化学的特性
2-Methylpentane (isohexane), C6H14, is a flammable liquid
with a specific gravity of 0.653. It occurs naturally in petroleum
and gas and as a plant volatile. It is found in sources
associated with petroleum products such as petroleum manufacture,
natural gas, turbines, and automobiles.
物理的性質
Clear, colorless, very flammable liquid with an odor similar to hexane. An odor threshold
concentration of 8.9 ppm
v was reported by Nagata and Takeuchi (1990).
使用
2-Methylpentane is employed as a raw material, rubber solvent and vegetable oil extraction solvent. It is also used as a solvent in adhesives. Further, it is used as an intermediate in organic synthesis and finds application in food, preservatives, cosmetics, pharmaceuticals, beverages and flavor enhancer.
調製方法
Isohexane is manufactured by fractional distillation of
gasoline derived from crude oil or liquid product derived
from natural gas.
一般的な説明
Watery liquid with a gasoline-like odor, Floats on water. Produces an irritating vapor.
空気と水の反応
Highly flammable.
反応プロフィール
Saturated aliphatic hydrocarbons, such as ISOHEXENE, may be incompatible with strong oxidizing agents like nitric acid. Charring of the hydrocarbon may occur followed by ignition of unreacted hydrocarbon and other nearby combustibles. In other settings, aliphatic saturated hydrocarbons are mostly unreactive. They are not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents.
危険性
Flammable, dangerous fire risk, reacts vig-orously with oxidizing materials.
健康ハザード
Inhalation causes irritation of respiratory tract, cough, mild depression, cardiac arrhythmias. Aspiration causes severe lung irritation, coughing, pulmonary edema; excitement followed by depression. Ingestion causes nausea, vomiting, swelling of abdomen, headache, depression.
環境運命予測
Photolytic. When synthetic air containing gaseous nitrous acid and 2-methylpentane was
exposed to artificial sunlight (λ = 300–450 nm), acetone, propionaldehyde, peroxyacetal nitrate,
peroxypropionyl nitrate, and possibly two isomers of hexyl nitrate and propyl nitrate formed as
products (Cox et al., 1980).
Based on a photooxidation rate constant of 5.6 x 10
-12 cm
3/molecule?sec for the reaction of 2-
methylpentane and OH radicals, the atmospheric lifetime is 25 h (Altshuller, 1991).
Chemical/Physical: Complete combustion in air yields carbon dioxide and water vapor. 2-
Methylpentane will not hydrolyze because it does not contain a hydrolyzable functional group.
純化方法
Purify it by azeotropic distillation with MeOH, followed by washing out the MeOH with water, drying (CaCl2, then sodium), and distilling it. [Forziati et al. J Res Nat Bur Stand 36 129 1946.]
