I-Ethylene oxide (ETO)

Imingcele yezobuchwepheshe

I-Ethylene oxide ingenye ye-ethers elula yama-cyclic. Kuyinhlanganisela ye-heterocyclic. Ifomula yayo yamakhemikhali ithi C2H4O. Kuyi-carcinogen enobuthi kanye nomkhiqizo obalulekile we-petrochemical. Amakhemikhali e-ethylene oxide asebenza kakhulu. Ingabhekana nokungezwa kokuvula indandatho ngezinhlanganisela eziningi futhi inganciphisa i-nitrate esiliva. Kulula ukwenza i-polymerize ngemva kokushisisa futhi ingabola lapho kukhona usawoti wensimbi noma umoya-mpilo. I-Ethylene oxide iwuketshezi olungenambala futhi olusobala ezingeni lokushisa eliphansi, kanye negesi engenambala enephunga elimnandi le-ether ezingeni lokushisa elivamile. Umfutho womhwamuko wegesi uphezulu, ufinyelela ku-141kPa ku-30°C. Lokhu kucindezela komhwamuko omkhulu kunquma amandla angena e-epoxy Anamandla ngesikhathi sokufuthwa kwe-ethane nokubulala amagciwane. I-Ethylene oxide inomphumela we-bactericidal, ayigqwali ezinsimbi, ayinayo iphunga elisele, futhi ingabulala amagciwane (kanye nama-endospores ayo), isikhunta kanye nesikhunta, ngakho-ke ingasetshenziswa ukubulala amagciwane ezinye izinto nezinto ezingakwazi ukumelana nokushisa okuphezulu kokubulala amagciwane. . . I-Ethylene oxide iyisibulala-magciwane samakhemikhali esizukulwane sesibili ngemva kwe-formaldehyde. Kusengenye yezibulala-magciwane ezibandayo ezingcono kakhulu. Futhi kuwubuchwepheshe obune obukhulu bokuvala inzalo yezinga lokushisa eliphansi (i-plasma enezinga lokushisa eliphansi, izinga lokushisa eliphansi le-formaldehyde steam, i-ethylene oxide). , Glutaraldehyde) ilungu elibaluleke kakhulu. I-Ethylene oxide ibuye isetshenziswe kakhulu ukwenza ezinye izinyibilikisi ezinhlobonhlobo (njenge-cellosolve, njll.), izincibilikisi, ama-non-ionic surfactants, iziwashi zokwenziwa, i-antifreeze, izibulala-magciwane, ama-tougheners namapulasitiki, njll. Ngenxa yokuthi i-ethylene oxide iyakwazi ukuvutha futhi inobubanzi obubanzi beziqhumane emoyeni, ngezinye izikhathi isetshenziswa njengengxenye kaphethiloli yamabhomu aqhumayo afaka isisi. Imikhiqizo evuthayo eyingozi yi-carbon monoxide ne-carbon dioxide. Iningi le-ethylene oxide lisetshenziselwa ukwenza amanye amakhemikhali, ikakhulukazi i-ethylene glycol. I-ethylene oxide iyavutha futhi iyaqhuma, futhi akulula ukuyihambisa amabanga amade, ngakho inezici zesifunda ezinamandla.

Isicelo:

①Ukuvalwa inzalo:

I-Ethylene oxide inomphumela we-bactericidal, ayigqwali ezinsimbi, ayinayo iphunga elisele, futhi ingabulala amagciwane (kanye nama-endospores ayo), isikhunta kanye nesikhunta, ngakho-ke ingasetshenziswa ukubulala amagciwane ezinye izinto nezinto ezingakwazi ukumelana nokushisa okuphezulu kokubulala amagciwane. .

② izinto eziyisisekelo zamakhemikhali:

I-ethylene oxide isetshenziswa kakhulu ukwenza i-ethylene glycol (impahla eluhlaza ye-polyester fibre), okokuhlanza okokwenziwa, izinto ezikhipha ama-non-ionic, ama-antifreeze, ama-emulsifiers, kanye nemikhiqizo ye-ethylene glycol. Iphinde isetshenziselwe ukukhiqiza plasticizers, Lubricant, iraba kanye plastics, njll.
