Ethyl Acetate (CAS No. 141-78-6) has a melting point of approximately -83.6°C and a boiling point of approximately 77.1°C at standard atmospheric pressure. These properties make it a fast-evaporating, easy-handling solvent widely used in coatings, inks, adhesives, pharmaceuticals, and laboratory processing.
What Are the Exact Melting and Boiling Points of Ethyl Acetate?
Ethyl Acetate, also known as Ethyl Ethanoate, is one of the most commercially important ester solvents. Its thermal transition temperatures are essential for storage, handling, transportation, and formulation design.
Key physical data include:
- CAS Number: 141-78-6
- Molecular Formula: C₄H₈O₂
- Molecular Weight: 88.11 g/mol
- Melting Point: -83.6°C
- Boiling Point: 77.1°C (at 101.3 kPa / 1 atm)
- Flash Point: -4°C (closed cup, typical reference)
The very low melting point means Ethyl Acetate remains liquid under most industrial climate conditions. The moderate boiling point allows fast evaporation while still being manageable in closed processing systems.
This balance is one reason Ethyl Acetate is preferred over extremely volatile solvents such as acetone in many applications.

Why Does the Melting Point Matter in Industrial Use?
Many buyers focus only on boiling point, but melting point is equally important for logistics and cold-weather storage.
With a melting point of -83.6°C, Ethyl Acetate rarely freezes during normal transportation or warehouse conditions.
Practical Benefits:
- Remains liquid in refrigerated storage above -80°C
- Suitable for winter transport in most global climates
- Reduces risk of crystallization in pipelines or drums
- Easier pumping and unloading than higher-freezing solvents
Comparison Examples:
| Solvent | Approx. Melting Point |
|---|---|
| Ethyl Acetate | -83.6°C |
| Water | 0°C |
| Acetic Acid | 16.6°C |
Why Is the Boiling Point of EtOAc So Important for Manufacturing?
The boiling point of 77.1°C is one of the most commercially useful characteristics of Ethyl Acetate.
- Faster drying than Isopropyl Alcohol (82.5°C) in many systems
- Much slower than Acetone (56°C), giving better leveling
- Faster than Butyl Acetate (126°C), improving throughput
Production Advantages:
- Shorter coating drying cycles
- Reduced oven energy demand in some systems
- Better print line speed for packaging inks
- Efficient solvent recovery by distillation
For coatings and inks, this boiling point helps balance two competing needs: speed and surface quality.
