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 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. 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. .
