Product Description

Product Description

Basic Information

• Chemical Name: 4,4'-Diaminodiphenylmethane
• Common Alias: Methylenedianiline (MDA)
• Molecular Formula: C13H14N2
• Molecular Weight: 198.27 g/mol
• CAS Number: 101-77-9

Physical and Chemical Properties

• Appearance:
  • At room temperature: White to light yellow crystalline solid (may darken upon exposure to air).
  • Pure form: Colorless crystals.
• Melting Point: 89-91°C
• Boiling Point: 398-401°C (at atmospheric pressure)
• Solubility:
  • Slightly soluble in water (0.1 g/100 mL at 25°C).
  • Soluble in organic solvents: ethanol, ether, benzene, acetone.
• Chemical Stability:
  • Stable under normal conditions but susceptible to oxidation in air, leading to color darkening.
  • Reacts with acids, acid chlorides, and anhydrides; forms salts with strong acids.

Applications

1. Polymer Industry
   • Epoxy Resins: Cures epoxy resins, forming high-strength, heat-resistant composites for coatings, adhesives, and electrical insulation.
   • Polyurethanes: Precursor for MDI (4,4'-diphenylmethane diisocyanate), a key component in polyurethane foams, elastomers, and plastics.
   • Polyamides: Synthesizes polyamides (nylons) with improved mechanical properties.
2. Chemical Intermediates
   • Manufactures dyes, antioxidants, and agricultural chemicals (e.g., herbicides, fungicides).
   • Precursor for Schiff bases and other nitrogen-containing organic compounds.
3. Research and Development
   • Used in laboratory syntheses and as a standard for analytical methods (e.g., HPLC, GC).

Safety and Toxicity

• Health Hazards:
  • Carcinogenicity: Classified as a probable human carcinogen (Group 2B, IARC) due to links with bladder and lung cancers.
  • Irritation: Causes skin and eye irritation; may trigger allergic dermatitis upon prolonged contact.
  • Toxicity: Inhalation or ingestion can damage the respiratory system, liver, and kidneys.
• Environmental Risks:
  • Persists in soil and water; toxic to aquatic life.
  • Biodegradation is slow, requiring proper waste disposal (e.g., incineration under controlled conditions).

Storage and Handling

• Store in a cool, dry, well-ventilated area, sealed in airtight containers to prevent oxidation.
• Avoid contact with moisture, strong acids, and oxidizing agents.
• Use personal protective equipment (PPE): gloves, goggles, and a respirator (N95 or higher) to prevent inhalation and skin exposure.
