Ethylene cas 74-85-1
Ethylene se yon konpoze ki konpoze de de atòm kabòn ki konekte pa yon kosyon doub ak kat atòm idwojèn . ethylene egziste nan sèten tisi ak ògàn nan plant yo ak se konvèti nan metionin anba kondisyon ase oksijèn .}
Ethylene is a basic chemical raw material for synthetic fibers, synthetic rubber, synthetic plastics (polyethylene and polyvinyl chloride), and synthetic ethanol (alcohol). It is also used to make vinyl chloride, styrene, ethylene oxide, acetic acid, acetaldehyde, ethanol and Eksplozif . Li kapab tou itilize kòm yon ajan matrité pou fwi ak legim . Li se yon òmòn plant pwouve .
Ethylene is one of the world's largest chemical products. The ethylene industry is the core of the petrochemical industry. Ethylene products account for more than 75% of petrochemical products and occupy an important position in the national economy. The world has used ethylene production as one of the important indicators to measure the level of development of a country's Petrochemical Industry .
Physiological effects are: triple reaction, promoting fruit ripening, promoting leaf senescence, inducing adventitious roots and root hairs, breaking the dormancy of plant seeds and buds, inhibiting flowering of many plants (but inducing and promoting flowering of pineapples and plants of the same genus), and changing the direction of sexual differentiation of flowers in the early stages of flower development in plants with male and female flè .
Nòmalman, ethylene se yon gaz san koulè, yon ti kras odè ak yon dansite nan 1 . 256g/L, ki se yon ti kras mwens pase dansite nan lè . li se solubl nan dlo ak fasil soluble nan solvants òganik tankou tetrachlorid kabòn.
Aparans ak pwopriyete: gaz san koulè ak yon ti odè inik nan idrokarbur . Yon ti kantite lajan nan ethylene gen yon gou bouke anpil dous .

Ethylene se yon òmòn gaz . tisi ki gen matirite lage mwens ethylene, pandan y ap meristèm, grenn jèminasyon, flè meprizan ak fwi nan pwosesis la nan lèt pwodwi plis ethylene . li egziste nan fwi ki gen matirite, nod yo ak Senescent {{ Efè "(ki se, akimilasyon nan ethylene ka estimile plis pwodiksyon ethylene) .
Nan kondisyon sa yo negatif nan sechrès, polisyon nan lè a, eksitasyon mekanik, estrès chimik, maladi, elatriye ., ethylene a nan kò a nan plant ogmante plizyè fwa oswa plizyè douzèn fwa . etilèn sa a ki te pwodwi pa kò a plant ki anba kondisyon yo rele etilèn oswa estrès ethylene (lsy ethen (ethylene estrès (ethylene estrès (ethylene ethylene (ethylene estrès (ethylene estrès (ethylene estrès (ethylene estrès etilèn (ethylene estrès (ethylene estrès etilèn (ethylene estrès (ayen etilèn (ethylene estrès (ethylene {
