Ethylene Gas C2H4
Ethylene gas provided by DSW is available in different purity grades and concentrations to meet the specific requirements of diverse industries.
DSW has in-house laboratory equipment to check the purity and concentration levels.
Ethylene is majorly used in polymerization and then to make plastics of different types and grades

Process
Ethylene is produced by passing ethyl alcohol vapours over dehydrating catalysts at 360-470 °C. The pyrolysis of ethane may also produce it.
The cracking of petroleum is another source.
Applications of Ethylene Gas
Ethylene is the starting material for several industrial syntheses. It is employed as an intermediate in the chemical industry and for the production of plastics.
Ethylene C2H4 Gas is employed for the production of:
acetaldehyde
acetic acid
chloroethane
chloroethene (vinyl chloride)
dichloroethane
1,1-dichloroethene (vinylidene chloride)
epoxyethane (ethylene oxide)
ethanediol (ethylene glycol)
ethanol
ethoxyethane
ethylbenzene
phenylethene (styrene)
polychloroethene (polyvinyl chloride)
polyethene
propanoic acid
tetraethyl lead
trichloroethane
Ethylene gas is used as a component in calibration gases for the automotive, gas, oil as well as chemical industry.
Ethylene may be employed for welding and cutting but is not used for industrial purposes.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.
Uses of Ethylene Gas
- Ethylene is used in the manufacturing of alcohol.
- Used in the manufacturing of polyethylene.
- Used in promoting senescence.
- Used to produce fabricated plastics.
- Used as a herbicide.
- Used as a curing agent for tobacco.
- Used as a refrigerant.
- Used as an anaesthetic.
- Used to accelerate the ripening of fruits commercially.
- Used in welding metals.
Because of flammability considerations, it is strongly recommended to use a mixture of ethene in nitrogen in this application.
Ethylene 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 anaesthetic (in the US).
It is used as a refrigerant, especially in the petrochemical industry. It has the ASHRAE number R-1150.
