WebNov 14, 2012 · The Fischer esterification is an equilibrium reaction whereas other esterification routes do not involve an equilibrium. To shift the equilibrium to favor the production of esters, it is customary to use an excess of one of the reactants, either the alcohol or the acid. WebThe Fisher esterification is a staple of many undergraduate organic laboratory courses due to its synthetic utility and its relevance to course materials. Moreover, it is a reaction that typically does not require extremely hazardous chemicals and long reaction times [ 6].
