Litšobotsi tsa ethylene oxide

Ethylene oxideke moloko oa bobeli oa li-disinfectant tsa lik'hemik'hale ka mor'a formaldehyde. E ntse e le e 'ngoe ea li-disinfectant tse ntle ka ho fetisisa tse batang le setho sa bohlokoa ka ho fetisisa mahlaleng a mane a maholo a ho bolaea likokoana-hloko mochesong o tlase.

Ethylene oxide ke motsoako o bonolo oa epoxy. Ke khase e se nang 'mala mochesong oa kamore le khatellong. E boima ho feta moea 'me e na le monko o monate oa ether. Ethylene oxide e ka tuka ebile ea phatloha.

Molao-motheo oa ho Senya Ethylene Oxide

1. Alkylation

Mokhoa oa ketso eaethylene oxideHo bolaoeng ha dikokwana-hloko tse fapaneng haholo-holo ke alkylation. Libaka tsa ketso ke sulfhydryl (-SH), amino (-NH2), hydroxyl (-COOH) le hydroxyl (-OH) limolek'huleng tsa protheine le nucleic acid. Ethylene oxide e ka etsa hore lihlopha tsena li etsahale liketsong tsa alkylation, e leng se etsang hore limolek'hule tsena tsa baeloji tsa dikokwana-hloko li se ke tsa sebetsa, ka hona li bolaoe ke dikokwana-hloko.

2. Thibela mosebetsi oa li-enzyme tsa baeloji

Ethylene oxide e ka thibela ts'ebetso ea li-enzyme tse fapaneng tsa likokoana-hloko, tse kang phosphate dehydrogenase, cholinesterase le li-oxidase tse ling, e sitisa ho phethoa ha lits'ebetso tse tloaelehileng tsa metabolism ea likokoana-hloko 'me e lebisa lefung la tsona.

Ethylene oxide ke sebolaya-mafu se sebetsang hantle haholo se nang le phello e matla ea ho bolaea le ho emisa ho ata ha libaktheria, li-spores tsa baktheria, li-fungus le livaerase. Ha ethylene oxide e kopana le likokoana-hloko, empa likokoana-hloko li na le metsi a lekaneng, karabelo pakeng tsa ethylene oxide le likokoana-hloko ke karabelo e tloaelehileng ea tatellano ea pele.
