CAS Helu 115-25-3 Octafluorocyclobutane Mea Hoʻolako. Nā hiʻohiʻona o Octafluorocyclobutane
ʻO Octafluorocyclobutane, ka mea i ʻike ʻia he perfluorocyclobutane a i ʻole PFCB, loaʻa ke ʻano kemika C4F8 a me ka helu CAS 115-25-3. He lālā kēia pūhui o ka ʻohana perfluorocarbon a hoʻohana nui ʻia i ka ʻoihana semiconductor a ma ke ʻano he kinoea inert i nā noi like ʻole. Aia ma lalo iho kekahi mau hiʻohiʻona nui o ka octafluorocyclobutane:
Nā waiwai kino:
'Ike: kinoea kala ole ma ka lumi wela a me ke kaomi.
Lae paila: Ma kahi o −38.1 °C (−36.6 °F).
Lae hehee: Ma kahi o −135.4 °C (−211.7 °F).
ʻOi aku ka nui ma mua o ka ea, ma kahi o 5.1 g/L ma 0 °C (32 °F) a me 1 atm.
Solubility: ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai akā hiki ke hoʻoheheʻe ʻia i loko o kekahi mau mea hoʻoheheʻe organik.
Nā waiwai kemika:
Paʻa: Paʻa ma lalo o nā kūlana maʻamau akā hiki ke hoʻoheheʻe ke ʻike ʻia i nā wela kiʻekiʻe loa a i ʻole ke kukui UV ikaika, hiki ke hoʻokuʻu i nā kinoea ʻona a me nā kinoea ʻino e like me HF (hydrogen fluoride).
Hoʻohuʻi: ʻAʻole hoʻokō me ka nui o nā mea maʻamau; akā naʻe, hiki iā ia ke hana ikaika me nā mea hoʻoheheʻe ikaika.
Hoʻohana:
ʻOihana Semiconductor: Hoʻohana ʻia ma ke ʻano he etchant a me ka mea hoʻomaʻemaʻe i nā kaʻina hana semiconductor.
Nā Lapaʻau Lapaʻau: Hoʻohana ʻia ma ke ʻano he mea ʻokoʻa i nā ʻenehana kiʻi lapaʻau e like me ultrasound.
Inert Gas: Hoʻohana ʻia e like me ke kinoea inert i nā noi like ʻole kahi e koi ʻia ai kahi kaiapuni ʻole oxygen.
Propellant: I kekahi manawa hoʻohana ʻia e like me ka propellant i nā aerosol ma muli o kona kūpaʻa a me ka haʻahaʻa haʻahaʻa.
Ka hopena o ke kaiapuni:
ʻO ke kinoea hale ʻōmaʻomaʻo: ʻO Octafluorocyclobutane he kinoea hoʻomehana honua ikaika me ka hiki ke hoʻomehana honua kiʻekiʻe (GWP) ma kahi o 100 mau makahiki.
Ozone Layer: ʻAʻole ia e hoʻopau i ka papa ozone akā kōkua nui i ka hoʻololi ʻana i ke aniau ma muli o kona ola lōʻihi o ka lewa a me ka GWP kiʻekiʻe.
Nā mea hoʻolako:
I ka lawelawe ʻana i ka octafluorocyclobutane, e hōʻoia e loaʻa iā ʻoe ka ea kūpono, e hoʻohana i nā lako pale pilikino (PPE) kūpono, a loaʻa iā ʻoe nā kaʻina hana pane pilikia. E mālama mau iā ia ma kahi maloʻo maloʻo ma kahi mamao mai nā mea like ʻole a me nā kumu e hoʻā ai.
