Ethyl acetate is a colorless, transparent liquid with low toxicity. It has a sweet taste, but at higher concentrations, it has a pungent odor. It is volatile, sensitive to air, and absorbs moisture, causing it to slowly hydrolyze and become acidic. It is miscible with chloroform, ethanol, acetone, and ether, and soluble in water (10% ml/ml). It can dissolve certain metal salts (such as lithium chloride, cobalt chloride, zinc chloride, and ferric chloride). Its relative density is 0.902. Its melting point is -83℃. Its boiling point is 77℃. Its refractive index is 1.3719. Its flash point is 7.2℃ (open cup). It is flammable. Its vapor can form explosive mixtures with air.
