The Uses of 2,6-Diaminotoluene

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

Definition

ChEBI: A diamine that is toluene in which both of the hydrogens ortho- to the methyl group are replaced by amino groups.

Production Methods

2,6-Toluenediamine is usually produced as a by-product with 2,4-TDA in mixtures containing 20% 2,6-isomer and 80% 2,4-isomer. It is used primarily in the manufacture of toluene diisocyanate, the predominant isocyanate in the flexible polyurethane foams and elastomers industry.
Human exposure to 2,6-TDA may occur indirectly via exposure to toluene diisocyanate mixture containing 2,6- toluenediisocyanate, which is known to hydrolyze to 2,6- TDA rapidly upon contact with water. Workers in some plastics and elastomers industries may be exposed to atmosphere containing TDI.

General Description

Colorless prisms (from water).

Air & Water Reactions

Water soluble.

Reactivity Profile

2,6-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. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Health Hazard

ACUTE/CHRONIC HAZARDS: 2,6-Diaminotoluene is toxic. It is a local irritant.

Fire Hazard

Flash point data for 2,6-Diaminotoluene are not available. 2,6-Diaminotoluene is probably combustible.
