ethylene (H2C=CH2), the simplest of the organic compounds known as alkenes, which contain carbon-carbon double bonds. It is a colourless, flammable gas having a sweet taste and odour. Natural sources of ethylene include both natural gas and petroleum; it is also a naturally occurring hormone in plants, in which it inhibits growth and promotes leaf fall, and in fruits, in …
Chemical Economics Handbook. Published February 2022. Ethylene is primarily a petrochemically derived monomer used as a feedstock in the manufacture of plastics, fibers, and other organic chemicals that are ultimately consumed in the packaging, transportation, and construction industries, as well as many other industrial and consumer markets.
Ethylene quality worldwide is matched to customer requirements; no single chemical-grade ethylene exists. However, ethylene content normally exceeds 99.9 wt%. The reason for variation in ethylene specifiions is due to the use of ethylene in downstream processes that differ in sensitivity to impurities in ethylene, due to different alyst systems being used.
L''éthylène est une hormone qui inhibe la floraison sauf chez certaines espèces comme le manguier, chez lequel on synchronise la floraison des fruits en apportant de l''éthylène sur l''arbre. L''éthylène peut changer la nature des organes floraux. Chez les espèces monoïques, c''est une hormone féminisante.

Ethylene (IUPAC name: ethene) 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.[6] It is the simplest alkene (a hydrocarbon with carbon-carbon double bonds). Ethylene is widely used in the chemical industry, and its worldwide production (over 150 million
