Ethyl acetate, also known as ethyl acetate. Is a colorless transparent flammable liquid with fruit aroma. Low toxicity. Volatile. Relative density 0.902. Melting point - 83 ℃. The boiling point of 77 ℃. Refractive index 1.3719. Flash point 7.2℃ (open cup). Slightly soluble in water, soluble in alcohol, ketone, ether, chloroform and other organic solvents.

Pure ethyl acetate has a pungent odor, is sensitive to air, and can absorb water, making it hydrolyze slowly and become acidic. Can dissolve some metal salts (such as lithium chloride, cobalt chloride, zinc chloride, ferric chloride, etc.). Its steam and air can form an explosive mixture, meet open fire, high heat energy caused combustion explosion.
