| Hazard Information | Back Directory | [Hazard]
Flammable, dangerous fire risk. | [Potential Exposure]
A potential danger to those involved
in use as a plant growth retardant or in organic synthesis. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, includ ing resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medi cal attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit. | [Shipping]
UN2278 n-Heptene, Hazard Class: 3; Labels:
3-Flammable liquid. | [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. | [Description]

The liquid phase alkylation of toluene with 1-heptene has been investigated over a HFAU zeolite. | [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. | [storage]
Color Code- Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.Prior to working with heptene you should be trained on itsproper handling and storage. Before entering confined spacewhere heptene may be present, check to make sure that anexplosive concentration does not exist. Store in tightlyclosed containers in a cool, well-venti lated area away fromoxidizers. Metal containers involving the transfer of thischemical should be grounded and bonded. Where possible,automatically pump liquid from drums or other storage con-tainers to process containers. Drums must be equipped withself-closing valves， pressure vacuum bungs， and flamearresters. Use only nonsparking tools and equipment, espe-cially when opening and closing containers of this chemi-cal. Sources of ignition, such as smoking and open flames,are prohibited where this chemical is used, handled, orstored in a manner that could create a potential fire orexplosion hazard. Wherever this chemical is used, handled,manufactured, or stored, use explosion-proof e lectricalequipment and fittings. | [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.] |
