2-methylpentane Chemical Properties,Uses,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.]
