2,4-Diaminotoluene Chemical Properties,Uses,Production

Chemical Properties

brown crystalline powder, crystals or flakes

Chemical Properties

Toluene-2,4-diamine takes the form of colorless needles.

Uses

2,4-Toluenediamine is used as an intermedi ate in the manufacture of dyes.

Uses

Aromatic amines likely to have high carcinogenic potency. QSARs of aromatic amines.

Definition

ChEBI: An aminotoluene that is para-toluidine with an additional amino group at position 2.

General Description

A colorless crystalline solid. Toxic by ingestion and inhalation. Irritates skin and eyes. Slightly soluble in water and neutrally buoyant in water. Decomposes with emission of toxic oxides of nitrogen at high temperatures. Used in making dyes.

Air & Water Reactions

Soluble in water, alcohol and ether.

Reactivity Profile

2,4-Diaminotoluene neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides. Reacts vigorously with oxidizing agents [USCG, 1999].

Hazard

A possible carcinogen.

Health Hazard

2,4-Toluenediamine is a cancer-causing compound. Animal studies indicate sufficient evidence of its carcinogenicity. Oral applicationof this amine resulted in blood and liver cancers in rats and mice.
The acute oral toxicity was moderate tohigh in test animals. It produced methe moglobinemia, cyanosis, and anemia. Theoral LD50 value in rats is 250–300 mg/kg.It is a mild skin irritant. The irritation effecton rabbits’ eyes was moderate
Thysen and associates (1985a,b) evaluated the reproductive toxicity of 2,4-toluenediamine in adult male rats. Dietscontaining up to 0.03% of amine fed to theanimals for 10 weeks reduced the fertilityand exerted an inhibitory or toxic effect onspermatogenesis. The amine affected andro gen action in the male rats and induced dam age to the germinal components of the testes.
2,4-Toluenediamine tested positive to thehistidine reversion-Ames and Drosophilamelanogaster sex-linked lethal tests. Whenadministered to rats pretreated with themicrosomal enzyme inducers phenobarbital , β-naphthoflavone ,or 3-methylcholanthrene , the uri nary metabolites showed increased muta genic activity compared with the controls(Reddy et al. 1986).

Fire Hazard

Noncombustible solid. It ignites when mixed with red fuming nitric acid. Reactions with strong oxidizers and hypochlorites can be violent.

Safety Profile

Confirmed carcinogen with experimental carcinogenic data. Poison by intraperitoneal and subcutaneous routes. Experimental reproductive effects. Human mutation data reported. A skin and eye irritant. This material has a marked toxic action upon the liver and can cause fatty degeneration of that organ. When heated to decomposition it emits toxic fumes of NOx. See also other toluenediamine entries and AROMATIC AMINES.

Potential Exposure

Toluene-2,4-diamine is a chemical intermediate for toluene diisocyanate (used in the production of flexible and rigid polyurethane foams, polyurethane coatings; cast elastomers including fabric coatings and polyurethane and other adhesives), for dyes used on textiles; leather, furs; and in hair-dye formulations.

First aid

Skin Contact: Flood all areas of body that have contacted the substance with water. Don’t wait to remove contaminated clothing; do it under the water stream. Use soap to help assure removal. Isolate contaminated clothing when removed to prevent contact by others. Eye Contact: Remove any contact lenses at once. Flush eyes well with copious quantities of water or normal saline for at least 20-30 minutes. Seek medical attention. Inhalation: Leave contaminated area immediately; breathe fresh air. Proper respiratory protection must be supplied to any rescuers. If coughing, difficult breathing or any other symptoms develop, seek medical attention at once, even if symptoms develop many hours after exposure. Ingestion: If convulsions are not present, give a glass or two of water or milk to dilute the substance. Assure that the person’s airway is unobstructed and contact a hospital or poison center immediately for advice on whether or not to induce vomiting.

Shipping

UN1709 2,4-Toluylenediamine, solid or 2,4Toluenediamine, solid, Hazard Class: 6.1; Labels: 6.1-Poisonous materials. UN3814 2,4-Toluylenediamine, solution or 2,4-Toluenediamine, solution, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

Purification Methods

Recrystallise the diamine from water containing a very small amount of sodium dithionite (to prevent air oxidation), and dry it under vacuum. It also crystallises from *benzene. [Beilstein 13 IV 235.]

Incompatibilities

Strong acids; chloro formates, oxidizers.

Waste Disposal

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal. Controlled incineration (oxides of nitrogen are removed from the effluent gas by scrubbers and/or thermal devices).
