MALONONITRILE

ICSC: 1466

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS CRYSTALS OR WHITE POWDER. Physical dangers Chemical dangers The substance polymerizes under the influence of temperatures above 130°C or under the influence of bases. This generates fire or explosion hazard. Decomposes on heating. This produces toxic and corrosive gases including hydrogen cyanide and nitrogen oxides. Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001).	Formula: C₃H₂N₂ / NCCH₂CN Molecular mass: 66.1 Boiling point: 218-220°C Melting point: 30-34°C Density: 1.19 g/cm³ Solubility in water, g/100ml at 20°C: 13.3 (moderate) Vapour pressure, Pa at 25°C: 27 Relative vapour density (air = 1): 2.3 Flash point: 112°C o.c. Octanol/water partition coefficient as log Pow: -0.6

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation, through the skin and by ingestion. Effects of short-term exposure The substance is severely irritating to the eyes, skin and respiratory tract. The substance may cause effects on the cellular respiration (inhibition). This may result in convulsions, cardiac disorders and respiratory failure. Exposure at high levels could cause death. Medical observation is indicated. The effects may be delayed.	Inhalation risk A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C. Effects of long-term or repeated exposure
