Ethyl Acetate (CAS 141-78-6) is a medium-volatile ester solvent with a melting point of -83.6°C, boiling point of 77.1°C, and density of 0.897 g/cm³ (20°C). These properties define its fast evaporation, excellent solvency, and wide industrial use in coatings, inks, adhesives, and laboratories.
What Are the Key Physical Properties of Ethyl Acetate?
Ethyl acetate, with the chemical formula C₄H₈O₂, is an ester compound formed through the esterification of acetic acid and ethanol. At room temperature, it appears as a colorless and transparent liquid with a distinctive fruity aroma (similar to pear or apple scent), which makes it widely used as a food flavoring ingredient and fragrance solvent.
Its key physical properties include a boiling point of 77.1°C, a melting point of -83.6°C, a density of 0.902 g/cm³ (20°C), and a refractive index of 1.3720 (20°C). In terms of solubility, ethyl acetate is slightly soluble in water (approximately 8.3 g/L at 20°C) but is miscible with most organic solvents such as ethanol, ether, acetone, and benzene. It can also form binary or ternary azeotropic mixtures with water and ethanol, with azeotropic temperatures slightly lower than its pure boiling point.
Why Does the Boiling Point of EtOAc Matter in Industrial Applications?
The boiling point of Ethyl Acetate at 77.1°C is one of the most critical parameters determining its industrial performance.
Key Implications:
- Enables fast evaporation at room temperature and mild heating conditions
- Supports rapid drying in coatings and ink systems
- Improves production efficiency in high-speed manufacturing lines
- Allows controlled evaporation compared with ultra-volatile solvents
Comparative Perspective:
| Solvent | Boiling Point |
|---|---|
| Acetone | 56.0°C |
| Ethyl Acetate | 77.1°C |
| Ethanol | 78.3°C |
| Butyl Acetate | 126.0°C |
How Does the Melting Point of EtOAc Affect Storage and Logistics?
Ethyl Acetate (EtOAc) has a very low melting point of -83.6°C, which plays a major role in transportation and storage stability.
Key Practical Effects:
- Remains liquid under extreme cold conditions
- Prevents solidification in winter logistics systems
- Ensures stable pumping and transfer performance
- Reduces risk of crystallization in storage tanks
Supporting Data:
- Melting Point: -83.6°C
- Freezing risk zone: practically negligible under normal industrial conditions
- Operational temperature range: -50°C to +40°C typical safe handling
This makes Ethyl Acetate highly reliable for global supply chains, especially in regions with extreme seasonal temperature variations.
