1-HEPTENE Usage And Synthesis
Chemical PropertiesHeptene is a colorless liquid. Mild, gasoline like odor.
Chemical Propertiesclear colorless liquid
Chemical Properties1-Heptene is a colorless, highly flammable liquid with specific gravity 0.697.
Uses1-Heptene can be used as a reactant for the gold(I)-catalyzed stereoselective olefin cyclopropanation of alkenes. Also it is a volatile organic compound which acts as a pollutant in the atmosphere.
UsesOrganic synthesis.
DefinitionChEBI: 1-Heptene is a hydrocarbon.
Production MethodsHeptene is produced in a process involving the oligomerization of ethene in the presence of aluminum alkyls.

General DescriptionThe liquid phase alkylation of toluene with 1-heptene has been investigated over a HFAU zeolite.
HazardFlammable, dangerous fire risk.
Health HazardRecommended Personal Protective Equipment: Safety goggles or face shield; Symptoms Following Exposure: High concentrations may produce slight irritation of eyes and respiratory tract; also acts as simple asphyxiant and slight anesthetic; General Treatment for Exposure: Remove from exposure. Administer artificial respirator if needed; Toxicity by Inhalation: Data not available; Short-Term Inhalation Limits: Data not available; Toxicity by Ingestion: Data not available; Late Toxicity: Data not available; Vapor (Gas) Irritant Characteristics: Vapors cause a slight smarting of the eyes or respiratory system if present in high concentrations. Effects are temporary; Liquid or Solid Irritant Characteristics: Minimum hazard. If spilled on clothing and allowed to remain, may cause smarting and reddening of the skin; Odor Threshold: Data not available.
Chemical ReactivityReactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
Potential ExposureA potential danger to those involved in use as a plant growth retardant or in organic synthesis.
ShippingUN2278 n-Heptene, Hazard Class: 3; Labels: 3-Flammable liquid.
Purification MethodsDistil hept-1-ene from sodium, then carefully distil it fractionally using an 18-in gauze-packed column. It can also be purified by azeotropic distillation with EtOH. It usually contains the 2-and 3-isomers as impurities. These can be removed by gas chromatography using a Carbowax column at 70o. [Beilstein 1 IV 857.]
IncompatibilitiesVapor may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epox ides. May react exothermically with reducing agents releasing flammable hydrogen gas.
Waste DisposalDissolve or mix the material with a combustible solvent and burn in a chemical incinera tor equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
