Transcript

  • 1. Products from Oil
    • By the end of the lesson you should be able to:
    • Describe how oil can be separated
    • Name some products of fractional distillation
    • Give the difference between organic and inorganic compounds
    • Give some properties of polymers and explain why they are useful
  • 2. Hydrocarbons and crude oil
    • Longer chains mean…
    • Less ability to flow
    • Less flammable
    • Less volatile
    • Higher boiling point
    Crude oil is a mixture of HYDROCARBONS (compounds made up of carbon and hydrogen). Some examples: Increasing length Ethane C C H H H H H H Butane C C H H H H H H C C H H H H
  • 3. Fractional distillation Crude oil can be separated by fractional distillation. The oil is evaporated and the hydrocarbon chains of different lengths condense at different temperatures: Fractions with low boiling points condense at the top Fractions with high boiling points condense at the bottom
  • 4. Important key points Difficult to dispose of, oil (from which plastics are made) is running out Disadvantages of plastic Properties of different plastics make them fit for certain jobs, e.g. durable Advantages of plastic Changes shape when heated, polymer chains can move about when heated Thermoplastic Long chains of molecules. E.g. Polythene Polymer Do not contain carbon. E.g. H 2 O, NaNO 3 Inorganic Contain carbon. E.g. CH 4 , CH 3 COOH Organic Explanation Key point
