Storage precautions: Store in a cool and ventilated warehouse. Stay away from sources of fire and heat. The storage temperature should not exceed 37 ℃. Keep the container sealed. It should be stored separately from oxidants, acids, and bases, and avoid mixing storage. Adopt explosion-proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that are prone to generating sparks. The storage area should be equipped with emergency response equipment for leaks and suitable containment materials.

1. Colorless and transparent liquid. Can be miscible with chloroform, alcohol, acetone, and ether; At 25 ℃, 1ml of this product is soluble in 10ml of water. As the temperature increases, a binary azeotropic mixture is formed. The boiling point of the azeotropic mixture formed with water is 70.4 ℃, with a water content of 6.1% by mass; The boiling point of the azeotropic mixture formed with ethanol is 71.8 ℃; The boiling point of the ternary azeotropic mixture formed with 7.8% water and 9.0% ethanol is 70.2 ℃. Volatile and prone to ignition. It has a fruity aroma. Moisture can cause it to slowly decompose and undergo acidic reactions. Flammable, its vapor can easily form explosive mixtures with air, with an explosive limit of 2.2% to 11.2% by volume.

2. Chemical properties: Ethyl acetate is easily hydrolyzed, and when water is present at room temperature, it gradually hydrolyzes to produce acetic acid and ethanol. Adding trace amounts of acid or base can promote hydrolysis reactions. Ethyl acetate can also undergo common ester reactions such as alcoholysis, ammonolysis, ester exchange, and reduction. In the presence of metallic sodium, it self condenses to form 3-hydroxy-2-butanone or ethyl acetoacetate; Reacts with Grignard reagent to produce ketones, which further react to obtain tertiary alcohols. Ethyl acetate is relatively stable to heat and remains unchanged after heating at 290 ℃ for 8-10 hours. When passing through red hot iron pipes, it decomposes into ethylene and acetic acid. When heated to 300-350 ℃, zinc powder decomposes into hydrogen, carbon monoxide, carbon dioxide, acetone, and ethylene. When dehydrated at 360 ℃, aluminum oxide can decompose into water, ethylene, carbon dioxide, and acetone. Ethyl acetate decomposes under ultraviolet radiation to produce 55% carbon monoxide, 14% carbon dioxide, and 31% flammable gases such as hydrogen or methane. Reacts with ozone to produce acetaldehyde and acetic acid. Gaseous hydrogen halides react with ethyl acetate to produce haloethane and acetic acid. Among them, hydrogen iodide is the most reactive, while hydrogen chloride needs to be pressurized at room temperature to decompose. It is heated together with phosphorus pentachloride to 150 ℃ to produce chloroethane and acetyl chloride. Ethyl acetate forms various crystalline complexes with metal salts. These complexes are soluble in anhydrous ethanol but insoluble in ethyl acetate, and are easily hydrolyzed when in contact with water.
