1446 N-PHENYL-1,4-BENZENEDIAMINE
IMPORTANT DATA
Physical State; Appearance Routes of exposure
PURPLE CRYSTALLINE POWDER OR NEEDLES. The substance can be absorbed into the body by inhalation and
by ingestion.
Chemical dangers
Inhalation risk
On combustion, forms toxic fumes (carbon monoxide, nitrogen
oxides). Reacts with strong acids and strong oxidants. Evaporation at 20掳C is negligible; a harmful concentration of
airborne particles can, however, be reached quickly when
dispersed, especially if powdered.
Occupational exposure limits
TLV not established.
Effects of short-term exposure
The substance is irritating to the skin and the eyes. The
substance may cause effects on the blood following ingestion,
resulting in the formation of methaemoglobin. Medical
observation is indicated. The effects may be delayed.
Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization.
PHYSICAL PROPERTIES
Boiling point: 354掳C Vapour pressure, Pa at 20掳C: 0.000076
Melting point: 75掳C Flash point: 193掳C
Density: 1.09 g/cm3 Octanol/water partition coefficient as log Pow: 2.4 (calculated)
Solubility in water, g/100 ml at 20掳C: 0.05
ENVIRONMENTAL DATA
This substance may be hazardous in the environment; special attention should be given to aquatic organisms.
NOTES
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
