Ethylene Oxide (ETO)

Technical parameters

Ethylene oxide yog ib qho yooj yim cyclic ethers. Nws yog heterocyclic compound. Nws cov tshuaj formula yog C2H4O. Nws yog ib qho tshuaj lom carcinogen thiab ib qho tseem ceeb petrochemical khoom. Cov khoom siv tshuaj lom neeg ntawm ethylene oxide muaj zog heev. Nws tuaj yeem raug lub nplhaib-qhib ntxiv cov tshuaj tiv thaiv nrog ntau lub tebchaw thiab tuaj yeem txo cov nyiaj nitrate. Nws yog ib qho yooj yim rau polymerize tom qab rhuab thiab decompose nyob rau hauv lub xub ntiag ntawm hlau ntsev los yog oxygen. Ethylene oxide yog cov kua tsis muaj xim thiab pob tshab ntawm qhov kub thiab txias, thiab cov roj tsis muaj xim nrog ether pungent tsw ntawm qhov kub thiab txias. Lub vapor siab ntawm cov pa roj yog siab, ncav cuag 141kPa ntawm 30 ° C. Qhov siab vapor siab no txiav txim siab txog epoxy Strong penetrating zog thaum ethane fumigation thiab tshuaj tua kab mob. Ethylene oxide muaj cov kab mob bactericidal, tsis corrosive rau hlau, tsis muaj ntxhiab tsw seem, thiab tuaj yeem tua cov kab mob (thiab nws cov endospores), pwm thiab fungi, yog li nws tuaj yeem siv los tua kab mob qee yam khoom thiab cov ntaub ntawv uas tsis tuaj yeem tiv taus cov tshuaj tua kab mob siab. . . Ethylene oxide yog cov tshuaj tua kab mob thib ob tom qab formaldehyde. Nws tseem yog ib qho ntawm cov tshuaj tua kab mob zoo tshaj plaws. Nws tseem yog plaub qhov tseem ceeb ntawm kev ua kom tsis muaj qhov kub thiab txias technologies (low-temperature plasma, low-temperature formaldehyde steam, ethylene oxide). , Glutaraldehyde) cov tswv cuab tseem ceeb tshaj plaws. Ethylene oxide kuj tseem siv los ua ntau yam kuab tshuaj (xws li cellosolve, thiab lwm yam), diluents, non-ionic surfactants, hluavtaws detergents, antifreeze, tshuaj tua kab mob, tougheners thiab plasticizers, thiab lwm yam. Vim hais tias ethylene oxide yog nplaim taws thiab muaj ntau qhov sib txawv ntawm cov huab cua, qee zaum nws yog siv los ua cov roj ntawm cov roj gasification tawg tawg. Cov khoom tsim kev puas tsuaj yog carbon monoxide thiab carbon dioxide. Feem ntau ntawm ethylene oxide yog siv los ua lwm yam tshuaj, feem ntau yog ethylene glycol. Ethylene oxide yog nplaim taws thiab tawg, thiab nws tsis yooj yim rau kev thauj mus los ntev, yog li nws muaj zog hauv cheeb tsam.

Daim ntawv thov:

① Sterilization:

Ethylene oxide muaj cov kab mob bactericidal, tsis corrosive rau hlau, tsis muaj ntxhiab tsw seem, thiab tuaj yeem tua cov kab mob (thiab nws cov endospores), pwm thiab fungi, yog li nws tuaj yeem siv los tua kab mob qee yam khoom thiab cov ntaub ntawv uas tsis tuaj yeem tiv taus cov tshuaj tua kab mob siab. .

② Cov khoom siv tshuaj lom neeg yooj yim:

Ethylene oxide feem ntau yog siv los ua ethylene glycol (raw khoom rau polyester fiber), hluavtaws detergents, non-ionic surfactants, antifreeze, emulsifiers, thiab ethylene glycol khoom. Nws kuj yog siv los tsim cov yas yas, Lubricants, roj hmab thiab yas, thiab lwm yam.
