# propyl ethanoate synthesis

The water comes from the dilute acid, and so you would mix the ester with an excess of dilute acid. The reaction is catalysed by dilute acid, and so the ester is heated under reflux with a dilute acid like dilute hydrochloric acid or dilute sulphuric acid.

Propyl acetate, also known as propyl ethanoate, is a chemical compound used as a solvent and an example of an ester.

. I know that the final step has to be condensation, since that's how you make esters. These are picked up by the ethanoate ions (or propanoate ions or whatever) present in the salts to make ethanoic acid (or propanoic acid, etc).
