What Is Methyl Acetate?
Methyl acetate, also known as acetic acid methyl ester, is an organic ester containing a heteroatom functional group.
- Molecular formula: C₃H₆O₂
- Molecular weight: 74.08
- Appearance & Odor
- Colorless, transparent liquid
- Volatile with a characteristic aromatic odor
Physical Properties
- Melting point: −81°C
- Boiling point: 52–54°C
- Flash point: −19°C
- Density: 0.921 g/mL
- Readily soluble in water
- Miscible with organic solvents such as ethanol and diethyl ether
Chemical Properties
- Flammability: Flash point -10°C, explosive limits 3.1%–16.0% (by volume). Vapors form explosive mixtures with air.
- Hydrolysis: Hydrolyzes in vivo to form methanol, which is further metabolized into formaldehyde and formic acid.
- Reactivity: Decomposes upon UV irradiation into CO₂, H₂, and CO; reacts with thorium oxide at high temperatures to produce acetone and other products.
methyl acetate uses in industry
- Organic Solvent: Due to its excellent solubility, methyl acetate (MeOAc) is widely used as an organic solvent in coatings, inks, adhesives, and cleaning agents.
- Resin and Coating Production: In resin and coating manufacturing, MeOAc serves as a key raw material that enhances product properties such as coating film hardness and abrasion resistance.
- Fragrance Manufacturing: Possessing a distinctive aroma, methyl acetate is also employed in the food and perfume industries as a fragrance component to impart unique scents to products.
- Chemical Synthesis: Additionally, methyl acetate serves as an intermediate in producing other chemicals, including certain plastics, pharmaceuticals, and dyes.
- Extraction Agent: In chemical extraction processes, methyl acetate (MeOAc) can be used to extract oils and other useful compounds from plant and animal materials.
