Fischer esterification mechanism practice
WebFischer esterification is a special type of esterification and the process of forming an ester by refluxing a carboxylic acid and an alcohol in the presence of an acid catalyst. Most carboxylic acids are suitable for the reaction, but the alcohol should generally be a primary or secondary alkyl. Tertiary alcohols are prone to elimination, and ... WebNov 14, 2012 · Esterification is a straightforward reaction that utilizes several key techniques in synthetic organic chemistry. One direct approach, known as the Fischer esterification reaction, involves the acid-catalyzed condensation of an alcohol and a carboxylic acid, yielding an ester and water. Esters can also be formed by the reaction of …
