CAS No. 115-25-3 Alaabta Octafluorocyclobutane. Astaamaha Octafluorocyclobutane
Octafluorocyclobutane, oo sidoo kale loo yaqaan perfluorocyclobutane ama PFCB, ayaa leh qaacidada kiimikada C4F8 iyo lambarka CAS 115-25-3. Xaruntani waa xubin ka mid ah qoyska perfluorocarbon waxaana ugu horayn loo isticmaalaa warshadaha semiconductor iyo sida gaas aan shaqaynayn codsiyada kala duwan. Hoos waxaa ah qaar ka mid ah sifooyinka muhiimka ah ee octafluorocyclobutane:
Qalabka Jirka:
Muuqashada: Gaaska aan midabka lahayn ee heerkulka qolka iyo cadaadiska.
Barta karkarinta: Qiyaastii -38.1 °C (-36.6 °F).
Meesha dhalaalaysa: Qiyaastii -135.4 °C (-211.7 °F).
Cufnaanta: Ka sarreeya hawada, qiyaastii 5.1 g/L at 0 °C (32 °F) iyo 1 atm.
Solubility: Biyo ku milmi kara laakiin waxay ku milmi karaan qaar ka mid ah dareerayaasha organic.
Guryaha Kiimikada:
Xasilooni: Degganaanshaha xaaladaha caadiga ah, laakiin wuu qudhmi karaa marka ay la kulmaan heerkul aad u sarreeya ama iftiinka UV ee xooggan, oo suurtogal ah inuu sii daayo sunta iyo sunta sunta ah sida HF (hydrogen fluoride).
Falcelinta: Guud ahaan aan firfircoonayn oo leh walxaha ugu badan; si kastaba ha ahaatee, waxay si xun uga falcelin kartaa walxaha oksaydhaynta ee xooggan.
Adeegsada:
Warshadaha Semiconductor: Waxaa loo istcimaalaa sidii walax nadiifinta iyo nadiifinta ee hababka wax soo saarka semiconductor.
Codsiyada Caafimaadka: Waxaa loo isticmaalaa sidii wakiilka isbarbardhiga ee farsamooyinka sawirka caafimaadka sida ultrasound.
Gaaska Inert: Waxa loo isticmaalaa sidii gaas aan shaqaynayn codsiyo kala duwan halkaas oo jawi ka xor ah ogsijiinta loo baahan yahay.
Dabaylaha: Mararka qaarkood waxaa loo isticmaalaa sidii kicinta hawada hawada sare loo qaado taasoo ay ugu wacan tahay degenaanshihiisa iyo falcelintiisa hoose.
Saamaynta Deegaanka:
Gaaska cagaaran: Octafluorocyclobutane waa gaasta aqalka dhirta lagu koriyo oo awood leh oo leh awood kulayl caalami ah (GWP) muddo 100 sano ah.
Lakabka Ozone: Ma baabi'iyo lakabka ozone laakiin waxa uu si weyn uga qayb qaataa isbeddelka cimilada sababtoo ah cimrigiisa dheer ee hawada iyo GWP sare.
Alaab-qeybiyeyaal:
Markaad la tacaalayso octafluorocyclobutane, hubi inaad haysatid hawo habboon, xidho qalabka ilaalinta shakhsi ahaaneed ee habboon (PPE), oo aad marin u hesho hababka jawaabta degdegga ah. Had iyo jeer ku kaydi meel qabow oo qalalan oo ka fog alaabta iyo meelaha dabka laga shido.
