(muD) Iso-Octane

The Mean Density of Iso-Octane is 691.9 kg/m³. At standard temperature and pressure (STP), which is typically defined as 0 degrees Celsius (32 degrees Fahrenheit) and 1 atmosphere (101.3 kilopascals) of pressure, the mean density of iso-octane is approximately 691 kilograms per cubic meter (kg/m³) or 0.691 grams per cubic centimeter (g/cm³). This value may vary slightly depending on the specific conditions and purity of the iso-octane sample.

Iso-Octane

Iso-octane, also known as 2,2,4-trimethylpentane, is a chemical compound with the molecular formula C8H18. It is a branched-chain alkane belonging to the group of hydrocarbons known as octanes. The "iso" prefix in its name indicates that it has an isomeric structure, meaning its carbon atoms are arranged differently from those in normal octane (n-octane), which has a linear structure.

Iso-octane is a colorless liquid with a gasoline-like odor. It is highly flammable and is commonly used as a reference standard in the octane rating of gasoline. The octane rating measures the anti-knock properties of gasoline, with higher octane numbers indicating a fuel that is less prone to causing knocking or pinging in internal combustion engines.

In addition to its role as a reference standard, iso-octane is also used in laboratory settings, as a solvent, and in some industrial applications. Its properties, including its high octane rating and low reactivity, make it valuable in various industries, particularly in the automotive and petroleum sectors.
