IMPORTANT DATA
Physical State; Appearance Routes of exposure
COLOURLESS TO WHITE HYGROSCOPIC CRYSTALS The substance can be absorbed into the body by inhalation of
its aerosol and by ingestion.
Physical dangers
Inhalation risk
Dust explosion possible if in powder or granular form, mixed
with air. Evaporation at 20掳C is negligible; a harmful concentration of
airborne particles can, however, be reached quickly when
dispersed, especially if powdered.
Chemical dangers
Reacts violently with oxidants.
Effects of short-term exposure
The substance is irritating to the eyes and the respiratory tract.
Occupational exposure limits
TLV not established.
PHYSICAL PROPERTIES
Boiling point: 210掳C Relative density of the vapour/air-mixture at 20掳C (air = 1): 1.0
Melting point: 127掳C Flash point: 107掳C
Density: 1.1 g/cm3 Auto-ignition temperature: 388掳C
Solubility in water, g/100 ml at 20掳C: 83 Explosive limits, vol% in air: 1.1-11.4
