Most important symptoms/effects, acute and delayed
ACUTE/CHRONIC HAZARDS: This compound is toxic. It is a local irritant. (NTP, 1992)
Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Organic bases/Amines and related compounds/

SECTION 10: Stability and reactivity
Reactivity
NIOSH considers toluenediamine to be a potential occupational carcinogen. Toluenediamine
On combustion, forms toxic fumes of nitrogen oxides.
Chemical stability
no data available
Possibility of hazardous reactions
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.

- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
Persistence and degradability
AEROBIC: 2,6-Diaminotoluene, (ring-labeled), produced 34% 14-CO2 evolution in 375 days using a soil inoculum in the shake flask test(1). Adsorption to soil is expected to attenuate biodegradation(2). When incubated with a synthetic batch activated sludge acclimated to the 2,4- and 2-6-isomers, diaminoluenes, present at 300 mg/L, were 80% biodegraded in 4 days(3).
Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for 2,6-diaminotoluene(SRC), using an estimated log Kow of 0.16(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
Using aerobic conditions with a Washington silt loam surface soil (21% sand; 60% silt; 19% clay; pH 5; 1.3% total organic carbon) from a farm field planted with a rotation of corn and soybeans near Bethehem, PA and a Freehold sandy loam soil (53% sand; 40% silt; 7% clay; pH 5.8; 1.6% total organic carbon) from the Rutgers Experimental Farm, Adelphia, NJ, the Koc of 2,6-diaminotoluene were measured to be 706 and 708, respectively. Under anaerobic conditions, Koc values were 588 and 546, respectively(1). According to a classification scheme(2), this estimated Koc value suggests that 2,6-diaminotoluene is expected to have low mobility in soil. The estimated pKa of 2,6-diaminotoluene is 4.69(3), indicating that this compound will exist partially in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Aromatic amines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(5,6), suggesting that mobility may be much lower in some soils.
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
