E Experimental Background Esterification is a common type of organic chemical reaction It is the reaction between alcohol and carboxylic acid or oxygen-containing inorganic acid to form ester and water The esterification reaction between carboxylic acid and alcohol is reversible, and the reaction is generally very slow Therefore concentrated sulfuric acid is often used as a catalyst, and the operation with water can be used to promote the reaction processExperimental Background Esterification is a common type of organic chemical reaction.
