ʻO 2-Bromo-6-chloropyridine he mea hoʻohuihui.

 

ʻAno maikaʻi:

ʻO 2-Bromo-6-chloropyridine kahi paʻa keʻokeʻo keʻokeʻo me ka ʻono ʻawaʻawa a me kahi ala ʻala ikaika. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai ma ka lumi wela, akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol, ether a me benzene. Loaʻa iā ia ka paʻa wela a me ke kemika.

 

E hoʻohana:

Ma ke ʻano he kikowaena kūlohelohe, 2-bromo-6-chloropyridine ka nui o nā noi i ka synthesis kemika. Eia kekahi, hiki ke hoʻohana ʻia e like me ka catalyst, solvent a me reagent, etc.

 

Hanana:

Hoʻomākaukau ʻia ka 2-Bromo-6-chloropyridine e nā ʻano hana synthesis. ʻO ke ala maʻamau ka hana ʻana i ka 2-chloro-6-bromopyridine me ka thionyl chloride a i ʻole dimethyl sulfate a hoʻomehana iā ia ma lalo o nā kūlana alkaline e hana i ka 2-bromo-6-chloropyridine.

 

ʻIke palekana:

ʻO ka 2-Bromo-6-chloropyridine he mea hoʻohuihui kino i loaʻa kekahi mea ʻona i ke kanaka. I ka wā o ka hoʻohana ʻana, pono e ʻalo ʻia ka pili pono ʻana me ka ʻili a me nā maka e pale aku ai i ka inhalation a i ʻole ka ʻai ʻana. Pono e hana ma kahi e hoʻoheheʻe maikaʻi ʻia a hoʻokomo i nā lako pale pilikino kūpono e like me nā mīkina lima, nā maka aniani, a me nā lole pale. Inā ʻike ʻia kēia pūhui, holoi koke me ka wai nui a ʻimi koke i ka lāʻau lapaʻau. I ka wā o ka mālama ʻana a me ka lawe ʻana, pono e pale ʻia ka hoʻopili ʻana me nā lapalapa ākea, nā kumu wela a me nā mea ʻona e pale aku i nā pōʻino ahi a pahū.
