Introduction to Ethyl Acetate (EtOAc)
Ethyl acetate (EtOAc) is a widely used organic solvent in industrial manufacturing. It is valued for its fast evaporation rate, strong solvency, and relatively low toxicity, making it suitable for applications such as coatings, inks, adhesives, and pharmaceuticals.
What Is the Boiling Point of Ethyl Acetate (EtOAc)?
The boiling point of ethyl acetate is 77.1°C (170.8°F) at standard atmospheric pressure (1 atm).
This moderate boiling point makes ethyl acetate a fast-drying solvent, widely preferred in industries where controlled evaporation is required.

Chemical Properties of Ethyl Acetate
- Hydrolysis: Ethyl acetate gives ethanol and acetic acid on reaction with water.
- Condensation: Ethyl acetate shows Claisen condensation reaction and produces ethyl acetoacetate.
2CH3CO2C2H5 (ethyl Acetate) + NaOCH2CH3/H3O+ ⇢ C6H10O3 (Ethyl acetoacetate) +C2H5OH (ethanol)
- Reaction with Sodium Hydroxide: When ethyl acetate or ethyl ethanoate reacts with sodium hydroxide then it gives sodium acetate and ethanol.
CH3CO2C2H5 + NaOH -----> C2H5OH + CH3CO2Na
It is highly flammable and generally found in alcoholic drinks like wines and also used as an organic solvent in paints, cellulose, rubber, etc.
