Ethylene Oxide (ETO)

Technical parameters

Ethylene oxide ndeimwe yeakareruka cyclic ether. Iyo inhengo yeheterocyclic. Yayo kemikari formula ndeye C2H4O. Iyo ine muchetura carcinogen uye yakakosha petrochemical chigadzirwa. Iyo makemikari ethylene oxide anoshanda zvakanyanya. Inogona kuita ring-kuvhura yekuwedzera maitiro nemakomponi akawanda uye inogona kuderedza sirivheri nitrate. Zviri nyore kuita polymerize mushure mekupisa uye inogona kuora pamberi pesimbi yemunyu kana oxygen. Ethylene oxide imvura isina ruvara uye inoonekera pane tembiricha yakaderera, uye gasi risina ruvara rine ether pungent hwema pakupisa kwakajairika. Hutsi hwehutsi hwegasi hwakakwira, hunosvika 141kPa pa30°C. Iyi yakakwira mhute pressure inosarudza epoxy Yakasimba inopinda simba panguva ye ethane fumigation uye disinfection. Ethylene oxide ine bactericidal effect, haiparadzi simbi, haina kunhuhwirira kwasara, uye inogona kuuraya mabhakitiriya (uye endospores ayo), molds uye fungi, saka inogona kushandiswa kuuraya utachiona zvimwe zvinhu uye zvinhu zvisingakwanise kutsungirira kupisa kwakanyanya. . . Ethylene oxide ndiyo yechipiri-chizvarwa chemakemikari disinfectant mushure me formaldehyde. Ichiri imwe yeakanakisa inotonhora disinfectants. Ndiwo zvakare mana makuru ekudzika-tembiricha tekinoroji (yakaderera-tembiricha plasma, yakaderera-tembiricha formaldehyde steam, ethylene oxide). , Glutaraldehyde) nhengo inonyanya kukosha. Ethylene oxide inonyanya kushandiswa kugadzira zvimwe zvakasiyana-siyana zvinonyungudutsa (sesellosolve, nezvimwewo), diluents, non-ionic surfactants, synthetic detergents, antifreeze, disinfectants, tougheners uye plasticizers, nezvimwewo. Nekuti ethylene oxide inopfuta uye ine kuputika kwakakura kwehuwandu mumhepo, dzimwe nguva inoshandiswa sechikamu chemafuta emafuta gasification anoputika mabhomba. Izvo zvinokuvadza zvinopisa zvigadzirwa zvinopisa kabhoni monoxide uye carbon dioxide. Yakawanda ye ethylene oxide inoshandiswa kugadzira mamwe makemikari, kunyanya ethylene glycol. Ethylene oxide inopfuta uye inoputika, uye haisi nyore kutakura nekufamba madaro marefu, saka ine hunhu hwakasimba hwedunhu.

Application:

① Sterilization:

Ethylene oxide ine bactericidal effect, haiparadzi simbi, haina kunhuhwirira kwasara, uye inogona kuuraya mabhakitiriya (uye endospores ayo), molds uye fungi, saka inogona kushandiswa kuuraya utachiona zvimwe zvinhu uye zvinhu zvisingakwanise kutsungirira kupisa kwakanyanya. .

② yakakosha kemikari mbishi zvinhu:

Ethylene oxide inonyanya kushandiswa kugadzira ethylene glycol (raw material for polyester fiber), synthetic detergents, non-ionic surfactants, antifreeze, emulsifiers, uye ethylene glycol zvigadzirwa. Inoshandiswawo kugadzira plasticizers, Lubricant, rabha uye mapurasitiki, nezvimwe.
