Hydrocarbons, being compounds made of only carbon and hydrogen, are incredibly versatile. Their uses vary depending on whether they are alkanes, alkenes, alkynes, or aromatic hydrocarbons. Here’s a detailed overview:
1. Fuels
- Alkanes: Methane, propane, butane, and gasoline components are burned for energy.
- Coal and petroleum derivatives: Used for electricity generation and heating.
- Jet fuel and diesel: Mixtures of higher alkanes.
2. Industrial Feedstock / Raw Materials
- Alkenes: Ethene and propene are used to produce plastics (polyethylene, polypropylene), synthetic rubber, and chemicals like ethanol, ethylene glycol, and acetone.
- Aromatic hydrocarbons: Benzene, toluene, and xylene are precursors for dyes, pharmaceuticals, and polymers.
3. Lubricants and Waxes
- Long-chain alkanes: Paraffin wax, mineral oils, and lubricating oils for machinery.
4. Solvents
- Alkanes and aromatic hydrocarbons: Hexane, benzene, and toluene dissolve oils, greases, and paints.
5. Household Products
- Propane and butane: Used in lighters and portable stoves.
- Paraffin wax: Candles and waterproof coatings.
6. Petrochemicals and Synthetic Materials
- Plastics: Polyethylene, polypropylene, PVC (from hydrocarbons).
- Synthetic fibers: Nylon and polyester originate from hydrocarbon derivatives.
- Detergents and surfactants: Alkylbenzenes and other hydrocarbons.
7. Pharmaceuticals
- Hydrocarbons as intermediates: Benzene derivatives are essential in drug synthesis.
8. Special Uses
- Cryogenic liquids: Liquid methane and propane for refrigeration.
- Rocket fuel: Some hydrocarbons are used in liquid-fueled rockets.
