Gasoline It is one of the most important light petroleum products obtained from the distillation and processing of crude oil. This substance is a mixture of Volatile hydrocarbons with different octane numbers and because High flammabilityIt plays a vital role in the transportation, energy, and some industrial and laboratory applications.
In addition to being used as a fuel, gasoline is also used in certain industries as Petroleum solvent is also used.

Types of gasoline and their densities
Gasoline density is one of the important parameters in Quality control, standardization and industrial application The table below shows the density range of gasoline types at different temperatures. 60°F It shows:
| Gasoline type | Minimum density at 60°F | Maximum density at 60°F |
|---|---|---|
| Regular gasoline | 0.70 | 0.75 |
| Super leaded gasoline | 0.72 | 0.77 |
| Super unleaded gasoline | 0.725 | 0.78 |
Main components of gasoline
Gasoline is a mixture of several hydrocarbon groups, each of which affects its performance:
| Hydrocarbon group | Role in gasoline |
|---|---|
| Paraffins | Improved combustion and reduced soot |
| Isoparaffins | Increasing octane number |
| Aromatics | Increased power and fuel energy |
| Naphthenes | Chemical stability |
