CAS No. 115-25-3 Octafluorocyclobutane Wopereka. Makhalidwe a Octafluorocyclobutane
Octafluorocyclobutane, yomwe imadziwikanso kuti perfluorocyclobutane kapena PFCB, ili ndi mankhwala a C4F8 ndi nambala ya CAS 115-25-3. Pagululi ndi membala wa banja la perfluorocarbon ndipo amagwiritsidwa ntchito makamaka m'makampani opanga ma semiconductor komanso ngati mpweya wolowera m'njira zosiyanasiyana. M'munsimu muli zizindikiro zazikulu za octafluorocyclobutane:
Katundu Wathupi:
Maonekedwe: Gasi wopanda mtundu pa kutentha ndi kupanikizika.
Malo Owira: Mozungulira −38.1 °C (−36.6 °F).
Malo Osungunuka: Mozungulira −135.4 °C (−211.7 °F).
Kachulukidwe: Kukwera kuposa mpweya, pafupifupi 5.1 g/L pa 0 °C (32 °F) ndi 1 atm.
Kusungunuka: Kusasungunuka m'madzi koma kumatha kusungunuka muzosungunulira zina.
Chemical Properties:
Kukhazikika: Kukhazikika m'malo abwinobwino koma kumatha kuwola kukakhala kutentha kwambiri kapena kuwala kwamphamvu kwa UV, komwe kumatha kutulutsa mpweya wapoizoni ndi dzimbiri monga HF (hydrogen fluoride).
Reactivity: Nthawi zambiri osachitapo kanthu ndi zinthu zodziwika bwino; komabe, imatha kuchita mwankhanza ndi ma oxidizing amphamvu.
Zogwiritsa:
Makampani a Semiconductor: Amagwiritsidwa ntchito ngati etchant ndi kuyeretsa popanga semiconductor.
Kugwiritsa Ntchito Zachipatala: Amagwiritsidwa ntchito ngati chosiyanitsa munjira zamaganizidwe azachipatala monga ultrasound.
Gasi Wopanda mpweya: Amagwiritsidwa ntchito ngati mpweya wolowera m'malo osiyanasiyana pomwe malo opanda mpweya amafunikira.
Propellant: Nthawi zina amagwiritsidwa ntchito ngati chothandizira mu ma aerosol chifukwa cha kukhazikika kwake komanso kutsika kwake.
Zachilengedwe:
Gasi Wowonjezera Kutentha: Octafluorocyclobutane ndi mpweya wowonjezera kutentha womwe uli ndi mphamvu yayikulu ya kutentha kwapadziko lonse (GWP) pazaka 100.
Ozone Layer: Simawononga mpweya wa ozoni koma umathandizira kwambiri kusintha kwa nyengo chifukwa cha moyo wake wautali wamlengalenga komanso kuchuluka kwa GWP.
Othandizira:
Pamene mukugwira octafluorocyclobutane, onetsetsani kuti muli ndi mpweya wabwino, valani zipangizo zodzitetezera (PPE), ndipo mutha kupeza njira zothandizira mwadzidzidzi. Nthawi zonse sungani pamalo ozizira, owuma kutali ndi zinthu zosagwirizana ndi komwe mungayatseko.
