    • Highly flammable. Insoluble in water.

  • Reactivity Profile

    The unsaturated aliphatic hydrocarbons, such as 1-BUTENE, 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. May react with oxidizing materials. Aluminum borohydride reacts with alkenes and in the presence of oxygen, combustion is initiated even in the absence of moisture.

  • Fire Hazard

    1-BUTENE is flammable. Vapor is heavier than air and may travel long distances to an ignition source and flash back.
