WebJul 1, 2024 · Fischer esterification regarded as the most common and widely practiced process of ester synthesis, faces serious limitations of low conversion and high reaction time attributed largely to ... WebThe Fischer esterification reaction takes advantage of Le Chatelier's principle to increase the amount of carboxylic acid that is esterified. The equilibrium is shifted towards products by using a large excess of the alcohol (it is used as the reaction solvent), and (in some cases) also removing water as it it formed.
