Ethylene Oxide (ETO)

Nā palena ʻenehana

ʻO ka Ethylene oxide kekahi o nā ether cyclic maʻalahi. He hui heterocyclic ia. ʻO C2H4O kona ʻano kemika. He mea make kino make a he mea waiwai nui ka petrochemical. ʻO nā waiwai kemika o ka ethylene oxide he ikaika loa. Hiki iā ia ke hoʻohui i nā pane hoʻohui pū me nā pūhui he nui a hiki ke hōʻemi i ka nitrate kālā. He maʻalahi ka polymerize ma hope o ka wela a hiki ke decompose i mua o nā paʻakai metala a i ʻole ka oxygen. ʻO ka Ethylene oxide he wai waihoʻoluʻu a ʻalohilohi i ka haʻahaʻa haʻahaʻa, a he kinoea kala ʻole me ka ʻala ʻala etera i ka mahana maʻamau. He kiʻekiʻe ke kaomi mahu o ke kinoea a hiki i 141kPa ma 30°C. ʻO kēia kaomi mahu kiʻekiʻe e hoʻoholo i ka epoxy Ka mana komo ikaika i ka wā ethane fumigation a me ka disinfection. He hopena bactericidal ka Ethylene oxide, ʻaʻohe corrosive i nā metala, ʻaʻohe koena ʻala, a hiki ke pepehi i ka maʻi bacteria (a me kāna mau endospores), molds a me nā haʻi, no laila hiki ke hoʻohana ʻia e disinfect i kekahi mau mea a me nā mea hiki ʻole ke kū i ka disinfection wela kiʻekiʻe. . . ʻO ka Ethylene oxide ka lua o ka hanauna kemika disinfectant ma hope o formaldehyde. ʻO ia kekahi o nā disinfectant anu maikaʻi loa. ʻO ia hoʻi nā ʻenehana sterilization haʻahaʻa haʻahaʻa nui (plasma wela haʻahaʻa, mahu formaldehyde wela haʻahaʻa, ethylene oxide). , Glutaraldehyde) ka lālā nui loa. Hoʻohana nui ʻia ka Ethylene oxide e hana i nā ʻano solvents ʻē aʻe (e like me cellosolve, etc.), diluents, non-ionic surfactants, synthetic detergents, antifreeze, disinfectants, tougheners and plasticizers, etc. No ka mea hiki ke puhi ʻia ka ethylene oxide a loaʻa i kahi ākea pahū pahū i ka lewa, hoʻohana ʻia ia i kekahi manawa ma ke ʻano he wahie o nā pōkā pahū wahie. ʻO nā huahana hoʻopau pōʻino he carbon monoxide a me carbon dioxide. Hoʻohana ʻia ka hapa nui o ka ethylene oxide e hana i nā kemika ʻē aʻe, ka nui o ka ethylene glycol. ʻO ka Ethylene oxide he mea lapalapa a pahū, a ʻaʻole maʻalahi ka lawe ʻana ma kahi lōʻihi, no laila he mau ʻano ʻāpana ikaika.

①Hoʻomaʻemaʻe:

He hopena bactericidal ka Ethylene oxide, ʻaʻohe corrosive i nā metala, ʻaʻohe koena ʻala, a hiki ke pepehi i ka maʻi bacteria (a me kāna mau endospores), molds a me nā haʻi, no laila hiki ke hoʻohana ʻia e disinfect i kekahi mau mea a me nā mea hiki ʻole ke kū i ka disinfection wela kiʻekiʻe. .

② kumu waiwai kemika:

Hoʻohana nui ʻia ka Ethylene oxide e hana i ka ethylene glycol (mea maka no ka fiber polyester), nā mea holoi synthetic, non-ionic surfactants, antifreeze, emulsifiers, a me nā huahana ethylene glycol. Hoʻohana ʻia ia e hana i nā plasticizers, Lubricants, rubber and plastics, etc.
