Eterine (C2H4)

Ngā tawhā hangarau

I raro i ngā āhuatanga noa, he hau mura te etilena, kāore he tae, he kakara paku, ā, ko tōna matotoru he 1.178g/L, he iti ake te matotoru i te hau. Kāore e memeha i roto i te wai, he uaua ki te memeha i roto i te etanoru, ā, he iti te memeha i roto i te etanoru, ngā ketone, me te benzene. , Ka memeha i roto i te etera, ka ngawari te memeha i roto i ngā whakarewa waro pēnei i te waro tetrachloride.EtirenaKo tētahi o ngā hua matū me te whakaputanga nui rawa atu o te ao. Ko te umanga ethylene te uho o te umanga petrochemical. Neke atu i te 75% o ngā hua petrochemical ngā hua ethylene, ā, he tūranga nui kei roto i te ōhanga o te motu. Kua whakaarohia e te ao ko te hanga ethylene tētahi o ngā tohu nui hei ine i te taumata whanaketanga o te umanga petrochemical o tētahi whenua. He rauemi mata matū waro nui te ethylene, e whakamahia ana i roto i te hanga polyethylene, te rapa ethylene propylene, te polyvinyl chloride, me ētahi atu. Ko te ethylene tētahi o ngā rauemi mata tino taketake mō te umanga petrochemical. Mō ngā rauemi hangai, he whānui te whakamahinga i roto i te hanga polyethylene, te vinyl chloride, me ētahi atu; mō te hanga waro, he whānui te whakamahinga i roto i te hanga ethanol, ethylene oxide, ethylene glycol, acetaldehyde, me te propylene. He maha ngā rauemi mata hanga waro taketake pērā i ngā aldehydes me ō rātou hua; Mā te halogenation, ka taea te whakaputa i te chloroethylene, te chloroethane, te bromoethane, me ētahi atu. Ko te ethylene te mea e whakamahia nuitia ana hei hau paerewa mō ngā taputapu tātari i roto i ngā umanga petrochemical; hei hau whakamātao taiao mō ngā hua pēnei i te karaka navel, te tangerines, te panana, me ētahi atu; hei hanga rongoā me ngā rauemi hangarau teitei; hei hanga karāhe motuhake mō te umanga motuka; hei whakamatao, inā koa i roto i ngā tipu wai LNG. Ngā whakatūpato rokiroki: Rokiroki i roto i te whare putunga hauhautanga, hauhautanga. Puritia kia matara atu i te ahi me ngā pūtake wera. Kaua te pāmahana rokiroki e neke ake i te 30°C. Me rongoa motuhake mai i ngā waikura me ngā halogens, ā, karohia te rokiroki whakauru. Whakamahia ngā rama me ngā whakaurunga hauhautanga ātete-pahūtanga. Kāore e whakaaetia te whakamahi i ngā taputapu miihini me ngā taputapu e ngawari ana ki te mura. Me whai taputapu maimoatanga ohorere turuturu te wāhi rokiroki.
