Ethyl acetate molecular weight: 88.105.

Ethyl acetate, also known as ethyl acetate, is an organic compound with the chemical formula C4H8O2. It is an ester with a functional group -COOR (a double bond between carbon and oxygen ), can occur common ester synergistic reactions such as alcoholysis, ammonolysis, transesterification, reduction, etc.

Ethyl acetate can undergo alcoholysis, ammonolysis, transesterification, reduction and other general ester synergy reactions. It self-condenses in the presence of metallic sodium to generate 3-hydroxy-2-butanone or ethyl acetoacetate; reacts with Grignard reagent to generate ketones, and further reacts to obtain tertiary alcohols. Chemical formula: C4H8O2. Molecular weight: 88.105.

Chemical properties of ethyl acetate

Ethyl acetate is relatively stable to heat and does not change when heated at 290°C for 8 to 10 hours. It decomposes into ethylene and acetic acid when passing through a red-hot iron pipe. Zinc powder heated to 300~350℃ decomposes into hydrogen, carbon monoxide, carbon dioxide, acetone and ethylene. Alumina dehydrated at 360℃ can decompose into water, ethylene and carbon dioxide. and acetone. Ethyl acetate decomposes under ultraviolet irradiation to produce 55% carbon monoxide.

Ethyl acetate is easily hydrolyzed and will gradually hydrolyze into acetic acid and ethanol in the presence of water at room temperature. Adding trace amounts of acid or alkali can promote the hydrolysis reaction. The biggest difference between alkaline hydrolysis and acidic hydrolysis of ethyl acetate is that alkaline hydrolysis is irreversible, that is, reversible and irreversible processes in the reaction mechanism. The reversible reaction of acetic acid with ethanol produces ethyl acetate.
