No, ethyl acetate is not completely miscible with water. but rather partially or slightly soluble, usually forming two layers.
What is Ethyl acetate Organic Solvent?
CAS 141-78-6 Ethyl acetate is a colorless liquid with a sweet odor. It is an organic compound formed by the combination of ethanol (an alcohol) and acetic acid. Ethyl Acetate(ETAC) solvent is widely used in coatings, pharmaceuticals, food processing, and chemical synthesis.

Solubility of Ethyl Acetate in Water
At room temperature (20–25°C):
- Solubility in water: ~8–10 g per 100 mL of water
- Water solubility in ethyl acetate: ~3%
Its solubility increases with increasing temperature. Furthermore, surfactants can reduce the surface tension of water, helping EtOAc to mix better with water, thereby improving its solubility. Due to the poor miscibility of ethyl acetate with water, it is primarily used in non-aqueous systems in practical applications.

Applications of Solvent ethyl acetate
Depending on the industry, manufacturers may use it for:
- Adhesives and glues
- Industrial and protective coatings
- Oil-based lacquers
- Fragrances
- Decaffeination of tea and coffee
- Cleaning formulas
- Petroleum products
- Fruit essences
- Food flavorings
- Cigarettes
- Medications
Perfumes, for example, may contain low-purity ethyl acetate. Some manufacturers use this compound to produce plastic films. Others add it to foods and beverages.

FAQ
What are the properties of Ethyl Acetate?
- Formula: Ethyl acetate (C₄H₈O₂) is an ester formed by esterification of ethanol and acetic acid. Its structure combines an ethyl group (C₂H₅) and an acetate group (COO).
- Boiling Point: 77.1°C (170.78°F). Volatile and fast-evaporating.
- Density: ~0.902 g/cm³ (20°C). Low density supports quick evaporation.
- Flash Point: −4°C (24.8°F). Highly flammable; requires careful handling.
- Solubility: Soluble in water, ethanol, ether and other organic solvents. Versatile for extraction and dissolution of various compounds.
Is Ethyl Acetate a Green Solvent?
Yes, CAS 141-78-6 Ethyl acetate is a green solvent because it breaks down easily and has a lower impact on the environment compared to other chemicals.
How should I store Ethyl Acetate?
Store it in a cool, dry place, away from heat and flames, to avoid any fire hazards.
