WebThe most used organic solvents are ethyl acetate and butyl acetate. These are chemically called esters. Esters are shaped by the condensation reaction between alcohol and carboxylic acid. This is known as esterification. In a condensation reaction, two molecules join and produce a bigger molecule while disposing of a little molecule. WebJan 8, 2024 · Therefore, special methods are being used for the synthesis of esters by using tertiary alcohols. Acid-catalyzed Fischer esterification. The most common example of acid catalyst fisher esterification is as follows: Mechanism of acid-catalyzed Fischer esterification. The mechanism of Fischer esterification is similar to acid-catalyzed reactions.
