Ethyl acetate chemical and physical properties
- Physical properties: Ethyl acetate has a boiling point of 77.1°C, a density of 0.902 g/cm³, is slightly soluble in water (solubility of approximately 8.3 g/100 mL at 20°C), but readily soluble in organic solvents such as ethanol and ether. Its low toxicity and rapid volatility make it an ideal solvent for paints and adhesives.
- Chemical properties: Ethyl acetate readily undergoes hydrolysis, producing acetic acid and ethanol under acidic or alkaline conditions. In addition, it can participate in reactions such as transesterification and reduction, and is an important intermediate in the synthesis of pharmaceuticals and dyes.
