Propyl acetate, also known as propyl ethanoate, is a chemical compound used as a solvent. 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, often via Fischer–Speier esterification.Propyl acetate is made by reacting propanol with ethanoic acid.chemicals like propyl acetate are also known as esters.The reaction by which propyl acetate is formed is known as a condenstaion reaction ,this reaction uses sulfuric acid as a catalyst and produces water as a byproduct.
