Is ethyl acetate (cas 141-78-6) different from acetone (cas 67-64-1)?
Yes, ethyl acetate and acetone are very different chemicals.
what is ethyl acetate (cas 141-78-6)?
Ethyl acetate (EtOAc) is a colourless liquid with a fruity odour, which is very commonly used as a solvent in paints, varnishes, adhesives, and pharmaceuticals. It evaporates quite quickly and is useful for its low toxicity and biodegradability.
- Melting Point: -83.6°C
- Boiling Point: 77.1°C
- Specific Gravity: 0.8945
- Vapour Density: 3
- Flashpoint: -3°C
what is acetone (cas 67-64-1)?
Acetone is a strong and fast-evaporating solvent which is known for its high solvency power. It is widely used in cosmetics (especially nail polish remover), cleaning agents, and chemical manufacturing. Acetone is also a common intermediate in the production of plastics and synthetic fibres.
- Melting Point: -94°C
- Boiling Point: 56.5°C
- Relative vapour density: 0.788
- Flash point: -18°C
What is the difference between ethyl acetate and acetone?
| Feature | Acetone | Ethyl Acetate |
|---|---|---|
| Chemical Type | Ketone (C=O) | Ester (COO) |
| Odor | Strong, pungent | Mild, fruity, sweet |
| Polarity | More polar | Less polar |
| Solvency | Stronger, dissolves plastics/grease well | Good for resins, polymers, polymers |
| Volatility/Drying | High (faster evaporation) | Moderate (slower evaporation) |
| Applications | Nail polish remover, cleaning, degreaser | Coatings, glues, paints, pharmaceuticals |
| Toxicity/Harshness | Harsher on skin, more drying | Gentler alternative |
