2-methylpentane Chemical Properties,Usage,Production

Chemical Properties

colourless liquid

Chemical Properties

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.

Physical properties

Clear, colorless, very flammable liquid with an odor similar to hexane. An odor threshold concentration of 8.9 ppmv was reported by Nagata and Takeuchi (1990).

Uses

Organic synthesis, solvent.

Uses

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.

Uses

2-Methylpentane is mainly used in studies involving the functionalization of aliphatic C–H bonds using different carbene insertion processes to form C–H insertion products. The metal-free Ritter-type amination reaction of tertiary C–H bond using iodic acid as an oxidant in the presence of N-hydroxyphthalimide has also been reported.

Definition

ChEBI: 2-Methylpentane is an alkane.

Production Methods

Isohexane is manufactured by fractional distillation of gasoline derived from crude oil or liquid product derived from natural gas.

General Description

Watery liquid with a gasoline-like odor, Floats on water. Produces an irritating vapor.

Air & Water Reactions

Highly flammable.

Reactivity Profile

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.

Hazard

Flammable, dangerous fire risk, reacts vig-orously with oxidizing materials.

Health Hazard

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.

Source

Schauer et al. (1999) reported 2-methylpentane in a diesel-powered medium-duty truck exhaust at an emission rate of 930 μg/km.
A constituent in gasoline. Harley et al. (2000) analyzed the headspace vapors of three grades of unleaded gasoline where ethanol was added to replace methyl tert-butyl ether. The gasoline vapor concentrations of 2-methylpentane in the headspace were 9.3 wt % for regular grade, 9.8 wt % for mid-grade, and 10.4 wt % for premium grade.
Schauer et al. (2001) measured organic compound emission rates for volatile organic compounds, gas-phase semi-volatile organic compounds, and particle-phase organic compounds from the residential (fireplace) combustion of pine, oak, and eucalyptus. The gas-phase emission rate of 2-methylpentane was 8.6 mg/kg of pine burned. Emission rates of 2-methylpentane were not measured during the combustion of oak and eucalyptus.
California Phase II reformulated gasoline contained 2-methylpentane at a concentration of 36.9 g/kg. Gas-phase tailpipe emission rates from gasoline-powered automobiles with and without catalytic converters were 6.31 and 827 mg/km, respectively (Schauer et al., 2002).
Reported as an impurity (0.1 wt %) in 99.0–99.7 wt % 2,3-dimethylbutane (Chevron Phillips, 2004).

Environmental Fate

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 cm3/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.

Purification Methods

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.]

Toxics Screening Level

The initial threshold screening level (ITSL) for 2-methylpentane is 17,600 μg/m3 based on an 8 hr averaging time.
