Ethyl acetate is a colorless, transparent liquid with low toxicity and sweet taste. When the concentration is high, it has a pungent odor, is volatile, sensitive to air, and can absorb water, causing it to slowly hydrolyze and become acidic. Compatible with chloroform, ethanol, acetone and ether, soluble in water (10% ml/ml). Can dissolve certain metal salts (such as lithium chloride, cobalt chloride, zinc chloride, iron chloride, etc.) reaction. Relative density 0.902. Melting point -83°C. The boiling point is 77 °C. The refractive index is 1.3719. Flash point 7.2 °C (open cup). Flammable. Vapors can form explosive mixtures with air. The median lethal dose (rat, oral) was 11.3 ml/kg.
