Product Description

Product Description

Basic Information

  • Product Name: N,N-Dimethylaniline
  • Chemical Formula:C8H11N or (CH3)2NC6H5
  • CAS Number:121-69-7
  • Molar Mass:121.18 g/mol
  • Structure:A secondary aromatic amine with two methyl groups (-CH3) attached to the nitrogen atom of aniline.

Physical Properties
Property Description
Appearance Colorless to light yellow oily liquid (darkens on exposure to air/light)
Odor Characteristic aromatic amine odor (fishy or ammonia-like)
Melting Point -57°C
Boiling Point 193-194°C (at 1 atm)
Density 0.956 g/cm³ (at 20°C)
Solubility Insoluble in water; miscible with ethanol, diethyl ether, benzene, and most organic solvents
Vapor Pressure 0.3 mmHg (at 25°C)

Chemical Properties
  1. Basicity:
    • Acts as a weak base due to the lone pair on the nitrogen atom. Reacts with strong acids to form water-soluble salts (e.g., hydrochloride salt):(CH3)2NC6H5+HCl→[(CH3)2NC6H5H]+Cl
  2. Electrophilic Substitution:
    • The amino group (-N(CH3)2) is an ortho/para-directing group in aromatic substitution reactions (e.g., nitration, sulfonation).
      • Example: Nitration primarily yields para-nitro-N,N-dimethylaniline.
  3. Oxidation:
    • Easily oxidized in air, forming colored quinone imine derivatives (responsible for darkening).
  4. Acylation:
    • Reacts with acyl chlorides or anhydrides to form amides (e.g., N,N-dimethylacetanilide).
  5. Condensation Reactions:
    • Forms Schiff bases with aldehydes/ketones and participates in azo coupling reactions (critical in dye synthesis).

Main Applications
  1. Dye Industry:
    • Key intermediate in synthesizing azo dyes (e.g., methyl orange, crystal violet) and triarylmethane dyes (e.g., malachite green).
  2. Rubber Industry:
    • Used as a curing accelerator and antioxidant in rubber processing.
  3. Pharmaceuticals:
    • Intermediate in synthesizing local anesthetics (e.g., procaine derivatives) and antimalarial drugs.
  4. Organic Synthesis:
    • Solvent and catalyst in chemical reactions (e.g., as a base in condensation reactions).
  5. Agriculture:
    • Intermediate in pesticide and herbicide production.

Safety and Hazards
Hazard Summary
  • Health Risks:
    • Toxicity: Harmful via inhalation, ingestion, or skin absorption. Causes methemoglobinemia (reduces blood's oxygen-carrying capacity), leading to cyanosis, headache, and dizziness.
    • Carcinogenicity: Classified as a possible human carcinogen (IARC Group 3: unclassifiable based on current evidence).
    • Irritation: Vapors irritate the eyes, nose, and throat; prolonged skin contact may cause dermatitis.
  • Environmental Risks:
    • Toxic to aquatic life; may bioaccumulate in ecosystems.
  • Fire and Explosion:
    • Combustible liquid; vapor forms explosive mixtures with air (flash point: 62°C). Burns produce toxic fumes (e.g., nitrogen oxides).

Safety Precautions
  • Personal Protection:
    • Wear chemical-resistant gloves, goggles, and a respirator (e.g., N95 for dust/vapors) in enclosed spaces.
  • Storage and Handling:
    • Store in tightly sealed containers in a cool, well-ventilated area, away from oxidizers, acids, and light.
    • Avoid prolonged skin contact; use explosion-proof equipment in areas with potential ignition sources.
  • Emergency Response:
    • For spills, contain with absorbent materials and transfer to sealed containers for disposal. Flush skin/eyes with water for 15 minutes; if ingested, do not induce vomiting and seek medical help immediately.
