    n-BUTENE ICSC: 0396  IMPORTANT DATA PHYSICAL STATE; APPEARANCE: ODOURLESS COLOURLESS COMPRESSED LIQUEFIED GASPHYSICAL DANGERS: The gas is heavier than air, and may travel along the ground; distant ignition possible. CHEMICAL DANGERS: The substance may polymerize. Reacts violently with oxygen and oxidants, causing fire and explosion hazard.OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. INHALATION RISK: On loss of containment this gas can cause suffocation by lowering the oxygen content of the air in confined areas.EFFECTS OF SHORT-TERM EXPOSURE: Rapid evaporation of the liquid may cause frostbite. PHYSICAL PROPERTIES Boiling point: -6 °CMelting point: -185 °CSolubility in water: noneVapour pressure, kPa at 21 °C: 464Relative vapour density (air = 1): 1.93Flash point: Flammable GasAuto-ignition temperature: 385 °CExplosive limits, vol% in air: 1.6-10.0
