Fischer esterification mechanism practice
WebApr 6, 2024 · As the overall reaction is reversible, the Fischer Esterification Process must involve the continuous removal of water from the system or the use of a significant excess of alcohol. The process starts with the carboxylic acid protonation of the carbonyl group, which is then attacked by alcohol. 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 ...
