Product Description

Product Description

 

• Product Name: N,N-Dimethylbenzylamine
• Chemical Formula: C8H11N
• Other Names: Dimethylbenzylamine, BDMA, N-Benzyl-N,N-dimethylamine.
• Appearance: Colorless to light yellow transparent liquid, with a strong amine odor (similar to fishy or ammonia-like smell).
• Solubility: Miscible with organic solvents (e.g., ethanol, ether, benzene); slightly soluble in water (≈2 g/100 mL at 20°C).

Physical Properties

• Density: 0.91 g/cm³ (20°C)
• Melting Point: −75°C
• Boiling Point: 180-184°C
• Refractive Index: 1.512-1.514 (20°C)
• Flash Point: 60°C (closed cup)
• Vapor Pressure: 0.13 kPa (20°C)

Chemical Properties

1. Basicity:
   • As a tertiary amine, it readily accepts protons, forming stable ammonium salts in acidic conditions.
2. Nucleophilicity:
   • The nitrogen atom can act as a nucleophile in reactions such as acylation, alkylation, or condensation.
3. Oxidation and Reduction:
   • Oxidized under strong conditions to form N-oxide or amide; reducible to corresponding hydrocarbons under specific catalytic hydrogenation.
4. Reactions with Electrophiles:
   • The benzyl group may undergo electrophilic substitution on the benzene ring (e.g., halogenation, nitration), with the dimethylamino group indirectly influencing substitution via electron donation.

Applications

1. Catalyst in Polymer Synthesis:
   • Urethane Foams: Promotes the reaction between isocyanates and polyols in polyurethane production, controlling curing speed and foam structure.
   • Epoxy Resins: Catalyzes curing reactions (e.g., with acid anhydrides or amines).
2. Organic Synthesis Intermediate:
   • Pharmaceuticals: Used in synthesizing antihistamines, antidepressants, and local anesthetics (e.g., intermediates for benzodiazepines).
   • Agrichemicals: Precursor for insecticides and fungicides.
3. Solvent and Corrosion Inhibitor:
   • As a polar solvent for resins, dyes, and coatings; acts as a corrosion inhibitor in metalworking fluids.
4. Catalyst in Chemical Reactions:
   • Promotes condensation, esterification, and Michael addition reactions due to its basicity and nucleophilicity.

Safety and Storage

• Hazards:
  • Toxicity: Toxic by inhalation, skin contact, or ingestion. Causes severe eye and skin irritation; may damage the respiratory system. LD50 (rat, oral) ≈200-400 mg/kg.
  • Flammability: Combustible; vapor-air mixtures are explosive.
  • Corrosivity: Corrosive to metals and tissues.
• Storage Conditions:
  • Store in a tightly sealed, cool, ventilated area, away from heat, flames, oxidants, and acids.
  • Use explosion-proof containers and avoid prolonged air exposure (amines may oxidize).
• Handling Precautions:
  • Wear chemical-resistant gloves, goggles, and a respirator; work in a fume hood.
  • In case of leakage, isolate the area, absorb with inert materials (e.g., sand), and dispose of according to hazardous waste regulations.
