Applications
Applications of ethylene include the following:
- Polymerization: polyethylene is the world’s more widely used plastic
- Oxidation: ethylene is oxidized to produce ethylene oxide, a key raw material in the production of surfactants and detergent by ethoxylation
- Halogenation and hydrohalogenation
- Alkylation: major chemical intermediates from the alkylation with ethylene is ethylbenzene
- Hydration: it is the major nonfermentative precursor to ethanol
- Oligomerization
- Hydroformylation: hydroformylation of ethylene results in propionaldehyde
