What is the structure of ethyl acetate liquid (CAS141-78-6)？

Ethyl Acetate (EA, CAS No. 141-78-6) is a colorless, volatile liquid widely used as an industrial solvent in coatings, inks, adhesives, pharmaceuticals, and chemical manufacturing.

Chemical Structure of Ethyl Acetate

Ethyl acetate is an ester formed from ethanol and acetic acid.

• Molecular formula: C₄H₈O₂
• Structural formula: CH₃–COO–CH₂–CH₃
• Functional group: Ester (–COO–)

The molecule consists of an acetate group (CH₃–COO–) linked to an ethyl group (–CH₂–CH₃). This simple ester structure is the foundation of ethyl acetate's solvency, volatility, and compatibility with many industrial materials.

Physical Properties of Ethyl Acetate Liquid (CAS: 141-78-6)

• Appearance: Ethyl Acetate is a colorless, transparent liquid with a strong odor.
• Melting and Boiling Points: Its melting point is -83.6℃ and its boiling point is 77.1℃, classifying it as a low-boiling-point liquid.
• Density: The density is 0.894 g/cm³.
• Solubility: Ethyl Acetate is not readily soluble in water, but it can dissolve many organic substances, such as fats, lipids, resins, paints, and solvents.
