Hoʻolauna
5-Bromo-2-ethoxypyridine. ʻO kāna mau waiwai nui penei:
ʻIke: 5-bromo-2-ethoxypyridine he paʻa keʻokeʻo keʻokeʻo.
Solubility: hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik, e like me ka ethanol, ether, etc., insoluble in water.
Hiki ke hoʻohana ʻia e like me ka brominating reagent no ka oxidation reactions, halogenation reactions, a me ka condensation reactions, i waena o kekahi.
ʻO nā ala nui no ka hoʻomākaukau ʻana i ka 5-bromo-2-ethoxypyridine penei:
Ka hopena o ka waiʻona 5-bromo-2-pyridine me ka ethanol: Hoʻopili ʻia ka 5-bromo-2-pyridinol me ka ethanol ma lalo o ka catalysis acid e hana ai i ka 5-bromo-2-ethoxypyridine.
ʻO ka pane o 5-bromo-2-pyridine me ka ethanol: 5-bromo-2-pyridine i hoʻopili ʻia me ka ethanol ma lalo o ka catalysis alkali e hana ai i ka 5-bromo-2-ethoxypyridine.
ʻO ka 5-Bromo-2-ethoxypyridine he mea hoʻohuihui me nā mea ʻona, a pono e hana ʻia me nā mīkina lima pale a me nā aniani.
Hōʻalo i ka hanu ʻana, nau, a ʻai ʻole i ka hui a pale i ka pili ʻana me ka ʻili.
I ka mālama ʻana, pono e hoʻopaʻa ʻia a mālama ʻia mai ke ahi a me nā oxidants.
Holoi ʻōpala: E hoʻolei iā ia e like me nā lula kūloko a pale i ka hoʻolei ʻana ma ka makemake.
