Ethyl acetate (ETOAC, CAS No. 141-78-6) is one of the most important industrial organic solvents used globally in coatings, adhesives, inks, pharmaceuticals, electronics, and chemical manufacturing. It is a highly flammable, colorless liquid with a characteristic fruity odor. Its boiling point is approximately 77.1°C (170.8°F). The flash point is typically reported as -4°C (24.8°F) (closed cup), making it a highly volatile and flammable solvent.
For procurement engineers and chemical buyers, understanding key safety and physical parameters-especially the flash point and boiling point of ethyl acetate-is essential for proper storage, transportation, formulation design, and industrial process optimization.
Properties of Ethyl Acetate (ETOAC)
Boiling Point
The boiling point of Ethyl Acetate is 77.1°C (170.78°F). This property makes it a volatile solvent that evaporates quickly, which is why it is used in applications requiring rapid evaporation, such as in paints, coatings, and adhesives.
Flash Point
The flash point of Ethyl Acetate is −4°C (24.8°F). This low flash point is why Ethyl Acetate is highly flammable and should be handled with care, especially in environments where ignition sources are present.
Why the Boiling Point of Ethyl Acetate Matters in Industry?
At 77.1 °C, ethyl acetate boils just above room-temperature solvents like diethyl ether (34.6 °C) but well below heavier solvents like toluene (110.6 °C). This makes it ideal for processes that need a fast-evaporating solvent that is still easy to handle - coatings dry quickly, extractions concentrate efficiently, and residual solvent is easy to remove from finished products.
Industrial Applications of Ethyl Acetate (ETOAC CAS No. 141-78-6)
Coatings and Paint Industry
Ethyl acetate is widely used as a fast-drying solvent in automotive coatings, industrial paints, wood coatings, and surface finishing applications. Its low boiling point enables rapid evaporation, ensuring quick film formation and smooth surface quality.
Adhesives and Sealants
In adhesive production, ETOAC is used to improve viscosity control, enhance drying speed, and increase bonding efficiency. It is commonly applied in ethyl acetate-based adhesives and glue formulations.
Printing Ink Industry
Ethyl acetate is an important component in gravure printing inks, flexographic inks, and packaging ink systems.
Pharmaceutical and Chemical Synthesis
In the pharmaceutical industry, ethyl acetate is used as an extraction solvent, reaction medium, and purification solvent. Its relatively low toxicity and easy removal make it suitable for API intermediate processing.
Laboratory and Analytical Chemistry
ETOAC is widely used in HPLC sample preparation, liquid-liquid extraction, and organic synthesis reactions, making it a common solvent in laboratory and analytical chemistry applications.

Ethyl Acetate vs Butyl Acetate (Boiling Point Comparison)
| Solvent | Boiling Point | Evaporation Rate | Application |
|---|---|---|---|
| Ethyl Acetate | 77.1°C | Fast | Fast-drying coatings, inks |
| Butyl Acetate | 126°C | Medium | Automotive coatings, slower drying systems |
Ethyl acetate evaporates much faster than butyl acetate, making it suitable for high-speed production lines.
Ethyl Acetate vs Butyl Acetate (Flash Point Comparison)
| Property | Ethyl Acetate (ETOAC, CAS 141-78-6) | Butyl Acetate |
|---|---|---|
| Flash Point (Closed Cup) | -4°C (24.8°F) | ~22–27°C (71.6–80.6°F) |
| Flammability | Highly flammable | Flammable |
| Safety Level | Higher fire risk, stricter control required | Relatively lower risk compared to ethyl acetate |
Safety and Handling Considerations
Due to its low boiling point and high volatility, ethyl acetate(ETOAC) should be handled carefully:
- Store in cool, well-ventilated areas
- Keep away from ignition sources
- Use explosion-proof equipment in industrial settings
- Follow MSDS guidelines strictly
