2-BUTENE Chemical Properties,Uses,Production

Chemical Properties

colourless gas

General Description

A colorless liquefied petroleum gas. An asphyxiant. Flammability limits of 1.8-9% by volume.

Air & Water Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

The unsaturated aliphatic hydrocarbons, such as 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 730, 1 IV 781.] HIGHLY FLAMMABLE.
