Ifomula yekhemikhaliC2h4. Sisiseko semichiza esisiseko yemichiza yemichiza ye-Syntheetic, irabha yerabha ye-syntic, iplasitiki ye-polythylene kunye ne-polyvinyl chloride), kunye ne-ethanol (utywala). Ikwasetyenziselwa ukwenza i-vinyl chloride, istyrene, i-ithylene oxide, i-acetic acid, i-acetaldehyde, kunye neziqhushumbisi. Ingasetyenziselwa njengearhente yokuvuthwa kweziqhamo kunye nemifuno. Yihombo eliqingqiweyo lesityalo.

I-ithyleneyenye yezona mveliso zikhulu zehlabathi. Umzi-mveliso we-ethylene yeyona nto iphambili kumzi-mveliso wepetrochemical. I-Akhawunti yeMveliso ye-Ethylene engaphezulu kwe-75% yeemveliso zepetrochemical kwaye ihlale isikhundla esibalulekileyo kuqoqosho lukazwelonke. Umhlaba usebenzise imveliso ye-Ethylene njengomnye wezalathisi ezibalulekileyo zokulinganisa inqanaba lokuphuhliswa kweshishini le-petrochemical yelizwe.

Amasimiselo

I-1. Enye yezona zinto zisisiseko ziluhlaza okwenziwa kwishishini lepetrochemical.

Ngokwezinto zokwenziwa, isetyenziswa ngokubanzi kwimveliso ye-polythylene, i-vinyl pherviny ye-pheloviny evukelayo, i-Ethylbenzene, i-stytone kunye ne-polystyrene, i-polylystlene irabha, njl.; ngokwemigaqo ye-synthesic, isetyenziswe ngokubanzi kwi-ethanol, i-ethylene oxide ne-ethylene glycol, i-acetane ye-acetahyde, i-acetane-acid, i-propioldehyde, i-propidic acid i-orgacitic syntiction; Emva kweHallogation, inokuvelisa i-vinyl hloride, chloride ye-bromide, ye-Ethyl; Emva kwe-Polymerization, inokuvelisa i-olefins ye-olefins, emva koko ivelise iluphala oluphezulu, ialkylbenes, njl.;

2. Isetyenziselwa ikakhulu njengegesi esemgangathweni yokuhlalutya izixhobo kwi-petrochemical amashishini;

I-3. Eneleneneisetyenziselwa njengokuvuthwa okunobuhlobo okusingqongileyo ngeziqhamo ezinjengeNqaku zeNqaku, i-Taline, kunye neebhanana;

4. I-ithyleneisetyenziswa kwi-synthesical synthesical synthesic kunye ne-up tenthes ye-tekstis synthesis.
