Fischer Esterification is a reaction between a carboxylic acid and an alcohol to form an ester. Refluxing the two reactants with an acid catalyst forms the ester. Fischer Esterification was discovered in 1895 by the German chemist‚ Emily Fischer and Arthur Speier. The reaction is also sometimes known as Fischer-Speier Esterification. The major components of almost all natural flavors and odors are esters. These fragrant esters are formed by the Fischer Esterification reaction. Saponification

Barry Allahyar Dr. Dodd CHEM 2122 2010-09-16 Experiment 19: Fischer Esterification‚ Conclusion The objective in this experiment was to efficiently perform an Fischer esterification of 1-butanol and acetic acid to form water and n-butyl acetate‚ and to confirm the esterification using IR spectroscopy analysis. It was found that 0.734 grams of n-butyl acetate was formed with a percent yield of 61%. The product was confirmed using IR spectroscopy and boiling point confirmation. The reaction mechanism

2. Preparation of ester via ion exchange resin The Lewis or Brønsted Acid – Catalyzed esterification is also know as Fischer Esterification which a carboxylic acid reacts with an alcohol to yield an ester; typically in equilibrium. The position of equilibrium can be influenced or shifted by adding more of the acid or alcohol depending on the intended direction. The Fischer Esterification mechanism involves a series of completely reversible steps: an initial protonation of the carboxyl group‚
