Acid Catalyst Comparison in Fischer Esterification Reactions

Fischer esterification is a method of producing an ester from a carboxylic acid and an alcohol in the presence of an acid catalyst. The Fischer esterification mechanism is well known and includes several reversible steps. Conditions that favor product formation include a large excess of the alcohol and/or the removal of water as a product of the esterification reaction. In this work, different acid catalysts are examined, with an emphasis on hydrochloric acid, sulfuric acid, and dried Dowex H+ cation-exchange, a resin that has been recently reported as a green approach because it is non-toxic and reusable. Dowex ion exchange resins are polymers able to switch ions from a solution to ions on the surface of the resin. Analysis of ester products from a variety of carboxylic acids and alcohols is performed using gas chromatography and IR spectroscopy.
