Vinyylimono
Vinyylimono is a term sometimes used colloquially to refer to vinyl monohydride, also known as ethene or ethylene. Ethene is a simple hydrocarbon with the chemical formula C₂H₄. It is a colorless gas with a faintly sweet odor. Ethene is a fundamental building block in the petrochemical industry and is primarily produced by steam cracking of hydrocarbons. Its most significant application is in the production of polyethylene, the world's most common plastic. Polyethylene is used in a vast array of products, including packaging films, bottles, bags, and insulation. Ethene is also a precursor to other important chemicals such as ethylene oxide, which is used to produce ethylene glycol (antifreeze) and polyester fibers, and vinyl chloride, the monomer used to make polyvinyl chloride (PVC). In biological systems, ethene is a plant hormone that plays a role in processes such as fruit ripening, senescence, and abscission. While "vinyylimono" is not a standard chemical nomenclature, its likely origin stems from the "vinyl" group (CH₂=CH-) present in ethene, combined with "mono" to indicate a single molecule or perhaps a simplified reference to its fundamental nature as a monomer.
