CAS No. 115-25-3 Octafluorocyclobutane Supplier. Cov yam ntxwv ntawm Octafluorocyclobutane

Octafluorocyclobutane, tseem hu ua perfluorocyclobutane los yog PFCB, muaj cov tshuaj formula C4F8 thiab CAS naj npawb 115-25-3. Cov compound no yog ib tug tswv cuab ntawm tsev neeg perfluorocarbon thiab feem ntau yog siv nyob rau hauv lub semiconductor kev lag luam thiab raws li ib tug inert roj nyob rau hauv ntau yam kev siv. Hauv qab no yog qee cov yam ntxwv tseem ceeb ntawm octafluorocyclobutane:

Lub cev muaj zog:
Cov tsos mob: tsis muaj xim tsis muaj roj ntawm chav tsev kub thiab siab.
Boiling Point: Nyob ib ncig ntawm -38.1 ° C (−36.6 ° F).
Melting Point: Nyob ib ncig ntawm -135.4 ° C (-211.7 ° F).
Qhov ceev: siab tshaj huab cua, kwv yees li 5.1 g / L ntawm 0 ° C (32 ° F) thiab 1 atm.
Solubility: Insoluble hauv dej tab sis tuaj yeem yaj hauv qee cov kuab tshuaj organic.
Chemical Properties:
Kev ruaj ntseg: ruaj khov nyob rau hauv ib txwm muaj tab sis tuaj yeem decompose thaum raug kub heev lossis muaj zog UV lub teeb, muaj peev xwm tso tawm cov pa phem thiab corrosive xws li HF (hydrogen fluoride).
Reactivity: Feem ntau unreactive nrog feem ntau cov tshuaj; Txawm li cas los xij, nws tuaj yeem hnov ​​​​mob hnyav nrog cov tshuaj oxidizing muaj zog.
Kev siv:
Kev lag luam semiconductor: Siv los ua etchant thiab tu tus neeg sawv cev hauv cov txheej txheem tsim khoom semiconductor.
Kev Siv Kho Mob: Siv los ua tus neeg sawv cev sib txawv hauv kev kho mob cov tswv yim zoo li ultrasound.
Inert Gas: Siv cov roj inert hauv ntau daim ntawv thov uas yuav tsum muaj qhov chaw tsis muaj oxygen.
Propellant: Qee lub sij hawm siv los ua tus kiv cua hauv aerosols vim nws qhov ruaj khov thiab tsis tshua muaj zog.
Environmental Impact:
Greenhouse Gas: Octafluorocyclobutane yog lub tsev cog khoom muaj zog nrog lub ntiaj teb ua kom sov siab (GWP) dhau 100 xyoo.
Ozone Layer: Nws tsis deplete lub ozone txheej tab sis muaj txiaj ntsig zoo rau kev hloov pauv huab cua vim nws lub neej ntev atmospheric thiab siab GWP.
Cov neeg muab khoom:
Thaum tuav octafluorocyclobutane, xyuas kom meej tias koj muaj qhov cua kom raug, hnav cov khoom tiv thaiv tus kheej tsim nyog (PPE), thiab muaj kev nkag mus rau cov txheej txheem teb thaum muaj xwm txheej ceev. Nco ntsoov khaws cia rau hauv qhov chaw txias, qhuav kom deb ntawm cov khoom siv tsis sib xws thiab cov khoom siv hluav taws xob.
