WebNov 25, 2024 · Typical Fisher esterification reaction involves heating a mixture of carboxylic acids and an excess amount of corresponding alcohols in the presence of a catalyst as shown in Eq. (1). The reaction achieves equilibrium after a certain time -- governed by process kinetics and thermodynamics. The primary advantages of Fischer esterification compared to other esterification processes are based on its relative simplicity. Straightforward acidic conditions can be used if acid-sensitive functional groups are not an issue; sulfuric acid can be used; weaker acids can be used with a tradeoff of longer reaction times. Because the reagents used are "direct," there is less environmental impact in terms of waste products and harmfulness of the reagents. Alkyl halide…
