1-ヘプテン 化学特性,用途語,生産方法
外観
無色～うすい黄色、液体
化学的特性
1-Heptene is a colorless, highly flammable liquid
with specific gravity 0.697.
使用
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.
調製方法
Heptene is produced in a process involving the oligomerization
of ethene in the presence of aluminum alkyls.
一般的な説明
The liquid phase alkylation of toluene with 1-heptene has been investigated over a HFAU zeolite.
危険性
Flammable, dangerous fire risk.
健康ハザード
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.
化学反応性
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.
職業ばく露
A potential danger to those involved
in use as a plant growth retardant or in organic synthesis.
輸送方法
UN2278 n-Heptene, Hazard Class: 3; Labels:
3-Flammable liquid.
純化方法
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.]
不和合性
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.
廃棄物の処理
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.
