1173 FUMARIC ACID
IMPORTANT DATA
Physical State; Appearance Routes of Exposure
ODOURLESS, COLOURLESS CRYSTALLINE POWDER. The substance can be absorbed into the body by ingestion.
Physical Dangers Inhalation Risk
Dust explosion possible if in powder or granular form, mixed Evaporation at 20C is negligible; a nuisance-causing
with air. concentration of airborne particles can, however, be reached
quickly.
Chemical Dangers
Effects of Short-term Exposure
On combustion, forms irritating fumes of maleic anhydride.
The substance irritates the eyes, the skin and the respiratory
tract.
Occupational Exposure Limits
TLV not established.
PHYSICAL PROPERTIES
Sublimation point: 200C Solubility in water: 0.63 g/100 ml at 25C
Relative density (water = 1): 1.63 Auto-ignition temperature: (powder) 740C
ENVIRONMENTAL DATA
NOTES
Melting point 287C (closed capillary, rapid heating); partial carbonization and formation of maleic anhydride occur at 230C
(open vessel). Health effects of exposure to the substance have been investigated, but none has been found.
