What Is Ethyl Acetate Chemical Solubility In Water? - CAS No 141-78-6

Ethyl acetate (CAS No 141-78-6) is a moderately water-soluble organic solvent that directly affects its industrial performance in paints, coatings and other formulations.

Ethyl acetate (EtOAc) is a colorless, fruity-scented ester widely used as a fast-evaporating, versatile solvent.

has a slight solubility in water, with a solubility of approximately 8.3 g/100 mL (8.3% w/w) at 20℃. It is characterized as slightly soluble in water, but it can dissolve up to 3% water at room temperature. Its solubility increases at higher temperatures and it is highly soluble in common organic solvents.

The chemical structure of ethyl acetate determines its limited solubility in water.

• Polar ester groups can form weak hydrogen bonds with water molecules, thus allowing ethyl acetate to dissolve to some extent in water.
• Nonpolar alkyl chains repel water molecules. This hydrophobic effect prevents complete miscibility between the solvent and water.
• Ethyl acetate does not contain hydroxyl groups. Due to the lack of hydrogen bond donors, it cannot bind tightly to water, which keeps its solubility at a moderate level.

• Inhalation can cause dizziness and irritation.
• Prolonged exposure may affect the respiratory and nervous systems.

• Store in cool, ventilated areas away from heat and flames.
• Use proper personal protective equipment (PPE) during handling.
