I-Ethylene (C2H4)

Iiparameter zobugcisa

Phantsi kweemeko eziqhelekileyo, i-ethylene yigesi engenambala, evuthayo kancinci enobunzima obuyi-1.178g/L, exinene kancinci kunomoya. Ayinyibiliki emanzini, ayinyibiliki kangako kwi-ethanol, kwaye inyibilika kancinci kwi-ethanol, ii-ketones, kunye ne-benzene. , Inyibilika kwi-ether, inyibilika lula kwizinyibilikisi ze-organic ezifana ne-carbon tetrachloride.I-ethyleneyenye yeemveliso zeekhemikhali ezinemveliso enkulu ehlabathini. Ishishini le-ethylene liphambili kwishishini le-petrochemical.I-ethyleneIimveliso zingaphezulu kwe-75% yeemveliso zepetrochemical kwaye zithatha indawo ebalulekileyo kuqoqosho lwelizwe. Ihlabathi liye lajonga ukuveliswa kwe-ethylene njengenye yeempawu ezibalulekileyo zokulinganisa inqanaba lophuhliso lweshishini lepetrochemical lelizwe. I-ethylene sisixhobo esibalulekileyo sekhemikhali yendalo, esisetyenziswa kakhulu ekuveliseni i-polyethylene, irabha ye-ethylene propylene, i-polyvinyl chloride, njl. I-ethylene yenye yezona zinto zisisiseko kwishishini lepetrochemical. Ngokuphathelele izinto zokwenziwa, isetyenziswa kakhulu ekuveliseni i-polyethylene, i-vinyl chloride, njl.; ngokubhekisele kwi-organic synthesis, isetyenziswa kakhulu ekuhlanganiseni i-ethanol, i-ethylene oxide, i-ethylene glycol, i-acetaldehyde, kunye ne-propylene. Iindidi ezahlukeneyo zezinto ezisisiseko ze-organic synthesis ezifana ne-aldehydes kunye ne-derivatives yazo; ngokusebenzisa i-halogenation, inokuvelisa i-chloroethylene, i-chloroethane, i-bromoethane, njl. I-ethylene ikwasetyenziswa kakhulu njengegesi eqhelekileyo yezixhobo zohlalutyo kumashishini epetrochemical; isetyenziswa njengegesi yokuvuthwa enobuhlobo nokusingqongileyo kwiziqhamo ezifana nee-navel orenji, iitangerines, iibhanana, njl.njl.; isetyenziswa ekuhlanganiseni amayeza kunye nezixhobo zobugcisa obuphezulu; isetyenziswa ekuveliseni iglasi ekhethekileyo kwishishini leemoto; isetyenziswa njengesiqandisi, Ingakumbi kwizityalo ze-LNG liquefaction. Amanyathelo okugcina: Gcina kwindawo yokugcina izinto epholileyo, enomoya opholileyo. Gcina kude nomlilo kunye nemithombo yobushushu. Ubushushu bokugcina akufuneki budlule kwi-30°C. Kufuneka igcinwe ngokwahlukileyo kwii-oxidants kunye nee-halogens, kwaye uphephe ukugcinwa okuxutyiweyo. Sebenzisa izibane ezikhusela ukuqhuma kunye nezixhobo zokungenisa umoya. Akuvumelekanga ukusebenzisa izixhobo zoomatshini kunye nezixhobo ezinokuba neentlantsi. Indawo yokugcina kufuneka ixhotyiswe ngezixhobo zonyango olungxamisekileyo oluvuzayo.
