trans-2-Pentene Chemical Properties,Uses,Production
Chemical Properties
clear colourless to slightly yellowish liquid with a disagreeable odor.
General Description
trans-2-Pentene is a colorless liquid with a hydrocarbon smell. It is primarily found in technical grade as a mixture of isomers. It is commonly used as a solvent, in organic synthesis, and as a polymerization inhibitor.
Air & Water Reactions
Highly flammable. Insoluble in water.
Reactivity Profile
The unsaturated aliphatic hydrocarbons, such as 2-PENTENE, 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.
Safety Profile
A dangerous fire and explosion hazard when exposed to heat or flame; can react vigorously with oxidizing materials. When heated to decomposition it emits acrid smoke and irritating fumes.
Environmental Fate
Chemical/Physical. Complete combustion in air yields carbon dioxide and water.
Purification Methods
It is treated as above and washed with water, dried over anhydrous Na2CO3, and fractionally distilled. The middle cut is purified by two passes of fractional melting. [Beilstein 1 IV 814.]
