I-Ethylene oxide (ETO)

Iiparamitha zobugcisa

I-ethylene oxide yenye yezona zilula ze-ethers ze-cyclic. Yikhompawundi ye-heterocyclic. Indlela yayo yeekhemikhali yiC2H4O. Iyi-carcinogen enetyhefu kunye nemveliso ebalulekileyo yepetrochemical. Iimpawu zeekhemikhali ze-ethylene oxide zisebenza kakhulu. Inokungena kwiimpendulo zokongezwa kweringi kunye neekhompawundi ezininzi kwaye inokunciphisa i-nitrate yesilivere. Kulula ukwenza i-polymerize emva kokufudumala kwaye inokubola phambi kweetyuwa zetsimbi okanye i-oxygen. I-ethylene oxide lulwelo olungenambala noluselubala kwiqondo lobushushu eliphantsi, kunye nerhasi engenambala enevumba elibukhali leether kubushushu obuqhelekileyo. Uxinzelelo lomphunga werhasi luphezulu, lufikelela kwi-141kPa kuma-30°C. Olu xinzelelo luphezulu lomphunga lumisela i-epoxy Amandla okungena anamandla ngexesha lokutshisa i-ethane kunye nokubulala iintsholongwane. I-Ethylene oxide inempembelelo ye-bactericidal, ayidliyo kwiintsimbi, ayinavumba elishiyekileyo, kwaye inokubulala ibhaktheriya (kunye ne-endospores yayo), i-molds kunye ne-fungi, ngoko ingasetyenziselwa ukubulala iintsholongwane kwezinye izinto kunye nezinto ezingenakukwazi ukumelana nokushisa kwe-disinfection. . . I-Ethylene oxide sisibulala-ntsholongwane seekhemikhali sesizukulwana sesibini emva kwe-formaldehyde. Isesinye sezona zibulali ntsholongwane zibandayo. Ikwazezona teknoloji zine ziphambili zobushushu obuphantsi (iplasma yobushushu obuphantsi, ubushushu obuphantsi be-formaldehyde umphunga, i-ethylene oxide). , Glutaraldehyde) elona lungu libalulekileyo. I-ethylene oxide ikwasetyenziswa kakhulu ukwenza ezinye izinyibilikisi ezahlukeneyo (ezifana ne-cellosolve, njl.), izinyibilikisi, ii-non-ionic surfactants, ii-synthetic detergents, antifreeze, disinfectants, tougheners and plasticizers, njl. Ngenxa yokuba i-ethylene oxide inokutsha kwaye inoluhlu olubanzi lweziqhushumbisi emoyeni, ngamanye amaxesha isetyenziswa njengenxalenye yamafutha kwiziqhushumbisi zegesi yegesi. Iimveliso zokutsha ezinobungozi yikharbon monoxide kunye necarbon dioxide. Uninzi lwe-ethylene oxide isetyenziselwa ukwenza ezinye iikhemikhali, ngakumbi i-ethylene glycol. I-ethylene oxide iyatsha kwaye iyaqhuma, kwaye akulula ukuyihambisa kumgama omde, ngoko ineempawu ezinamandla zengingqi.

Isicelo:

①Ukuvalwa:

I-Ethylene oxide inempembelelo ye-bactericidal, ayidliyo kwiintsimbi, ayinavumba elishiyekileyo, kwaye inokubulala ibhaktheriya (kunye ne-endospores yayo), i-molds kunye ne-fungi, ngoko ingasetyenziselwa ukubulala iintsholongwane kwezinye izinto kunye nezinto ezingenakukwazi ukumelana nokushisa kwe-disinfection. .

② imathiriyeli esisiseko yeekhemikhali:

I-ethylene oxide isetyenziselwa ukwenza i-ethylene glycol (izinto eziluhlaza kwifiber ye-polyester), i-synthetic detergents, i-non-ionic surfactants, i-antifreeze, i-emulsifiers, kunye neemveliso ze-ethylene glycol. Ikwasetyenziselwa ukuvelisa iiplastiki, iiLubricants, irabha kunye neeplastiki, njl.
