Ifomula yekhemikhali yileC2H4. Yinto esisiseko yekhemikhali esetyenziswa kwiifayibha zokwenziwa, irabha yokwenziwa, iiplastiki zokwenziwa (i-polyethylene kunye ne-polyvinyl chloride), kunye ne-ethanol yokwenziwa (utywala). Ikwasetyenziselwa ukwenza i-vinyl chloride, i-styrene, i-ethylene oxide, i-acetic acid, i-acetaldehyde, kunye neziqhushumbisi. Ingasetyenziswa njenge-arhente yokuvuthwa kweziqhamo nemifuno. Yi-hormone yezityalo eqinisekisiweyo.

I-ethyleneyenye yezona mveliso zinkulu zeekhemikhali kwihlabathi. Ishishini le-ethylene liphambili kwishishini le-petrochemical. Iimveliso ze-ethylene zenza ngaphezulu kwe-75% yeemveliso ze-petrochemical kwaye zibambe indawo ebalulekileyo kuqoqosho lwelizwe. Ihlabathi lisebenzise imveliso ye-ethylene njengenye yeempawu ezibalulekileyo zokulinganisa inqanaba lophuhliso lweshishini le-petrochemical yelizwe.

Amasimi esicelo

1. Enye yezona zinto zisisiseko kwishishini le-petrochemical.

Ngokuphathelele izinto zokwenziwa, isetyenziswa kakhulu ekuveliseni i-polyethylene, i-vinyl chloride kunye ne-polyvinyl chloride, i-ethylbenzene, i-styrene kunye ne-polystyrene, kunye nerabha ye-ethylene-propylene, njl.njl.; ngokubhekisele kwi-organic synthesis, isetyenziswa kakhulu ekuhlanganiseni i-ethanol, i-ethylene oxide kunye ne-ethylene glycol, i-acetaldehyde, i-acetic acid, i-propionaldehyde, i-propionic acid kunye nezinto eziphuma kuyo kunye nezinye izinto ezisisiseko ze-organic synthetic raw; emva kwe-halogenation, inokuvelisa i-vinyl chloride, i-ethyl chloride, i-ethyl bromide; emva kwe-polymerization, inokuvelisa i-α-olefins, ize emva koko ivelise ii-alcohols eziphezulu, i-alkylbenzenes, njl.njl.;

2. Isetyenziswa kakhulu njengegesi eqhelekileyo kwizixhobo zohlalutyo kumashishini e-petrochemical;

3. Ei-thyleneisetyenziswa njengegesi yokuvuthwa enobuhlobo nokusingqongileyo kwiziqhamo ezifana nee-navel orenji, iitangerines, kunye neebhanana;

4. I-ethyleneisetyenziswa ekuqulunqweni kwamayeza kunye nasekuqulunqweni kwezinto zobugcisa obuphezulu.
