Hydrocarbons In Crude Oils

Posted by Mr Wellhead Labels:

The major classes of hydrocarbons in crude oils include:

  1. Paraffins
  2. Aromatics
  3. Napthenes or Cycloalkanes
  4. Alkenes
  5. Dienes and Alkynes
There are two things that make hydrocarbons exciting to chemists:

  • Hydrocarbons contain a lot of energy. Many of the things derived from crude oil like gasoline, diesel fuel, paraffin wax and so on take advantage of this energy.
  • Hydrocarbons can take on many different forms. The smallest hydrocarbon is methane (CH4), which is a gas that is a lighter than air. Longer chains with 5 or more carbons are liquids. Very long chains are solids like wax or tar. By chemically cross-linking hydrocarbon chains you can get everything from synthetic rubber to nylon to the plastic in tupperware. Hydrocarbon chains are very versatile!
