Hoʻolauna
ʻO ka 2-Fluoronicotinic acid he mea hoʻohuihui me ka ʻano kemika C6H4FNO2. He hua ia o ka waikawa nicotinic (3-oxopyridine-4-carboxylic acid) i loko o kona ʻano kemika, kahi i hoʻololi ʻia ai hoʻokahi hydrogen atom e kahi ʻātoma fluorine.
ʻO 2-Fluoronicotinic acid he paʻa keʻokeʻo keʻokeʻo i paʻa i ka mahana ambient. Hiki ke hoʻoheheʻe ʻia i ka wai. He ʻakika nāwaliwali ia e hana ai i nā paʻakai me nā metala.
Hoʻohana nui ʻia ka 2-Fluoronicotinic acid i kekahi mau kula. Hiki ke hoʻohana ʻia ma ke ʻano he waena koʻikoʻi i ka synthesis organik no ka hoʻomākaukau ʻana i nā pūhui ʻē aʻe a i ʻole nā lāʻau lapaʻau. Eia kekahi, hiki ke hoʻohana ʻia i loko o ka metala coordination chemistry a me nā hopena catalytic.
Aia nā ʻano hana like ʻole no ka hoʻomākaukau ʻana i ka 2-Fluoronicotinic acid. ʻO kahi ala maʻamau ma ka fluorination o ka waikawa nicotinic. ʻO ke ʻano maʻamau ka hopena o kahi mea hoʻopili fluorinating, e like me ka hydrogen fluoride a i ʻole trifluoroacetic acid, me ka waikawa nicotinic ma lalo o nā kūlana acidic e hāʻawi i ka 2-Fluoronicotinic acid.
Pono nā noʻonoʻo palekana i ka wā e lawelawe ai i ka 2-Fluoronicotinic acid. He mea ʻino ia a pono e hoʻohana ʻia me nā mīkina lima palekana a me nā aniani. Hōʻalo i ka hanu ʻana i ka lepo a i ʻole ka mahu i ka wā e hoʻohana ʻia ai, a mālama i kahi kaiapuni keʻena hoʻoheheʻe maikaʻi. I ka wā e mālama ai, pono e mālama ʻia i loko o kahi pahu maloʻo i hoʻopaʻa ʻia, ma kahi mamao o nā mea puhi a me nā oxidants.
Ma keʻano laulā, ʻo ka 2-Fluoronicotinic acid he hui kūlohelohe me ka solubility maikaʻi a me ke kūpaʻa. Loaʻa iā ia ka laulā o nā noi i ka synthesis organik, ka hoʻohui metala a me nā hopena catalytic, akā pono e mālama ʻia nā pale palekana i ka wā o ka mālama ʻana a me ka mālama ʻana.
