Ethylene Oxide (ETO)

Litekanyetso tsa tekheniki

Ethylene oxide ke e 'ngoe ea li-ether tse bonolo ka ho fetisisa tse potolohang. Ke motsoako oa heterocyclic. Foromo ea eona ea lik'hemik'hale ke C2H4O. Ke kankere e chefo le sehlahisoa sa bohlokoa sa petrochemical. Litšobotsi tsa lik'hemik'hale tsa ethylene oxide li sebetsa haholo. E ka feta liketsong tsa ho eketsa lesale ka metsoako e mengata 'me e ka fokotsa nitrate ea silevera. Ho bonolo ho e etsa polymerize ka mor'a ho futhumatsoa 'me e ka bola ha ho e-na le letsoai la tšepe kapa oksijene. Ethylene oxide ke mokelikeli o se nang 'mala le o bonaletsang mochesong o tlase, 'me ke khase e se nang 'mala e nang le monko o bohale oa ether mochesong o tloaelehileng. Khatello ea mouoane oa khase e phahame, e fihlang ho 141kPa ho 30°C. Khatello ena e phahameng ea mouoane e khetholla epoxy Matla a matla a kenellang nakong ea ho tsubella le ho bolaea likokoana-hloko ka ethane. Ethylene oxide e na le phello ea baktheria, ha e senye 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 lintho tse ling le thepa e ke keng ea mamella ho bolaoa likokoana-hloko mochesong o phahameng. Ethylene oxide ke sebolaya-dikokwana-hloko sa dikhemikhale sa moloko wa bobedi kamora formaldehyde. E ntse e le e 'ngoe ea libolaya-dikokwana-hloko tse ntle ka ho fetisisa tse batang. Hape ke theknoloji e mene e meholo ea ho bolaea dikokwana-hloko mochesong o tlase (plasma ea mocheso o tlase, mouoane oa formaldehyde mochesong o tlase, ethylene oxide). , Glutaraldehyde) setho sa bohlokoa ka ho fetisisa. Ethylene oxide e boetse e sebelisoa haholo ho etsa li-solvent tse ling tse fapaneng (joalo ka cellosolve, jj.), diluents, non-ionic surfactants, disepa tsa maiketsetso, antifreeze, disepa tsa dikokwana-hloko, li-tougheners le li-plasticizers, jj. Hobane ethylene oxide e ka cha 'me e na le sebaka se seholo sa mahloriso a phatlohang moeeng, ka linako tse ling e sebelisoa e le karolo ea mafura ea libomo tse phatlohang tsa khase ea mafura. Lihlahisoa tse kotsi tsa ho cha ke carbon monoxide le carbon dioxide. Bongata ba ethylene oxide bo sebelisetsoa ho etsa lik'hemik'hale tse ling, haholo-holo ethylene glycol. Ethylene oxide e ka cha 'me ea phatloha, 'me ha ho bonolo ho e tsamaisa libakeng tse telele, kahoo e na le litšobotsi tse matla tsa libaka.

Kopo:

①Ho bolaea likokoana-hloko:

Ethylene oxide e na le phello ea ho bolaea libaktheria, ha e senye 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 lintho tse ling le thepa e ke keng ea mamella ho bolaea libaktheria mochesong o phahameng.

② thepa ea motheo ea lik'hemik'hale tse tala:

Ethylene oxide e sebediswa haholoholo ho etsa ethylene glycol (thepa e tala bakeng sa faeba ya polyester), disepa tsa maiketsetso, di-surfactant tse seng tsa ionic, di-antifreeze, di-emulsifier, le dihlahiswa tsa ethylene glycol. E boetse e sebediswa ho hlahisa di-plasticizer, Ditlolo, rabara le dipolasetiki, jj.
