CAS Helu 7637-7-2 Boron Fluoride Mea Hoʻolako. Nā ʻano o ka Boron Fluoride

ʻO Boron trifluoride (BF₃) he mea hoʻohui kemika i hoʻohana nui ʻia i loko o ka ʻoihana kemika, ʻoi aku hoʻi ma ke ʻano he catalyst i ka synthesis organik a ma ke ʻano he reagent i nā hopena kemika. Loaʻa iā ia ka helu CAS 7637-7-2. Eia kekahi mau hiʻohiʻona nui o ka boron trifluoride:

Nā waiwai kino:
Nānā: Ke kinoea kala ʻole ma lalo o nā kūlana maʻamau.
Puni paila: -100.3°C (-148.5°F).
Lae hehee: -127.2°C (-196.9°F).
Māmā: 2.88 g/L ma 20°C.
Hiki ke hoʻoheheʻe ʻia i ka wai: hiki ke hoʻoheheʻe ʻia me ka wai e hana i ka waikawa boric a me ka waika hydrofluoric.
Nā waiwai kemika:
Reactivity: Kiʻekiʻe loa me ka wai, nā waiʻona, a me nā nucleophiles ʻē aʻe.
Kaʻakika: Hana ʻo BF₃ ma ke ʻano he ʻakika Lewis ma muli o kāna ʻātoma boron hemahema electron.
ʻAʻawaʻawa: Hiki ke pōʻino inā inhaled, moni ʻia, a pili pū me ka ʻili a me nā maka. He mea ʻino ia a hiki ke hana i nā kuni ʻino.
Hoʻohana:
Catalysis: Hoʻohana mau ʻia ma ke ʻano he catalyst i nā hopena Friedel-Crafts a me nā hopena synthesis organik ʻē aʻe.
Etching Agent: Hoʻohana ʻia i ka hana semiconductor no ka etching silicon dioxide.
Nā hopena o ka fluorination: hoʻohana ʻia i ka hoʻomākaukau ʻana i nā pūhui fluorinated.
Analytical Chemistry: Hoʻohana ʻia i ka chromatography kinoea ma ke ʻano he reagent no ka derivatization o nā amine.
I ka lawelawe ʻana i ka boron trifluoride, pono e lawe ʻia nā ʻano palekana kūpono ma muli o kona ʻona a me ka hana ʻana. Hoʻopili kēia i ka hoʻohana ʻana i nā mea pale pilikino e like me nā mīkina lima, nā maka aniani, a me ka pale maka, ka hana ʻana ma kahi wahi e hoʻoheheʻe maikaʻi ʻia a i ʻole ka pahu hau, a me ka hahai ʻana i nā alakaʻi palekana kūpono.
