Esterification

Esterification is a chemical reaction where an acid, usually a carboxylic acid, reacts with an alcohol to form an ester and water. This process often occurs with the help of an acid catalyst and is common in making fragrances, flavors, and plastics. During the reaction, the acid's carboxyl group combines with the alcohol's hydroxyl group, creating a new compound called an ester. Esters typically have distinctive fragrances and are used in a variety of industrial and consumer products. The reaction is reversible, meaning esters can be broken back down into their original acid and alcohol under certain conditions.
