Introduction

Propyl acetate, also known as propyl ethanoate, is a chemical compound used as a solvent and an example of an ester. This clear, colorless liquid is known by its characteristic odor of pears. Due to this fact, it is commonly used in fragrances and as a flavor additive. It is formed by the esterification of acetic acid and 1-propanol (known as a condensation reaction), often via Fischer–Speier esterification, with sulfuric acid as a catalyst and water produced as a byproduct.
