| Chemical Properties | Heptene is a colorless liquid. Mild, gasoline like odor. |
| Chemical Properties | clear colorless liquid |
| Chemical Properties | 1-Heptene is a colorless, highly flammable liquid with specific gravity 0.697. |
| Uses | 1-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. |
| Uses | Organic synthesis. |
| Definition | ChEBI: 1-Heptene is a hydrocarbon. |
| Production Methods | Heptene is produced in a process involving the oligomerization of ethene in the presence of aluminum alkyls. |

| General Description | The liquid phase alkylation of toluene with 1-heptene has been investigated over a HFAU zeolite. |
| Hazard | Flammable, dangerous fire risk. |
| Health Hazard | Recommended 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 Reactivity | Reactivity 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 Exposure | A potential danger to those involved in use as a plant growth retardant or in organic synthesis. |
| Shipping | UN2278 n-Heptene, Hazard Class: 3; Labels: 3-Flammable liquid. |
| Purification Methods | Distil 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.] |
| Incompatibilities | Vapor 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 Disposal | Dissolve 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. |
