I-CAS No. 115-25-3 Umhlinzeki we-Octafluorocyclobutane. Izici ze-Octafluorocyclobutane
I-Octafluorocyclobutane, eyaziwa nangokuthi i-perfluorocyclobutane noma i-PFCB, inefomula yamakhemikhali i-C4F8 kanye nenombolo ye-CAS 115-25-3. Le nhlanganisela iyilungu lomndeni we-perfluorocarbon futhi isetshenziswa ngokuyinhloko embonini ye-semiconductor nanjengegesi engasebenzi ekusetshenzisweni okuhlukahlukene. Ngezansi ezinye izici ezibalulekile ze-octafluorocyclobutane:
Izakhiwo Zomzimba:
Ukubukeka: Igesi engenambala ekamelweni lokushisa nokucindezela.
Indawo yokubilisa: Cishe ku-−38.1 °C (−36.6 °F).
Indawo Encibilika: Cishe ku-−135.4 °C (−211.7 °F).
Ukuminyana: Kuphakeme kunomoya, cishe ku-5.1 g/L ku-0 °C (32 °F) no-1 atm.
Ukunyibilika: Ayincibiliki emanzini kodwa ingancibilika kwezinye izinyibilikisi zemvelo.
Izakhiwo Zekhemikhali:
Ukuzinza: Izinzile ngaphansi kwezimo ezijwayelekile kodwa ingabola lapho ibhekene namazinga okushisa aphakeme kakhulu noma ukukhanya okunamandla kwe-UV, okungenzeka ikhiphe amagesi anobuthi nawokudla njenge-HF (hydrogen fluoride).
Ukusebenza kabusha: Ngokuvamile akusebenzi ngezinto ezivame kakhulu; nokho, ingasabela ngobudlova ngama-oxidizing agents aqinile.
Isebenzisa:
Imboni ye-Semiconductor: Isetshenziswa njenge-etchant kanye ne-ejenti yokuhlanza ezinqubweni zokukhiqiza ze-semiconductor.
Izicelo Zezokwelapha: Isetshenziswa njenge-ejenti yokuqhathanisa kumasu wokuthwebula wezokwelapha njenge-ultrasound.
I-Inert Gas: Isetshenziswa njengegesi engasebenzi ezindaweni ezihlukahlukene lapho kudingeka khona indawo engenawo umoya-mpilo.
I-Propellant: Kwesinye isikhathi isetshenziswa njenge-propellant kuma-aerosol ngenxa yokusimama kwayo nokusebenza kabusha okuphansi.
Umthelela Wemvelo:
I-Greenhouse Gas: I-Octafluorocyclobutane igesi ebamba ukushisa enamandla enamandla amakhulu okufudumala kwembulunga yonke (GWP) esikhathini esiyiminyaka eyi-100.
Ungqimba Lwe-ozone: Aluqedi ungqimba lwe-ozone kodwa lunomthelela omkhulu ekushintsheni kwesimo sezulu ngenxa yokuphila kwayo okude komkhathi kanye ne-GWP ephezulu.
Abahlinzeki:
Lapho uphatha i-octafluorocyclobutane, qiniseka ukuthi unomoya ofanele, gqoka izinto zokuzivikela ezifanele (i-PPE), futhi ukwazi ukufinyelela ezinqubweni zokusabela ezimweni eziphuthumayo. Ngaso sonke isikhathi igcine endaweni epholile, neyomile ekude nezinto ezingahambelani nemithombo yokubasa.
