CIS-2-BUTENE Chemical Properties,Usage,Production
Chemical Properties
colourless gas
Definition
ChEBI: Cis-but-2-ene is a but-2-ene.
General Description
A colorless liquefied petroleum gas. Boiling point 3.7°C. Asphyxiate gas. Flammability limits in air 1.8-9.7% by volume.
Air & Water Reactions
Highly flammable. Insoluble in water.
Reactivity Profile
The unsaturated aliphatic hydrocarbons, such as CIS-2-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. Aluminum borohydride reacts with alkenes and in the presence of oxygen, combustion is initiated even in the absence of moisture.
Purification Methods
The gas is dried with CaH2 and purified by gas chromatography. [Beilstein 1 H 205, 1 II 176, 1 III 728, 1 IV 778.] HIGHLY FLAMMABLE.
