What is a Octane?

Octane (chemical formula: C₈H₁₈) is a hydrocarbon belonging to the alkane group, existing as a liquid with either straight-chain or branched-chain structures. It is widely known as a component of gasoline and plays a significant role in combustion efficiency and engine performance. The "octane rating" of gasoline is a key indicator of its resistance to knocking, which is crucial for achieving efficient combustion in an engine. A higher octane rating means that the gasoline is more resistant to compression, reducing the likelihood of abnormal combustion (knocking) within the engine. This helps improve engine performance and can enhance fuel efficiency. Additionally, octane is chemically stable, highly volatile, and efficient as a fuel component.

Industrially, octane is also used in chemical synthesis, serving as an intermediate or additive in various chemical processes.
