1-PENTENE Chemical Properties,Uses,Production
Chemical Properties
Pentene is a colorless liquid.
Safety Profile
Moderately toxic. Very flammable; reacts with heat, flame, and oxidizing materials. To fight fire, use foam, CO2, dry chemical.
Potential Exposure
Workers in petroleum refineries and petrochemical plants.
Shipping
UN1108 1-Pentene, Hazard Class: 3; Labels: 3-Flammable liquid
Incompatibilities
Vapors may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Excessive heat may cause polymerization. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, heat. Incompatible with strong reducing agents such as hydrides; oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.
Waste Disposal
Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
