What is the difference between 95-octane gasoline and 92-octane gasoline?
1 Answers
95-octane gasoline and 92-octane gasoline differ in the ratio of isooctane and n-heptane: 95-octane gasoline contains 95% isooctane and 5% n-heptane, while 92-octane gasoline contains 92% isooctane and 8% n-heptane. Gasoline is a volatile, flammable liquid hydrocarbon mixture obtained from petroleum through distillation or cracking processes. At room temperature, gasoline appears as a colorless to pale yellow, easily flowing liquid that is poorly soluble in water and highly flammable, with a distillation range of 30°C to 205°C. It is primarily used as fuel, with key characteristics including volatility, stability, anti-knock properties, corrosiveness, and cleanliness.
