CIS-2-PENTENE Chemical Properties,Uses,Production

Chemical Properties

colourless liquid

General Description

A colorless liquid with a hydrocarbon odor. Usually found as a technical grade consisting of a mixture of isomers. Insoluble in water. 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.

Purification Methods

Dry it with sodium wire and fractionally distil it, or purify it by azeotropic distillation with MeOH, followed by washing out the MeOH with water, drying and distilling. Also purify it by chromatography through silica gel and alumina [Klassen & Ross J Phys Chem 91 3668 1987]. [Beilstein 1 IV 814.]
