Sulfuric acid, Nitrogen, Oxygen, Ethylene, Propylene are some of the examples of heavy chemicals in chemical industries.
Step-by-step explanation:
Sulfuric acid
- Removing impurities during refining of petroleum
- Removing metallic oxides prior to electroplating and metal galvanizing
- Removing water during chemical reactions
- Acting as a reactant in the manufacture of rayon and nitroglycerine
Nitrogen
- In the manufacture of steel and other metals
- In cooling concrete, which further improves the properties of the building material
- In freezing soggy ground, further making construction easier.
Ethylene (C₂H₄):
- To manufacture ethanol for industrial uses.
- To produce polyester
- To produce synthetic rubber
