I-Octafluorocyclobutane (C4F8)

Iiparameters zobugcisa

I-Octafluorocyclobutane sisithako sekhemikhali, into ephuma kwi-cyclobutane efakwe i-perfluorine, kwaye ifomula yayo yekhemikhali yi-C4F8. Igesi engenambala, engenavumba, engatshiyo. Izinzile ngokwendalo kwaye ayinatyhefu. Kwimeko yobushushu obuphezulu, uxinzelelo lwangaphakathi lwesikhongozeli luya kunyuka, kwaye kuya kubakho umngcipheko wokuqhekeka nokuqhuma. Imveliso yokutsha (ukubola) yi-hydrogen fluoride. I-Octafluorocyclobutane izinzile kakhulu kwaye ayisebenzi nezinye izinto phantsi kweemeko eziqhelekileyo. Isitya sokugcina kunye nesokusabela singenziwa ngentsimbi ephosiweyo kunye nentsimbi engatyiwayo kwi-120°C, kwaye intsimbi ingasetyenziswa kwi-175°C. Xa idlula kwi-400°C, Izinto ze-Inconel ezifana ne-nickel kunye neplatinum nazo zinokonakala kancinci. Kwi-500°C, ezi zinto zinefuthe lokutsala ekuboleni. Kwiqondo lobushushu eliphezulu (600°C), i-octafluorocyclobutane inokubola ibe yi-carbon, i-carbon tetrafluoride kunye neekhompawundi ezinobuthi. I-Octafluorocyclobutane inoluhlu olubanzi kakhulu lwezicelo. Kwiminyaka yakutshanje, isetyenziswa kakhulu njengefriji ukuze ithathe indawo yeekhompawundi ze-chlorofluorocarbon ezingavumelekanga. Ukongeza, ikwasetyenziswa kakhulu kwimidiya yokukhusela igesi, izinyibilikisi, izitshizi, ii-agents ezikhupha amagwebu, kunye nee-etchants ezinkulu zesekethe. , Ulwelo olusebenzayo lwepompo yobushushu kunye nezinto eziluhlaza zokuvelisa ii-monomers ze-C2F4 kunye ne-C3F6. I-octafluorocyclobutane ecocekileyo kakhulu (ngaphezulu kwe-5N) isetyenziswa njengearhente yokutshiza kunye nearhente yokucoca kwiisekethe ze-VLSI. Ngenxa yeempawu zayo ezizinzileyo, ukungabi natyhefu, amandla okuphela kwe-ozone (ODP) engekhoyo, kunye nokufakelwa okuhle, i-octafluorocyclobutane isetyenziswa kakhulu kwiinkalo zobugcisa ezifana nokufakelwa kwe-voltage ephezulu, ukucoca kunye nokufakelwa, kunye nonyango lwe-plasma kwiminyaka yakutshanje. Impendulo engxamisekileyo yokuvuza: nxiba izixhobo zokuphefumla ezizimeleyo kunye neempahla zokusebenza. Sika umthombo wegesi. Umoya kunye nokufakwa komoya, ukunyibilikisa kunye nokusasazwa. Hambisa isikhongozeli esivuzayo kwindawo evulekileyo kwaye uqaphele umoya. Izikhongozeli ezivuzayo azisenakusetyenziswa, kwaye kufuneka ziphathwe ngobuchwephesha ukuze kususwe igesi eseleyo.

Isicelo:

① Ishishini Lokutya:

Isetyenziswa kakhulu njengearhente yokutshiza kwishishini lokutya, njengefriji.

② Ishishini le-elektroniki:

Inomtsalane kwisekethe edibeneyo, ikwasetyenziswa njengomxube we-dielectric kunye ne-sf6, kunye noncedo lwe-polymerization kwi-fluorinated compound.

Iphakheji eqhelekileyo:
