Product Description

Product Description

Basic Information

• Chemical Formula: C7H9N
• Product Names: Methylaniline, N-Methyl benzenamine
• Appearance: Colorless to light yellow oily liquid (darkens on exposure to air/light)
• Odor: Mild, aromatic amine-like smell
• Solubility: Slightly soluble in water; miscible with organic solvents (e.g., ethanol, ether, benzene).

Physical and Chemical Properties

• Density: 0.989 g/cm³ (20°C)
• Melting Point: -57°C
• Boiling Point: 196-199°C
• Refractive Index: 1.568 (20°C)
• Flash Point: 78°C (closed cup)
• pKa (Conjugate Acid): ~4.58 (in water)

Chemical Properties

• Amine Reactivity:
  • As a secondary amine, it exhibits basic properties, forming salts with acids (e.g., hydrochloric acid to give N-methylanilinium chloride).
  • Prone to nucleophilic substitution reactions, especially at the amino group (e.g., acylation to form amides).
• Oxidation Sensitivity: Easily oxidized in air, leading to color darkening; can be oxidized by strong oxidants to form quinones or nitro compounds.
• Electrophilic Substitution: The amino group is a weak electron-donor, directing electrophilic substitution on the benzene ring to the ortho and para positions (though less activating than aniline due to methyl substitution).

A
pplications

• Chemical Synthesis:
  • Intermediate in Dyestuff Production: Used in the manufacture of azo dyes, triphenylmethane dyes, and other organic pigments.
  • Pharmaceutical Intermediate: For synthesizing drugs like local anesthetics, antimalarials, and antidepressants (e.g., intermediates for procaine).
  • Polymer Additive: As a curing agent or accelerator in epoxy resin systems; precursor for polyurethane modifiers.
• Rubber Industry:
  • Used as a vulcanization accelerator and antioxidant in rubber processing.
• Solvent and Reagent:
  • As a high-boiling solvent for organic reactions; reagent in the synthesis of heterocyclic compounds (e.g., indoles, quinolines).

Safety and Handling

• Hazard Class:
  • Toxic by ingestion, inhalation, and skin absorption (suspected carcinogen; IARC Group 3: not classifiable as to carcinogenicity in humans).
  • Causes severe skin and eye irritation; may damage blood cells (hemolytic effect) and liver.
• Storage:
  • Store in a cool, dark, well-ventilated place, sealed in airtight containers to prevent oxidation.
  • Keep away from oxidizing agents, acids, and light.
• Handling Precautions:
  • Use in a fume hood with proper ventilation; wear chemical-resistant gloves, goggles, and protective clothing.
  • Avoid skin contact (use barrier creams); if exposed, wash immediately with soap and water.
  • In case of spillage, contain with absorbents and dispose of as hazardous waste.

Environmental Impact

• Toxicity: Toxic to aquatic life (LC50 for fish ~1-10 mg/L); may bioaccumulate slightly.
• Degradation: Slowly biodegradable in water and soil; photodegradation in the atmosphere is possible.
• Regulations: Classified as a hazardous substance in many regions; strict emission and disposal controls apply.
