Fischer Esterification

A typical procedure to synthesize esters is the Fischer esterification wherein a carboxylic acid is treated with an alcohol in the presence of a mineral inorganic acid catalyst In this experiment lauric acid (dodecanoic acid) is converted to ethyl laureate Lauric acid is representative of a class of molecules called fatty acids

What factors affect the reaction chemistry of esterification?
There are several factors that affect the reaction chemistry of esterification. Structure of a molecule and types of functional groups or substitutes associated with carboxylic acids and alcohols determine the speed at which both reagents are esterified as well as the extent of equilibrium.
What are the limitations of Fischer esterification?
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 establishment of equilibrium. Ester hydrolysis, reverse reaction to esterification, starts by supply of a byproduct- water.
What is a Fisher esterification reaction?
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.
