Ethylene Oxide (ETO)

Fa'agata fa'atekinisi

O le Ethylene oxide o se tasi o ethers sili ona faigofie. O se fa'apotopotoga heterocyclic. O lona fua fa'atatau ole C2H4O. Ose fa'ama'i oona ma ose mea tau petrochemical. O mea tau vaila'au o le ethylene oxide e matua malosi lava. E mafai ona o'o i tali fa'aopoopo e tatala mama ma le tele o mea fa'afefiloi ma e mafai ona fa'aitiitia le nita siliva. E faigofie ona polymerize pe a uma ona vevela ma e mafai ona pala i le i ai o masima uʻamea poʻo le okesene. O le Ethylene oxide o se vai e leai ni lanu ma manino i le vevela maualalo, ma o se kasa e leai ni lanu ma le manogi manogi eter i le vevela masani. O le mamafa o le ausa o le kesi e maualuga, e oʻo atu i le 141kPa ile 30°C. O le maualuga o le ausa o le mamafa e fuafua ai le epoxy Malosi o le malosi i le taimi o le ethane fumigation ma faʻamaʻi. O le Ethylene oxide e iai sona aafiaga fa'ama'i, e le fa'aleagaina i u'amea, e leai se manogi o totoe, ma e mafai ona fasiotia siama (ma ona endospores), molds ma ga'o, o lea e mafai ai ona fa'aoga e fa'amama ai nisi o mea ma mea e le mafai ona tatalia le vevela maualuga . . Ethylene oxide o le fa'ama'i fa'ama'i fa'ama'i fa'atupu-fa'alua lona lua pe a uma formaldehyde. O lo'o avea pea ma se tasi o vaila'au malulu sili ona lelei. E fa'apea fo'i ma fa'atekonolosi fa'amama fa'ama'a'a maualalo (plasma maualalo, ausa formaldehyde maualalo, ethylene oxide). , Glutaraldehyde) o le sui sili ona taua. O le Ethylene oxide e masani ona faʻaaogaina e fai ai isi solvents (e pei o le cellosolve, ma isi), faʻafefeteina, mea e le ionic surfactants, vailaʻau faʻapipiʻi, antifreeze, disinfectants, tougheners ma plasticizers, ma isi. Talu ai ona o le ethylene oxide e mu ma e iai le lautele o mea pāpā i luga ole ea, o nisi taimi e faʻaaogaina e avea ma vaega fafie o pomu faʻafefe. O mea fa'amumu fa'aleagaina o le kaponi monoxide ma le carbon dioxide. Ole tele ole ethylene oxide e fa'aaogaina e fai ai isi vaila'au, aemaise ole ethylene glycol. O le Ethylene oxide e mu ma pa, ma e le faigofie ona felauaiga i luga o mamao mamao, o lea e malosi ai uiga faʻaitulagi.

② meafaitino mata'ina kemikolo:

O le ethylene oxide e masani lava ona faʻaaogaina e fai ai le ethylene glycol (mea mataʻutia mo alava polyester), vailaʻau faʻapipiʻi, mea e leai ni ionic surfactants, antifreeze, emulsifiers, ma oloa ethylene glycol. E faʻaaogaina foi e gaosia ai mea faʻapipiʻi, Lubricants, paʻu ma palasitika, ma isi.
