CIS-2-PENTENE Chemical Properties,Uses,Production

Chemical Properties

colourless liquid

Physical properties

Clear, colorless, flammable liquid with a disagreeable odor.

Uses

Polymerization inhibitor; organic synthesis.

Uses

cis-2-Pentene was used to study the adsorption of cis-2-pentene on clean and D2 preadsorbed Pd(111) surface.

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.

Source

Schauer et al. (2001) measured organic compound emission rates for volatile organic compounds, gas-phase semi-volatile organic compounds, and particle-phase organic compounds from the residential (fireplace) combustion of pine, oak, and eucalyptus. The gas-phase emission rate of cis-2-pentene was 10.4 mg/kg of pine burned. Emission rates of cis-2-pentene were not measured during the combustion of oak and eucalyptus.
California Phase II reformulated gasoline contained cis-2-pentene at a concentration of 2.29 g/kg. Gas-phase tailpipe emission rates from gasoline-powered automobiles with and without catalytic converters were 0.44 and 42.3 mg/km, respectively (Schauer et al., 2002).

Environmental Fate

Photolytic. The rate constant for the reaction of cis-2-pentene and OH radicals in the atmosphere at 300 K is 3.9 x 10-13 cm3/molecule?sec (Hendry and Kenley, 1979). Atkinson (1990) reported a rate constant of 6.50 x 10-11 cm3/molecule?sec for the same reaction.
Chemical/Physical. Complete combustion in air yields carbon dioxide and water.

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.]
