Hoʻolauna
ʻO 5-Bromo-2-methylpyridine kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka pūhui:
ʻAno maikaʻi:
ʻO ke ʻano: 5-bromo-2-methylpyridine he aniani melemele ʻole a ʻeleʻele paha.
Solubility: Hiki ke hoʻoheheʻe ʻia i loko o ka hapa nui o nā mea hoʻoheheʻe organik a he haʻahaʻa haʻahaʻa i ka wai.
E hoʻohana:
Catalyst: Hiki ke hoʻohana ʻia ma ke ʻano he catalyst no kekahi mau hopena catalyzed.
Hanana:
ʻO kahi ala maʻamau no ka hoʻomākaukau ʻana i ka 5-bromo-2-methylpyridine ma ka brominated 2-methylpyridine. ʻO nā ʻanuʻu kikoʻī penei:
Hoʻoheheʻe ʻia ʻo 2-methylpyridine i ka solvent.
Hoʻohui ʻia kahi mea hana brominating, e like me ka wai bromine a i ʻole mercuric chloride, i ka hopena e hana i ka 5-bromo-2-methylpyridine.
E kānana a crystallize no ka loaʻa ʻana o kahi huahana maʻemaʻe.
ʻIke palekana:
ʻO 5-Bromo-2-methylpyridine kahi hui organobromine a pono e mālama ʻia me ka mālama pono e pale aku i ka pili ʻana me ka ʻili, nā maka a me ka ʻōpū hanu.
E hōʻalo i ka hanu ʻana i kāna pauda a i ʻole nā huhū i hana ʻia.
Pono e hoʻohana ʻia nā mīkina lima pale kūpono, nā aniani palekana a me nā pale pale i ka wā o ka hana.
I ka hoʻohana ʻana a mālama ʻana paha, pono e mālama ʻia mai ka ʻāʻī a me nā oxidants.
I ka lawelawe ʻana i ka 5-bromo-2-methylpyridine, pono e mālama ʻia nā kaʻina hana palekana a mālama ʻia i loko o kahi ea maikaʻi.
