Chemical Safety
0403 BUTYRALDEHYDE
IMPORTANT DATA
Physical State; Appearance Routes of exposure
COLOURLESS LIQUID, WITH PUNGENT ODOUR. The substance can be absorbed into the body by inhalation of its vapour
and by ingestion.
Physical dangers
The vapour is heavier than air and may travel along the ground; distant Inhalation risk
ignition possible. No indication can be given about the rate in which a harmful concentration
in the air is reached on evaporation of this substance at 20/C.
Chemical dangers
The substance can presumably form explosive peroxides. The substance Effects of short-term exposure
may polymerize. Reacts with amines, oxidants, strong bases and acids. The substance is irritating to the eyes, the skin and the respiratory tract.
Occupational exposure limits
TLV not established.
MAK not established.

Boiling point: 74.8/C Relative vapour density (air = 1): 2.5
Melting point: -99/C Flash point: -12/C c.c.
Density: 0.8 g/cm3 Auto-ignition temperature: 230/C
Solubility in water, g/100 ml: 7 Explosive limits, vol% in air: 1.9-12.5
Vapour pressure, kPa at 20/C: 12.2 Octanol/water partition coefficient as log Pow: 0.88
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
Check for peroxides prior to distillation; eliminate if found.
Card has been partially updated in August 2007: see Storage.
