Methyl Acetate, chemically known as methyl ethanoate (CAS 79-20-9), is a fundamental organic ester with a broad spectrum of applications across numerous industries. Its combination of physical properties and chemical reactivity makes it a valuable solvent, intermediate, and component in various formulations. Understanding these characteristics is essential for professionals seeking to leverage its capabilities. As a prominent chemical supplier, we aim to provide comprehensive insights into Methyl Acetate's properties and uses.

Key Physical and Chemical Properties of Methyl Acetate

Methyl Acetate is a clear, colorless liquid with a distinctive sweet, fruity odor, often reminiscent of nail polish remover or glue. Its key properties include:

  • Molecular Formula: C₃H₆O₂
  • Molar Mass: Approximately 74.08 g/mol
  • Boiling Point: Around 57°C (135°F) at standard pressure. This low boiling point signifies its fast evaporation rate.
  • Melting Point: A very low melting point of approximately -98°C (-144°F).
  • Density: Around 0.93 g/cm³ at 20°C, making it less dense than water.
  • Solubility: Moderately soluble in water (~25% at 20°C) and miscible with most common organic solvents like ethanol and diethyl ether.
  • Flash Point: It is a highly flammable liquid with a low flash point (around -10°C or 14°F), requiring careful handling.
  • Odor Threshold: Possesses a low odor threshold, meaning its presence can be detected even at low concentrations.
  • Reactivity: As an ester, it can undergo hydrolysis in the presence of strong acids or bases, reverting to methanol and acetic acid. It is also susceptible to transesterification reactions.

Diverse Industrial Applications of Methyl Acetate

Methyl Acetate's versatile properties lend themselves to a wide range of applications:

  • Solvent in Coatings and Paints: Its excellent solvency for resins and fast evaporation rate make it ideal for automotive finishes, industrial coatings, wood lacquers, and varnishes, contributing to quick drying and smooth film formation.
  • Adhesives and Sealants: Used to dissolve polymers and control viscosity in various adhesive and sealant formulations.
  • Printing Inks: Essential for flexographic and gravure printing inks, facilitating rapid drying on substrates and maintaining print quality.
  • Nail Polish Removers: A common ingredient in nail polish removers due to its effectiveness in dissolving nitrocellulose and other polish components.
  • Chemical Intermediate: It serves as a precursor in the synthesis of other chemicals, such as acetic anhydride (through carbonylation) and various other esters via transesterification.
  • Extraction Solvent: Utilized in certain extraction processes in pharmaceuticals and food industries.
  • Cleaning Agents: Found in some industrial cleaning formulations for degreasing and surface preparation.

Safety and Handling Considerations

Given its flammability and potential health effects (primarily irritation and central nervous system depression at high concentrations), proper handling and storage are crucial. It should be stored in well-ventilated areas away from ignition sources and incompatible materials like strong oxidizers, acids, and bases. Always refer to the Safety Data Sheet (SDS) for detailed information on handling, personal protective equipment (PPE), and emergency procedures.
