PPT-Ester Lab

Preparation of Esters Lab Esters are responsible for the fruity odours and flavours of many naturally occurring products Chemists can reproduce these odours or flavours in the lab by mixing the right alcohol and carboxylic acid together thus producing artificial or synthetic versions of these naturally occurring compounds.
