcohol and carboxylic acid are sterically unhindered, a 1:1 mixture of alcohol and carboxylic acid will yield an equilibrium mixture that is about 70 ester This means that if ester were isolated from this mixture, at best a 70 yield would be obtained
