Cov tshuaj formula yogC2H4. Nws yog ib qho yooj yim chemical raw khoom rau hluavtaws fibers, hluavtaws roj hmab, hluavtaws plastics (polyethylene thiab polyvinyl chloride), thiab hluavtaws ethanol (cawv). Nws kuj yog siv los ua vinyl chloride, styrene, ethylene oxide, acetic acid, acetaldehyde, thiab explosives. Nws kuj tseem siv tau los ua tus neeg sawv cev ripening rau txiv hmab txiv ntoo thiab zaub. Nws yog ib qho pov thawj cog tshuaj hormones.

Ethyleneyog ib qho ntawm cov khoom siv tshuaj lom neeg loj tshaj plaws hauv ntiaj teb. Kev lag luam ethylene yog lub hauv paus ntawm kev lag luam petrochemical. Ethylene cov khoom lag luam suav txog ntau dua 75% ntawm cov khoom siv petrochemical thiab tuav txoj haujlwm tseem ceeb hauv kev lag luam hauv tebchaws. Lub ntiaj teb no tau siv ethylene ntau lawm ua ib qho ntawm cov cim tseem ceeb los ntsuas qib ntawm kev loj hlob ntawm ib lub teb chaws kev lag luam petrochemical.

Daim ntawv thov teb

1. Ib qho ntawm cov khoom siv tseem ceeb tshaj plaws rau kev lag luam petrochemical.

Hais txog cov khoom siv hluavtaws, nws tau siv dav hauv kev tsim cov polyethylene, vinyl chloride thiab polyvinyl chloride, ethylbenzene, styrene thiab polystyrene, thiab ethylene-propylene roj hmab, thiab lwm yam. Nyob rau hauv cov nqe lus ntawm organic synthesis, nws yog dav siv nyob rau hauv lub synthesis ntawm ethanol, ethylene oxide thiab ethylene glycol, acetaldehyde, acetic acid, propionaldehyde, propionic acid thiab nws cov derivatives thiab lwm yam organic synthetic raw khoom; Tom qab halogenation, nws muaj peev xwm tsim vinyl chloride, ethyl chloride, ethyl bromide; tom qab polymerization, nws tuaj yeem tsim α-olefins, thiab tom qab ntawd tsim cov cawv ntau dua, alkylbenzenes, thiab lwm yam;

2. Feem ntau yog siv los ua cov qauv roj rau cov cuab yeej tshuaj ntsuam xyuas hauv kev lag luam petrochemical;

3. Ecov thyleneyog siv los ua ib puag ncig tus phooj ywg ripening roj rau cov txiv hmab txiv ntoo xws li txiv kab ntxwv txiv kab ntxwv, tangerines, thiab txiv tsawb;

4. Ethyleneyog siv nyob rau hauv pharmaceutical synthesis thiab high-tech khoom synthesis.
