I-Ethylene (C2H4)

Iiparamitha zobugcisa

Phantsi kweemeko eziqhelekileyo, i-ethylene yigesi engenambala, enevumba elincinane enokutsha enoxinzelelo lwe-1.178g/L, exinene kancinci kunomoya. Iphantse yanganyibiliki emanzini, ayinyibiliki kwi-ethanol, kwaye ayinyibiliki kancinane kwi-ethanol, iiketones, kunye nebenzene. , Inyibilika kwi-ether, i-soluble ngokulula kwizinyibilikisi eziphilayo ezifana ne-carbon tetrachloride.Ethyleneyenye yeemveliso zemichiza enemveliso enkulu ehlabathini. Ushishino lwe-ethylene lungundoqo kwishishini lepetrochemical.Ethyleneiimveliso zenza ngaphezu kwe-75% yeemveliso zepetrochemical kwaye zithatha indawo ebalulekileyo kuqoqosho lwesizwe. Ihlabathi liyithathele ingqalelo imveliso ye-ethylene njengenye yezalathisi ezibalulekileyo zokulinganisa inqanaba lophuhliso loshishino lwepetrochemical yelizwe. I-ethylene yinto ebalulekileyo ye-organic organic material esisiseko ekrwada, esetyenziswa ikakhulu kwimveliso ye-polyethylene, i-ethylene propylene irabha, i-polyvinyl chloride, njl njl. Ngokubhekiselele kwizinto zokwenziwa, isetyenziswa ngokubanzi kwimveliso ye-polyethylene, i-vinyl chloride, njl.; ngokwemigaqo ye-organic synthesis, isetyenziswa ngokubanzi kwi-synthesis ye-ethanol, i-ethylene oxide, i-ethylene glycol, i-acetaldehyde, kunye nepropylene. Iintlobo ngeentlobo zezinto ezisisiseko ze-organic synthesis ekrwada ezifana ne-aldehydes kunye nezinto eziphuma kuzo; ngokusebenzisa i-halogenation, inokuvelisa i-chlorethylene, i-chloroethane, i-bromoethane, njl. isetyenziswe njengegesi yokuvuthwa kokusingqongileyo kwiziqhamo ezinjengee-orenji zenkaba, iitangerines, iibhanana, njl.; isetyenziswe kwi-synthesis yamayeza kunye nezixhobo eziphezulu zobuchwepheshe; isetyenziswe kwimveliso yeglasi ekhethekileyo yoshishino lweemoto; isetyenziswe njengefriji, Ngokukodwa kwizityalo ze-LNG ze-liquefaction. Amanyathelo okhuseleko: Gcina kwindawo epholileyo, nengena umoya. Zigcine kude nomlilo kunye nemithombo yobushushu. Ubushushu bokugcina akufunekanga budlule kuma-30°C. Kufuneka igcinwe ngokwahlukileyo kwi-oxidants kunye ne-halogens, kwaye ugweme ukugcinwa okuxubileyo. Sebenzisa izibane ezingagqabhukiyo kunye nezixhobo zokungenisa umoya. Akuvumelekanga ukusebenzisa izixhobo zoomatshini kunye nezixhobo ezixhomekeke kwiintlantsi. Indawo yokugcina kufuneka ixhotyiswe ngezixhobo zonyango olungxamisekileyo oluvuzayo.
