Ethylene, refrigerated liquid (cryogenic liquid) appears as a pressurized liquid when shipped below 50 °F. Colorless with a sweet odor and taste. Vapors arising from the boiling liquid are lighter than air. Easily ignited. Not toxic but is a simple asphyxiant.

Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula C 2 H 4 or H 2 C=CH 2. It is a colourless, flammable gas with a faint "sweet and musky" odour when pure. [7] It is the simplest alkene (a hydrocarbon with carbon–carbon double bonds).

Ethylene or ethene is a chemical compound with two carbon atoms and four hydrogen atoms in each molecule. These molecules are put together with a double bond that makes it a hydrocarbon. It is very important in industry and has even been used in biology as a hormone. [1] It is also the most made chemical.

Ethylene (ET), a simple olefin, is an important synthetic reagent. It is also a plant hormone that regulates various physiological and developmental processes, such as ripening of fruit, abscission, senescence and responses to wounding in plants. Pd(II) and Ni(II)-based catalysts are reported to catalyze the polymerization of ET to afford high molecular weight polymers.
