化学的特性
1-Hexene, C6H12, is a colorless liquid, which is highly
volatile and flammable. Hexene is a component of refinery
gas and coffee aroma.
物理的性質
Clear, colorless, flammable liquid with a characteristic, sweetish odor similar to hexane or 1-pentene.
An odor threshold concentration of 140 ppb
v was reported by Nagata and Takeuchi (1990).
使用
1-Hexene is used as a solvent, paint thinner and a medium for conducting chemical reactions. It is a commoner and used in the preparation of both low density and high density polyethylenes. It acts as an adhesives, lubricants, lubricant additives and sealant chemicals. Further, it is used in the preparation of hex-1-en-3-one, heptanal and heptanoic acid. It is also employed in the synthesis of linear plasticizers, oxo-alcohols, motor fuels, automotive additives and biodegradable surfactants. In addition to this, it is used in the preparation of mercaptans, flavors and fragrances, alkyl metals, halides and alkyl silanes.
定義
ChEBI: An alkene that is hexane carrying a double bond at position 1.
一般的な説明
A clear colorless liquid with a petroleum like odor. Flash point -9°F. Less dense than water and insoluble in water. Vapors heavier than air. Used as a solvent, paint thinner, and chemical reaction medium.
空気と水の反応
Highly flammable. Insoluble in water.
反応プロフィール
1--HEXENE may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas.
危険性
Irritant. Highly flammable, dangerous fire
risk.
健康ハザード
Inhalation may cause giddiness or incoordination similar to that from gasoline vapor. Prolonged exposure to high concentrations may induce loss of consciousness or death.
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.
環境運命予測
Biological. Biooxidation of 1-hexene may occur yielding 5-hexen-1-ol, which may oxidize to
give 5-hexenoic acid (Dugan, 1972). Washed cell suspensions of bacteria belonging to the genera
Mycobacterium, Nocardia, Xanthobacter, and Pseudomonas and growing on selected alkenes
metabolized 1-hexene to 1,2-epoxyhexane (Van Ginkel et al., 1987).
Photolytic. The following rate constants were reported for the reaction of 1-hexene and OH
radicals in the atmosphere: 1.9 x 10
-12 cm
3/molecule?sec at 300 K (Hendry and Kenley, 1979); 3.75
x 10
-11 cm
3/molecule?sec at 295 K (Atkinson and Carter, 1984); 3.18 x 10

(Atkinson, 1990). The following rate constants were reported for the reaction of 1-hexene and
ozone in the atmosphere: 1.10 x 10
-17 cm
3/molecule?sec (Bufalini and Altshuller, 1985); 9.0 x 10

3/molecule?sec (Cadle and Schadt, 1952); 1.40 x 10

3/molecule?sec (Cox and Penkett,
1972); 1.08 x 10
-17 cm
3/molecule?sec at 294 K (Adeniji et al., 1981).
Chemical/Physical. Complete combustion in air yields carbon dioxide and water.
1-Hexene is not expected to hydroxyze in water.
純化方法
Purify it by stirring over Na/K alloy for at least 6hours, then fractionally distil it from sodium under nitrogen. [Beilstein 1 IV 828.]
