Isobutane, scientifically known as 2-methylpropane and identified by its CAS registry number 75-28-5, is a hydrocarbon gas that holds considerable importance across a spectrum of industrial applications. As an isomer of butane, its branched molecular structure imparts unique physical and chemical properties that differentiate it from its linear counterpart. At room temperature and atmospheric pressure, it exists as a colorless, odorless gas, typically supplied in high purity grades, often exceeding 99% for specialized applications.

The physical properties of Isobutane are critical to its functional roles. Its low boiling point, around -11.7°C (11°F), allows it to be easily liquefied under moderate pressure, facilitating storage and transportation as a liquefied gas. This characteristic is fundamental to its use as a refrigerant (R-600a) and as a component in aerosol propellants. Its high flammability requires careful handling and adherence to safety protocols, a common characteristic of light hydrocarbons.

Chemically, Isobutane is relatively stable but can participate in various reactions, most notably alkylation. Its primary industrial reaction involves alkylation with olefins like isobutylene to produce isooctane. This process is essential for enhancing the octane rating of gasoline, improving its anti-knock capabilities. The efficiency of this reaction depends heavily on the purity of the Isobutane used. Manufacturers often seek bulk suppliers that can guarantee consistent quality and supply chains for this vital chemical intermediate.

Isobutane is also a component of liquefied petroleum gas (LPG) and is found in natural gas and refinery streams. Its extraction and purification are key processes in the petrochemical industry. Understanding these applications helps in appreciating the broad industrial significance of Isobutane.
