Description and Uses
Propyl acetate, also known as propyl ethanoate, is an organic compound with a molecular formula of C5H10O2. It is a clear and colourless liquid with with a mild fruity odor. It is highly flammable with a flash point of 14°C and a flammability rating of 3. It is highly miscible with all common organic solvents (alcohols, ketones, glycols, esters) but has only slight miscibility in water. Propyl acetate is found in apple and formed by the esterification of acetic acid and 1-propanol (known as acondensation reaction), often via Fischer–Speier esterification, with sulfuric acid as a catalyst and water produced as a byproduct. It is primarily intended as a solvent in the coatings and printing inks industries. It is widely used in fragrances and as a flavor additive due to its odor. It also acts as a good solvent for cellulose nitrate, acrylates, alkyd resins, rosin, plasticizers, waxes, oils and fats.
n-Propyl acetate is used as a solvent for cellulose derivatives, plastics, and resins; in flavors and perfumes; and in organic synthesis.
