isobutaani

Isobutaani, also known as 2-methylpropane, is a branched-chain alkane with the chemical formula (CH3)2CHCH3. It is a structural isomer of n-butane. Isobutaane is a colorless gas at room temperature and pressure, with a faint gas-like odor. It is highly flammable.

Isobutaane is a component of liquefied petroleum gas (LPG), often mixed with n-butane and propane. It is used as a propellant in aerosol cans, a refrigerant, and a fuel. In the petrochemical industry, isobutane is a feedstock for producing other chemicals, such as isobutylene, which is used in the production of synthetic rubber and plastics. It can also be used as a component in gasoline blending to increase octane rating.

The production of isobutane primarily occurs through the refining of crude oil and natural gas processing. It can be separated from other hydrocarbon components through distillation and other separation techniques. Isobutaane is also produced via the isomerization of n-butane. Environmentally, isobutane is considered a greenhouse gas, though its contribution is less significant than that of some other hydrocarbons. Its flammability requires careful handling and storage to prevent accidents.
