Ethylene oxide (ETO)

Litekanyetso tsa tekheniki

Ethylene oxide ke e 'ngoe ea li-ether tse bonolo ka ho fetisisa tsa cyclic. Ke motsoako oa heterocyclic. Foromo ea eona ea lik'hemik'hale ke C2H4O. Ke carcinogen e chefo le sehlahisoa sa bohlokoa sa petrochemical. Lik'hemik'hale tsa ethylene oxide li sebetsa haholo. E ka kena ka har'a liketso tsa ho eketsa li-ring-opening ka metsoako e mengata 'me e ka fokotsa silevera ea nitrate. Ho bonolo ho etsa polymeri ka mor'a ho futhumala 'me e ka bola ka pel'a matsoai a tšepe kapa oksijene. Ethylene oxide ke mokelikeli o se nang mebala le o bonaletsang mochesong o tlase, le khase e se nang 'mala e monko o monate oa ether mochesong o tloaelehileng. Khatello ea mouoane oa khase e phahame, e fihla ho 141kPa ho 30°C. Khatello ena e phahameng ea mouoane e etsa qeto ea matla a matla a epoxy a matla a phunyeletsang nakong ea mouoane oa ethane le ho bolaea likokoana-hloko. Ethylene oxide e na le phello ea bactericidal, ha e senya litšepe, ha e na monko o setseng, 'me e ka bolaea libaktheria (le li-endospores tsa eona), hlobo le li-fungus, kahoo e ka sebelisoa ho bolaea likokoana-hloko tse ling le lisebelisoa tse ke keng tsa mamella mocheso o phahameng oa ho bolaea likokoana-hloko. . . Ethylene oxide ke sebolaea likokoana-hloko sa moloko oa bobeli ka mor'a formaldehyde. E ntse e le e 'ngoe ea li-disinfectants tse ntle ka ho fetisisa tse batang. Hape ke litheknoloji tse 'ne tse kholo tsa ho thibela mocheso o tlase (plasma ea mocheso o tlase, mocheso o tlase oa formaldehyde mouoane, ethylene oxide). , Glutaraldehyde) setho sa bohlokoa ka ho fetisisa. Ethylene oxide e boetse e sebelisoa haholo ho etsa metsoako e meng e fapaneng (joalo ka cellosolve, joalo-joalo), diluents, non-ionic surfactants, synthetic detergents, antifreeze, disinfectants, tougheners le plasticizers, joalo-joalo. Hobane ethylene oxide e ka cha 'me e na le mefuta e mengata e phatlohileng moeeng, ka linako tse ling e sebelisoa e le karolo ea mafura a libomo tse phatlohang tsa gasification. Lihlahisoa tse kotsi tsa ho tuka ke carbon monoxide le carbon dioxide. Boholo ba ethylene oxide e sebelisoa ho etsa lik'hemik'hale tse ling, haholo-holo ethylene glycol. Ethylene oxide e chesa ebile ea phatloha, 'me ha ho bonolo ho e tsamaisa libakeng tse telele, kahoo e na le litšobotsi tse matla tsa libaka.

Kopo:

①Ho sterilization:

Ethylene oxide e na le phello ea bactericidal, ha e senya litšepe, ha e na monko o setseng, 'me e ka bolaea libaktheria (le li-endospores tsa eona), hlobo le li-fungus, kahoo e ka sebelisoa ho bolaea likokoana-hloko tse ling le lisebelisoa tse ke keng tsa mamella mocheso o phahameng oa ho bolaea likokoana-hloko. .

② lisebelisoa tsa mantlha tsa lik'hemik'hale:

Ethylene oxide e sebelisoa haholo ho etsa ethylene glycol (lisebelisoa tse tala bakeng sa fiber ea polyester), li-detergents, li-non-ionic surfactants, antifreeze, emulsifiers, le lihlahisoa tsa ethylene glycol. E boetse e sebelisetsoa ho hlahisa li-plasticizers, Lubricants, rabara le polasetiki, joalo-joalo.
