Essentially, we are drawing the reverse order of Fischer esterification so, in the first step the ester is protonated promoting the nucleophilic attack of water: Notice that just like the Fischer esterification, the process is an equilibrium which makes the reaction a little challenging as it may require higher temperatures and removal of the alcohol as it is formed to push the equilibrium forward. 0000001303 00000 n Remember, soap is a salt of a fatty acid and can be formed when a fat (an ester derived from a glycerol and three molecules of fatty acid) is hydrolyzed by base catalysis: How do we know this is the correct mechanism of base-catalyzed ester hydrolysis?
