Formula: C2H4
CAS No.: 74-85-1
EINECS No.:200-815-3
UN No.: UN1962
Purity: 99-100%
Dot Class: 2.1 flammable gas
Ethylene is a hydrocarbon which has the formula C₂H₄ or H₂C=CH₂. It is a colourless, flammable gas with a faint "sweet and musky" odour when pure. It is the simplest alkene. Ethylene is widely used in the chemical industry, and its worldwide production exceeds that of any other organic compound.
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
