DSW supplies ethylene in various purities and concentrations. Package options range from small cylinders to bulk ISO containers for your convenience.
Ethylene is produced by passing ethyl alcohol vapors over dehydrating catalysts at 360-470 °C. The pyrolysis of ethane may also produce it.
The cracking of petroleum is another source.
Ethylene is the starting material for several industrial syntheses. It is employed as an intermediate in the chemical industry and for producing plastics.
Ethylene C2H4 Gas is employed for the production of:
chloroethene (vinyl chloride)
1,1-dichloroethene (vinylidene chloride)
epoxyethane (ethylene oxide)
ethanediol (ethylene glycol)
polychloroethene (polyvinyl chloride)
Ethylene gas is used as a component in calibration gases for the automotive, gas, oil, and chemical industries.
C2H4 may be employed for welding and cutting but is not used for this purpose industrially.
Ethylene supplied in cylinders is used for controlled ripening of fruit, especially bananas. A concentration of a few ppm in the warehouse atmosphere is used.
Because of flammability considerations, it is strongly recommended to use a mixture of ethene in nitrogen in this application.
C2H4 has also been used in agriculture to promote crop growth: in this case, the gas is injected directly into the soil.
Ethylene is still used as an anesthetic (in the US).
It is used as a refrigerant, especially in the petrochemical industry. It has the ASHRAE number R-1150.
