CAS No. 115-25-3 Octafluorocyclobutane Supplier. Iimpawu ze-Octafluorocyclobutane
I-Octafluorocyclobutane, eyaziwa ngokuba yi-perfluorocyclobutane okanye i-PFCB, ine-formula ye-chemical C4F8 kunye nenombolo ye-CAS 115-25-3. Le khompawundi lilungu losapho lwe-perfluorocarbon kwaye lusetyenziswa ngokuyintloko kwishishini le-semiconductor kunye negesi engasebenziyo kwizicelo ezahlukeneyo. Ngezantsi kukho iimpawu eziphambili ze-octafluorocyclobutane:
Iinkcazelo Ngeempawu:
Ukubonakala: Igesi engenambala kwiqondo lokushisa kunye noxinzelelo.
Indawo yokuBilisa: Ngokumalunga ne-−38.1 °C (−36.6 °F).
Indawo ekunyibilika kuyo: Ngokumalunga ne-−135.4 °C (−211.7 °F).
Ubuninzi: Uphezulu kunomoya, malunga ne-5.1 g/L ku-0 °C (32 °F) kunye ne-1 atm.
Ukunyibilika: Ayinyibiliki emanzini kodwa inokunyibilika kwezinye izinyibilikisi eziphilayo.
Iinkcazelo ngeMichiza:
Uzinzo: Izinzile phantsi kweemeko eziqhelekileyo kodwa inokubola xa ibekwe kumaqondo obushushu aphezulu kakhulu okanye isibane esinamandla se-UV, esinakho ukukhupha iigesi eziyityhefu nezinobungozi ezifana ne-HF (hydrogen fluoride).
Ukuphinda kusebenze: Ukungasetyenziswa ngokubanzi kwezinto ezininzi eziqhelekileyo; nangona kunjalo, inokusabela ngobundlobongela kunye nezixhobo ezinamandla ze-oxidizing.
Usebenzisa:
Ishishini leSemiconductor: Isetyenziswa njenge-etchant kunye ne-arhente yokucoca kwiinkqubo zokwenziwa kwe-semiconductor.
Usetyenziso lwezoNyango: Isetyenziswa njenge-arhente echaseneyo kubuchule bokucinga bezonyango njenge-ultrasound.
Igesi ye-Inert: Isetyenziswa njengegesi engasebenziyo kwizicelo ezahlukeneyo apho kufuneka indawo engena-oxygen.
I-Propellant: Ngamanye amaxesha isetyenziswa njenge-propellant kwi-aerosols ngenxa yokuzinza kwayo kunye nokusebenza okuphantsi.
Impembelelo yokusingqongileyo:
I-Greenhouse Gas: I-Octafluorocyclobutane yigesi enamandla ye-greenhouse kunye namandla aphezulu okufudumala kwehlabathi (GWP) kwixesha le-100 leminyaka.
I-Ozone Layer: Ayiwohlisi i-ozone layer kodwa inegalelo elikhulu kutshintsho lwemozulu ngenxa yobomi bayo obude be-atmospheric kunye ne-GWP ephezulu.
Ababoneleli:
Xa uphethe i-octafluorocyclobutane, qinisekisa ukuba unomoya ofanelekileyo, nxiba izixhobo ezifanelekileyo zokuzikhusela (PPE), kwaye unokufikelela kwiinkqubo zokusabela kwingxakeko. Soloko uyigcine kwindawo epholileyo, neyomileyo kude nezinto ezingahambelaniyo kunye nemithombo yokutshisa.
