What Is Ethyl Acetate (EA) Solvent ?
Ethyl acetate (EA) solvent is a colorless, transparent, flammable liquid with a fruity aroma. Ethyl acetate is low in toxicity, highly volatile, with a relative density of 0.902, a melting point of 83 ℃, a boiling point of 77.1°C, and is slightly soluble in water but soluble in most organic solvents such as alcohols, ketones, ethers, and chloroform.
Boiling Point of Ethyl Acetate
The boiling point of ethyl acetate (EA solvent) is 77.1°C (170.8°F) at standard atmospheric pressure (1 atm).
Due to its relatively low boiling point, ethyl acetate is considered a fast-evaporating organic solvent, making it highly suitable for applications that require quick drying and efficient processing.

Why Does Ethyl Acetate Have a Low Boiling Point?
The low boiling point of ethyl acetate is mainly determined by its molecular structure and intermolecular forces.
Molecular Structure of Ethyl Acetate
Ethyl acetate (chemical formula: C₄H₈O₂) is an ester formed from ethanol and acetic acid. It contains:
- A polar ester functional group
- A non-polar ethyl group
This balanced polarity contributes to moderate intermolecular attraction.
Intermolecular Forces and Volatility
Compared to alcohols like ethanol, ethyl acetate cannot form strong hydrogen bonds with itself. As a result:
- Lower intermolecular forces
- Higher volatility
- Lower boiling point
Comparison with Other Solvents
- Ethyl acetate: 77.1°C
- Ethanol: 78.4°C
- Acetone: 56°C
This places ethyl acetate in the ideal range for controlled evaporation.
physical properties of ethyl acetate (EA)
| Property | Value |
|---|---|
| Boiling Point | 77.1°C |
| Density (20°C) | 0.897 g/cm³ |
| Flash Point | -4°C |
| Vapor Pressure | Moderate |
