Haɗin Ethylene Oxide & Carbon Dioxide

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. Yawancin lokaci ana amfani da ethylene oxide-carbon dioxide (rabo na biyu shine 90:10) ko cakuda ethylene oxide-dichlorodifluoromethane, galibi ana amfani da su don lalata asibitoci da kayan aiki daidai. Ethylene oxide yana ƙonewa kuma yana fashewa, kuma abubuwan sinadaransa suna aiki sosai. Yana iya fuskantar ƙarin halayen buɗaɗɗen zobe tare da mahadi da yawa. Ba shi da sauƙi don jigilar kaya a kan nesa mai nisa, don haka yana da halaye masu ƙarfi na yanki. Kariyar ajiya: Ajiye a cikin ɗakin ajiya mai sanyi, mai iska. Ka nisantar da wuta da tushen zafi. Guji haske. Yanayin ajiya bai kamata ya wuce 30 ° C ba. Ya kamata a adana shi daban daga acid, alkalis, alcohols, da sinadarai masu cin abinci, kuma a guje wa ajiya mai gauraya. Yi amfani da fitilun da ke hana fashewa da wuraren samun iska. An haramta amfani da kayan aikin injiniya da kayan aikin da ke da saurin tartsatsi. Wurin ajiya ya kamata a sanye shi da kayan aikin jinya na gaggawa.

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. .
