Did you know?
Fischer esterification or Fischer–Speier esterification is a special type of esterification by refluxing a carboxylic acid and an alcohol in the presence of an acid catalyst. The reaction was first described by Emil Fischer and Arthur Speier in 1895. Most carboxylic acids are suitable for the reaction, but the alcohol should generally be primary or secondary. Tertiary alcohols are prone to elimination. … WebJun 29, 2024 · Concentrated sulfuric acid is often used as a catalyst in Fischer esterification reactions. To my knowledge, the role it plays in the reaction is not as a reducing agent or dehydrating agent but only serves the role of creating an acidic environment, as seen in the mechanism. Thus, dilute sulfuric acid would be sufficient.
WebFischer Esterification is the name given to the acid-catalysed reaction between an alkanoic acid (carboxylic acid) and an alkanol (alcohol) (3) . Synthesis or preparation of esters in the laboratory involves 3 steps: … WebThe mechanism of Fischer Esterification is an example of nucleophilic addition-elimination and the overall result of it is the replacement of the OH group by the OR. In general, it is a slow reaction carried out in reflux …
