Ethylene (C2H4) ethene For Fruit Ripening , Chemical Industry And For The Production Of Plastics.
Description:
1. A colorless flammable gaseous unsaturated hydrocarbon C2H4 that is found in coal gas, can be produced by pyrolysis of petroleum hydrocarbons, and occurs in plants functioning especially as a natural growth regulator that promotes the ripening of fruit
1. Physical properties
A divalent hydrocarbon group C2H4 derived from ethane
2. Test report
Ethylene should be used when combustible gas pressure relief valve (decompression table), and the detection of airtightness of the pipeline, the use of gas is strictly prohibited. Switch the gas valve when the action must be slow, no gas should be kept when the cylinder valve closed.
Used cylinders should be retained in accordance with the provisions of the residual pressure of more than 0.05MPa, flammable gas should be retained more than 0.2MPa residual pressure. All kinds of cylinders should be dedicated to the bottle, must be regularly carried out safety inspection.

Applications:
Ethylene is used in a range of industries and applications including:
Chemicals: 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.
Food & Beverages: An ethylene / nitrogen mixture supplied cylinders is used to control ripening of fruit, especially bananas. A concentration of a few ppm in the warehouse atmosphere is used. It is also used in agriculture to promote crop growth. In this application The gas is directly injected into the soil.
Glass: Ethylene is used in the production of specialty glass for the automotive industry (car glass).
Medical: Ethylene is used as an anaesthetic
Metal Fabrication: Ethylene is used as oxy-fuel gas in metal cutting, welding and high velocity thermal spraying
Refining: Ethylene is used as refrigerant, especially in LNG liquefaction plants.
Rubber & Plastics: Ethylene is used in the extraction of rubber.
