Ethylene Oxide (ETO)

Siffofin fasaha

Ethylene oxide yana daya daga cikin mafi sauki ethers cyclic. Yana da mahaɗin heterocyclic. Tsarin sinadaransa shine C2H4O. Carcinogen ne mai guba kuma wani muhimmin samfurin petrochemical. Abubuwan sinadaran ethylene oxide suna aiki sosai. Yana iya jurewa ƙarin halayen buɗaɗɗen zobe tare da mahadi da yawa kuma yana iya rage nitrate na azurfa. Yana da sauƙi don yin polymerize bayan an yi zafi kuma zai iya bazuwa a gaban gishirin ƙarfe ko oxygen. Ethylene oxide ruwa ne mara launi kuma bayyananne a ƙananan zafin jiki, da iskar gas mara launi tare da ƙamshi na ether a yanayin zafi na al'ada. Matsin tururi na iskar gas yana da girma, yana kaiwa 141kPa a 30 ° C. Wannan babban tururin matsa lamba yana ƙayyade ƙarfin shigar da epoxy mai ƙarfi a lokacin fumigation na ethane da disinfection. Ethylene oxide yana da tasirin bactericidal, ba ya lalacewa ga karafa, ba shi da wari mai saura, kuma yana iya kashe ƙwayoyin cuta (da endospores), ƙwayoyin cuta da fungi, don haka ana iya amfani da shi don lalata wasu abubuwa da kayan da ba za su iya jure wa yanayin zafi mai zafi ba. . . Ethylene oxide shine maganin sinadarai na ƙarni na biyu bayan formaldehyde. Har yanzu yana ɗaya daga cikin mafi kyawun magungunan sanyi. Hakanan shine manyan fasahohin haifuwa masu ƙarancin zafin jiki guda huɗu (ƙananan plasma mai zafi, tururi mai ƙarancin zafin jiki na formaldehyde, ethylene oxide). , Glutaraldehyde) mafi mahimmancin memba. Ethylene oxide kuma an fi amfani da shi don yin wasu sauran kaushi daban-daban (kamar cellosolve, da dai sauransu), diluents, non-ionic surfactants, roba detergents, antifreeze, disinfectants, tougheners da plasticizers, da dai sauransu. Domin ethylene oxide yana da ƙonewa kuma yana da kewayon tattara abubuwa masu fashewa a cikin iska, wani lokaci ana amfani da shi azaman ɓangaren mai na bama-bamai masu fashewa. Abubuwan konewa masu cutarwa sune carbon monoxide da carbon dioxide. Ana amfani da yawancin ethylene oxide don yin wasu sinadarai, musamman ethylene glycol. Ethylene oxide yana ƙonewa kuma yana fashewa, kuma ba shi da sauƙi don jigilar kaya a kan nesa mai nisa, don haka yana da halayen yanki mai ƙarfi.

Aikace-aikace:

① Bakarawa:

Ethylene oxide yana da tasirin bactericidal, ba ya lalacewa ga karafa, ba shi da wari mai saura, kuma yana iya kashe ƙwayoyin cuta (da endospores), ƙwayoyin cuta da fungi, don haka ana iya amfani da shi don lalata wasu abubuwa da kayan da ba za su iya jure wa yanayin zafi mai zafi ba. .

② asali sinadaran albarkatun kasa:

Ethylene oxide galibi ana amfani dashi don yin ethylene glycol (raw material don polyester fiber), kayan wanka na roba, abubuwan da ba na ion ba, antifreeze, emulsifiers, da samfuran ethylene glycol. Ana kuma amfani da ita wajen samar da robobi, man shafawa, roba da robobi da sauransu.
