Ethyl acetate is a versatile solvent that can dissolve many substances, making it an essential component in the production of many products. In this article, we will discuss the chemical properties of ethyl acetate, its synthesis, uses, safety measures, and environmental impact.

2. Chemical Properties of Ethyl Acetate

Molecular Formula and Weight

The molecular formula of ethyl acetate is C4H8O2, and its molecular weight is 88.11 g/mol.

Boiling and Melting Point

The boiling point of ethyl acetate is 77.1 °C, and its melting point is -83.6 °C.

Solubility

Ethyl acetate is soluble in water, ethanol, and many other organic solvents.

Odor

Ethyl acetate has a sweet, fruity odor that is similar to pears or apples.

3. Synthesis of Ethyl Acetate

Ethyl acetate is synthesized through the reaction of ethanol and acetic acid. The reaction is catalyzed by sulfuric acid and produces ethyl acetate and water.

CH3COOH + C2H5OH ⇌ CH3COOC2H5 + H2O

This reaction is an example of an esterification reaction, which involves the reaction between an alcohol and a carboxylic acid to produce an ester and water.
