Ethyl acetate is an organic compound with the formula CH₃COOCH₂CH₃. It is a colorless liquid with a characteristic sweet smell and is widely used as a solvent in various applications due to its low toxicity and pleasant odor.
🏭⚗️ Production
Ethyl acetate is typically produced by the esterification of ethanol and acetic acid in the presence of an acid catalyst, such as sulfuric acid. Industrially, it is often manufactured by catalytic carbonylation of ethanol or by the reaction of ethylene with acetic acid.
🔬 Properties
Ethyl acetate is a volatile, colorless liquid with a boiling point of about 77 °C. It is moderately soluble in water and miscible with most organic solvents. It has a sweet, fruity odor. It acts as a solvent due to its ability to dissolve a wide range of chemical compounds and evaporates quickly under normal conditions.
🧪 Applications
• Used as a solvent in paints, coatings, adhesives, and nail polish removers.
• Employed in the manufacture of pharmaceuticals and synthetic flavors.
• Used as an extraction solvent in laboratories and in the food industry.
• Applied in the production of perfumes and cosmetics.
