2metilpentano

2-metilpentano, known in English as 2-methylpentane and sometimes called isohexane, is an isomer of hexane with the molecular formula C6H14. It is a branched aliphatic hydrocarbon and a component of many gasoline fractions produced during petroleum refining.

Its structure consists of a five-carbon main chain with a methyl substituent at the second carbon, giving the arrangement CH3-CH(CH3)-CH2-CH2-CH3. Among hexane isomers, 2-methylpentane is one of the two branched forms derived from a pentane backbone.

Physically, 2-methylpentane is a colorless liquid at room temperature. It has a molar mass of about 86.17 g/mol and a boiling point near 63 °C. Its density is around 0.66 g/cm3 at 20 °C. The substance is largely insoluble in water but mixes with many organic solvents, reflecting its nonpolar character. It is moderately volatile and flammable.

Production and applications: 2-methylpentane is obtained during the processing of crude oil and as part of refinery streams. It is used as a solvent in paints, coatings, adhesives, and cleaning formulations, and it can serve as a chemical intermediate in the synthesis of other hydrocarbons and industrial products.

Safety: 2-methylpentane is a flammable liquid with vapors capable of forming explosive mixtures with air. It should be handled with adequate ventilation, away from ignition sources, and with appropriate personal protective equipment. Exposure may affect the nervous system and respiratory tract; spills should be contained and disposed of according to local regulations.
