How to Separate Kerosene and Gasoline Using Fractional Distillation

Learn the step-by-step process to separate kerosene and gasoline through fractional distillation based on their boiling points.

To separate kerosene and gasoline, use a technique called fractional distillation. Heat the mixture gradually; gasoline, with its lower boiling point (30-200°C), will evaporate first. Condense the gasoline vapor into a separate container. Kerosene, which has a higher boiling point (150-300°C), will remain until it reaches its boiling point and can be collected separately.

FAQs & Answers

  1. What is fractional distillation? Fractional distillation is a process used to separate a mixture of liquids based on their different boiling points by heating and condensing their vapors.
  2. Why can't kerosene and gasoline be separated by simple filtration? Because kerosene and gasoline are both liquids and miscible to some extent, simple filtration cannot separate them; fractional distillation is required.
  3. What are the boiling points of kerosene and gasoline? Gasoline boils between approximately 30–200°C, while kerosene boils between 150–300°C, allowing their separation by heating.
