Product Description

Basic Information

Product Name: N,N-Dimethyl-o-toluidine
Alias: 2-Methyl-N,N-dimethylaniline; o-Toluidine, N,N-dimethyl-
CAS Number: 613-69-4
Molecular Formula: C9H13N
Molecular Weight: 135.21 g/mol

Physical Properties

Appearance and State:
- Colorless to light yellow oily liquid at room temperature, may darken upon exposure to air or light.
Melting/Boiling Point:
- Melting point: -17 °C
- Boiling point: 211-213 °C (at atmospheric pressure), distills under reduced pressure.
Solubility:
- Insoluble in water; highly soluble in organic solvents such as ethanol, diethyl ether, benzene, and chloroform.
Density: 0.96 g/cm³ (25 °C)
Refractive Index: 1.553 (20 °C)
Vapor Pressure: 0.13 mmHg (25 °C)

Chemical Properties

Amine Reactivity:
- As a tertiary aromatic amine, it exhibits weak basicity (pKb ≈ 9.5), reacting with strong acids to form water-soluble salts (e.g., hydrochloride).
Electrophilic Substitution:
- The dimethylamino group (-N(CH3)2) is an electron-donating group, activating the benzene ring for ortho- and para-substitution reactions (e.g., nitration, halogenation).
Oxidation:
- Easily oxidized by strong oxidants (e.g., potassium dichromate) to form quinone imine derivatives, which may cause color changes.
Condensation Reactions:
- Reacts with aldehydes or ketones to form Schiff bases, or with acid chlorides to produce amides.

Applications
Chemical Industry

Polymerization Catalyst:
- Used as an accelerator in curing systems for unsaturated polyester resins (e.g., in combination with organic peroxides like MEKP for room-temperature curing of fiberglass composites).
Organic Synthesis Intermediate:
- Synthesizes dyes (e.g., azo dyes, basic dyes), pharmaceuticals (e.g., antihistamines), and agricultural chemicals (e.g., herbicides).
Solvent and Additive:
- Acts as a solvent for resins, coatings, or inks; functions as a corrosion inhibitor in petroleum processing.

Laboratory and Research

Reagent:
- Used in organic synthesis reactions (e.g., as a base or nucleophile) and in analytical chemistry for colorimetric assays.

Safety and Storage
Health Hazards

Toxicity:
- Carcinogenicity: Possibly carcinogenic (IARC Group 3: Unclassifiable as to carcinogenicity in humans, but animal studies show limited evidence).
- Exposure Routes:
  - Skin Contact: Highly toxic; absorbed through skin, causing methemoglobinemia (reduced oxygen-carrying capacity of blood), leading to cyanosis, headache, and dizziness.
  - Inhalation: Vapors irritate the respiratory tract; may cause similar systemic effects as skin exposure.
  - Ingestion: Causes nausea, vomiting, and damage to the liver and kidneys.
Irritation:
- Irritates eyes and skin; prolonged contact may cause dermatitis.

Environmental Impact and Storage

Environmental Impact:
- Toxic to aquatic life; may bioaccumulate and persist in the environment. Avoid release into water, soil, or air.
Storage Conditions:
- Store in a cool, dark, ventilated place, sealed in airtight containers to prevent oxidation and vapor leakage.
- Keep away from ignition sources (flash point: 85 °C, flammable liquid) and incompatible substances (oxidants, acids, halogens).
- Use explosion-proof storage equipment; containers should be made of stainless steel or glass.

Emergency Handling

Leakage:
- Evacuate the area; wear protective gear (respirator, chemical-resistant suit) to contain spills with sand or absorbents. Transfer to sealed containers for disposal.
Firefighting:
- Use dry powder, carbon dioxide, or foam extinguishers; water may be ineffective but can cool containers.

First Aid:

Skin/Eyes: Rinse with plenty of water for 15 minutes; remove contaminated clothing.
Inhalation: Move to fresh air; provide oxygen if breathing is difficult.

Ingestion: Do not induce vomiting; drink water and seek medical help immediately.
