2-メチルヘキサン 化学特性,用途語,生産方法
外観
無色～ほとんど無色, 澄明の液体
溶解性
水に不溶。エタノール, 有機溶媒に易溶。アセトンに極めて溶けやすく、エタノールに溶け、水にほとんど溶けない。
用途
機器分析用炭化水素異性体標準。
化学的特性
clear colorless liquid
物理的性質
Clear, colorless, flammable, watery liquid with an odor similar to pentane, 2-methylpentane, 3-
methylpentane, hexane, and 3-hexane. An odor threshold concentration of 420 ppb
v was reported
by Nagata and Takeuchi (1990).
使用
2-Methylhexane is mainly used as a model
iso-alkane in studies relating to
iso-alkane oxidation, vapor-liquid phase equilibria of heptane isomers and catalytic cracking.
危険性
Flammable, dangerous fire risk, explosivelimits in air 1–6%.
環境運命予測
Biological. Riser-Roberts (1992) reported 2- and 5-methylhexanoic acids as metabolites by the
microorganism Pseudomonas aeruginosa.
Photolytic. Based on a reported photooxidation reaction rate constant of 6.80 x 10
-12
cm
3/molecule?sec with OH radicals, the half-life of 2-methylhexane is 25 h (Altshuller, 1990).
Chemical/Physical. Complete combustion in air produces carbon dioxide and water vapor. 2-
Methylhexane will not hydrolyze because it does not contain a hydrolyzable functional group.
純化方法
Purify it by azeotropic distillation with MeOH, then wash it with water (to remove the MeOH), dry it over type 4A molecular sieves and distil it. [Beilstein 1 IV 397.]
