Description

Carboxylic acid esters are often very aromatic compounds. They are the products of an esterification in which carboxylic acids react with alcohols with the elimination of a water molecule. In this experiment, the students themselves make 2 esters from propanoic acid (propionic acid), which are known for their aromatic smell. The students realise that aromas can be created from bad-smelling substances through a reaction. At the same time, they learn about an acid-catalysed reaction with esterification.
