Izingxube ze-Ethylene oxide & Carbon Dioxide

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 iwubuchwepheshe 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.Ngokuvamile sebenzisa i-ethylene oxide-carbon dioxide (isilinganiso salokhu okubili ngu-90:10) noma ingxube ye-ethylene oxide-dichlorodifluoromethane, ikakhulukazi esetshenziselwa ukubulala amagciwane ezibhedlela namathuluzi anembayo.I-ethylene oxide iyavutha futhi iyaqhuma, futhi izakhiwo zayo zamakhemikhali zisebenza kakhulu.Ingabhekana nokungezwa kokuvula indandatho ngezinhlanganisela eziningi.Akulula ukuthutha ngokuhamba amabanga amade, ngakho-ke inezici zesifunda ezinamandla.Imithetho yesitoreji: Gcina endaweni epholile, nengena umoya.Gcina kude nomlilo nemithombo yokushisa.Gwema ukukhanya.Izinga lokushisa lokugcina akufanele lidlule ku-30°C.Kufanele igcinwe ngokuhlukana nama-acids, alkalis, alcohols, namakhemikhali adliwayo, futhi igweme ukugcinwa okuxubile.Sebenzisa izibani ezingaqhumi kanye nezindawo zokungenisa umoya.Akuvunyelwe ukusebenzisa imishini namathuluzi ajwayele ukuvela izinhlansi.Indawo yokugcina kufanele ifakwe okokusebenza okuphuthumayo okuvuzayo.

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. .
