29012990 | [Safety Profile]
A simple asphyxiant.
Very dangerous fire hazard when exposed to
heat, flame, or oxidizers. To fight fire, use
dry chemical, CO2, foam. When heated to
decomposition it emits acrid smoke and
irritating fumes. | [Hazardous Substances Data]
563-46-2(Hazardous Substances Data) |
| Hazard Information | Back Directory | [General Description]
A colorless volatile liquid with a disagreeable odor. Insoluble in water and less dense than water. Flash point below 0°F. Vapors are heavier than air. Used to make other chemicals. | [Reactivity Profile]
The unsaturated aliphatic hydrocarbons, such as 2-METHYL-1-BUTENE(563-46-2), are generally much more reactive than the alkanes. Strong oxidizers may react vigorously with them. Reducing agents can react exothermically to release gaseous hydrogen. In the presence of various catalysts (such as acids) or initiators, compounds in this class can undergo very exothermic addition polymerization reactions. | [Air & Water Reactions]
Highly flammable. Insoluble in water. | [Hazard]
Highly flammable, dangerous fire and
explosion risk. | [Health Hazard]
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution. | [Chemical Properties]
colourless liquid | [Definition]
ChEBI: An alkene that is but-1-ene carrying a methyl substituent at position 2. |
