PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance WHITE OR COLOURLESS FLUFFY CRYSTALS.
Chemical dangers Decomposes on heating and under the influence of UV light. This produces toxic and corrosive fumes including hydrogen chloride (see ICSC 0163) and nitrogen dioxide (see ICSC 0930).
Molecular mass: 256.5
Decomposes at 208°C Melting point: 148-150°C Density: 1.85 g/cm³ Solubility in water, g/100ml at 25°C: 0.04 (none) Vapour pressure at 25°C: negligible Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00
EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.
Effects of short-term exposure May cause mechanical irritation.
Inhalation risk A nuisance-causing concentration of airborne particles can be reached quickly when dispersed.
Effects of long-term or repeated exposure
OCCUPATIONAL EXPOSURE LIMITS
