Examples of petrochemical in the following topics:
- 
Chemical Manufacturing- The raw starting materials are commonly from petrochemical sources (fractional distillation of crude oil produces a wide variety of valuable materials for the chemical industry) or can be extracted from nature.
- Basic chemicals, or "commodity chemicals" are a broad chemical category including polymers, bulk petrochemicals and intermediates, other derivatives and basic industrials, inorganic chemicals, and fertilizers.
- The majority of the raw materials for polymers come from petrochemical sources, or crude oil fractionation.
 
- 
Hydrogenation- In petrochemical processes, hydrogenation is used to saturate alkenes and aromatics, making them less toxic and reactive.
 
- 
Trihalides: Boron-Halogen Compounds- Boron trifluoride is used in the petrochemical industry as a catalyst.
 
- 
Types of Synthetic Organic Polymers- Polystyrene (PS) is an aromatic polymer made from the monomer styrene, a liquid petrochemical.
