The chemical chilinganizo ndiC2H4. Ndi mankhwala opangira ulusi wopangira, mphira wopangira, mapulasitiki opangira (polyethylene ndi polyvinyl chloride), ndi ethanol (mowa). Amagwiritsidwanso ntchito popanga vinyl chloride, styrene, ethylene oxide, acetic acid, acetaldehyde, ndi zophulika. Itha kugwiritsidwanso ntchito ngati chopangira zipatso ndi ndiwo zamasamba. Ndi hormone yotsimikiziridwa ya zomera.

Ethylenendi imodzi mwa mankhwala aakulu kwambiri padziko lonse lapansi. Makampani a ethylene ndiye maziko amakampani a petrochemical. Zogulitsa za ethylene zimaposa 75% yazinthu zamafuta a petrochemical ndipo zimakhala ndi gawo lofunikira pazachuma chadziko. Dziko lapansi lagwiritsa ntchito kupanga ethylene ngati chimodzi mwazizindikiro zofunika kuyesa kukula kwamakampani amafuta amafuta mdziko muno.

Minda yofunsira

1. Chimodzi mwazinthu zofunikira kwambiri pamakampani a petrochemical.

Kumbali ya zipangizo zopangira, zimagwiritsidwa ntchito kwambiri popanga polyethylene, vinyl chloride ndi polyvinyl kolorayidi, ethylbenzene, styrene ndi polystyrene, ndi mphira wa ethylene-propylene, etc.; ponena za kaphatikizidwe ka organic, amagwiritsidwa ntchito kwambiri popanga ethanol, ethylene oxide ndi ethylene glycol, acetaldehyde, acetic acid, propionaldehyde, propionic acid ndi zotumphukira zake ndi zina zofunika organic kupanga zopangira; pambuyo halogenation, akhoza kupanga vinilu kolorayidi, ethyl kolorayidi, ethyl bromide; pambuyo polima, imatha kutulutsa α-olefins, kenako ndikupanga ma alcohols apamwamba, alkylbenzenes, etc.;

2. Amagwiritsidwa ntchito makamaka ngati mpweya wokhazikika pazida zowunikira m'mabizinesi a petrochemical;

3. Ethyleneamagwiritsidwa ntchito ngati mpweya wochanga bwino wa zipatso monga malalanje a navel, ma tangerines, ndi nthochi;

4. Ethyleneimagwiritsidwa ntchito popanga mankhwala komanso kaphatikizidwe kazinthu zamakono.
