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.
