0582 2,4-TOLUENEDIAMINE
IMPORTANT DATA
Physical State; Appearance Routes of exposure
COLOURLESS CRYSTALS. TURNS DARK ON EXPOSURE TO The substance can be absorbed into the body by inhalation of its
AIR. aerosol or vapour (when in molten state), through the skin and by
ingestion.
Chemical dangers
Inhalation risk
The substance decomposes on burning producing toxic fumes of
nitrogen oxides. No indication can be given about the rate in which a harmful
concentration in the air is reached on evaporation of this
Occupational exposure limits substance at 20/C.
TLV not established.
Effects of short-term exposure
MAK: skin absorption (H); sensitization of skin (Sh); Carcinogen
category: 2; (DFG 2005). The substance irritates the eyes, the skin and the respiratory
tract. The hot liquid may cause severe skin burns. The substance
may cause effects on the liver and blood, resulting in liver damage
and formation of methaemoglobin. The effects may be delayed.
Medical observation is indicated.
Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization.
This substance is possibly carcinogenic to humans. May cause
genetic damage in humans.
PHYSICAL PROPERTIES
Boiling point: 292/C Relative vapour density (air = 1): 4.2
Melting point: 99/C Relative density of the vapour/air-mixture at 20/C (air = 1): 1.00
Relative density (water = 1): see Notes Flash point: 149/C
Solubility in water: good Octanol/water partition coefficient as log Pow: 0.35
Vapour pressure, kPa at 106.5/C: 0.13
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
May be handled and shipped in the molten state. Density of the solid is unknown in literature, but density of the liquid (water = 1) at
100/C is 1.045.
Depending on the degree of exposure, periodic medical examination is suggested.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Azogen Developer H, Benzofur MT, Eucanine GB, Fouramine, Fourrine, Pelagol, Pontamine Developer TN, Tertral G, Zoba GKE, and
Zogen Developer H are trade names.
Card has been partly updated in October 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
