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, kāore e memeha i roto i te etanoru, ā, he memeha noa iho 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 putanga nui rawa atu o te ao. Ko te umanga ethylene te uho o te umanga petrochemical.EtirenaNeke atu i te 75% o ngā hua matū hinu te nui o ngā hua, ā, he tūranga nui kei roto i te ōhanga o te motu. E whakaarohia ana e te ao ko te hanga ethylene tētahi o ngā tohu nui hei ine i te taumata whanaketanga o te umanga matū hinu o tētahi whenua. He rauemi mata matua nui te ethylene, he matū waro nui, e whakamahia ana i te nuinga o te wā i roto i te hanga polyethylene, te rapa ethylene propylene, te polyvinyl chloride, me ētahi atu. Ko te ethylene tētahi o ngā rauemi mata matua mō te umanga matū hinu. 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, te ethylene oxide, te ethylene glycol, te 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 chloroethylene, chloroethane, bromoethane, me ētahi atu. Ka whakamahia hoki te ethylene hei hau paerewa mō ngā taputapu tātari i roto i ngā umanga matū hinu; whakamahia hei hau pakari e pai ana ki te taiao mō ngā hua pēnei i te karaka piko, te tāne, te panana, me ētahi atu; whakamahia i roto i te hanganga rongoā me ngā rauemi hangarau teitei; whakamahia i roto i te hanga karāhe motuhake mō te umanga motuka; whakamahia hei whakamatao, inā koa i roto i ngā tipu wai LNG. Ngā whakatūpato rokiroki: Penapena ki 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 penapena motuhake mai i ngā waikura me ngā halogen, ā, karohia te rokiroki whakauru. Whakamahia ngā rama ātete-pahūtanga me ngā whakaurunga hauhautanga. Kāore e whakaaetia te whakamahi i ngā taputapu me ngā taputapu miihini e ngāwari ana ki te mura. Me whai taputapu maimoatanga ohorere turuturu te wāhi rokiroki.
