What is the boiling point of ethyl acetate?
77°C
Ethyl acetate (CAS 141-78-6) possesses unique physical properties. It is a colorless, transparent liquid with a strong fruity aroma, which is one reason it is commonly used as a food flavoring. It has a relatively low boiling point of approximately 77°C, a melting point of -83.6°C, and a density lower than water, at about 0.902 g/cm³. Ethyl acetate is slightly soluble in water and is miscible in any proportion with various organic solvents such as ethanol, diethyl ether, and chloroform. This property makes it an excellent solvent.

ethyl acetate industrial uses
Ethyl acetate (CAS 141-78-6) has a wide range of applications.
- In the food industry, it is a legal food additive used as a flavoring agent and solvent. Due to its fruity aroma, it is commonly added to beverages, candies, pastries, and other foods to enhance flavor. It also serves as a solvent and diluent for edible flavorings, helping them disperse and stabilize more effectively.
- In the coatings and ink industries, ethyl acetate serves as a vital solvent. Its excellent solubility and volatility enable it to dissolve film-forming substances like resins and oils. It evaporates rapidly during the drying process, accelerating coating drying times and improving coating performance. Consequently, it is widely used in the production of nitrocellulose lacquers, acrylic paints, inks, and similar products.
- The pharmaceutical sector is another major application area for ethyl acetate. It serves as a solvent and extractant for drugs, used in drug synthesis to extract active ingredients or dissolve pharmaceutical substances. Additionally, in certain topical formulations, ethyl acetate functions as both a solvent and a penetration enhancer, facilitating better absorption of drugs through the skin.
- In personal care products, ethyl acetate 141 78 6 is commonly used in the production of perfumes and cosmetics. It dissolves fragrances and other active ingredients while possessing a pleasant aroma, enhancing the user experience of these products. Its volatility also facilitates the release of scents in perfumes and similar products.
