Hoʻolauna

2-Chloropyridine-6-carboxylic acid, i ʻike ʻia ʻo 2-Chloro-6-pyridinecarboxylic acid.

 

ʻAno maikaʻi:

ʻO 2-Chloropyridine-6-carboxylic acid kahi paʻa keʻokeʻo keʻokeʻo me kahi ʻala kūikawā. Hiki ke hoʻoheheʻe ʻia i loko o ka waiʻona, ketone a me nā solvents ether a hiki ke hoʻoheheʻe iki ʻia i ka wai.

 

E hoʻohana:

Hiki ke hoʻohana ʻia ka 2-Chloropyridine-6-carboxylic acid ma ke ʻano he waena i ka synthesis o nā mea hoʻohui.

 

Hanana:

Hiki ke kiʻi ʻia ka hoʻomākaukau ʻana o 2-chloropyridine-6-carboxylic acid ma ka hana ʻana i ka 2-chloropyridine me ka chlorine i mua o kahi mea hoʻoheheʻe waiʻona. ʻO ke ʻano hoʻomākaukau kūikawā penei:

Ma lalo o ke kūlana o ka hoʻomehana wela mau, hoʻopili ʻia ka 2-chloropyridine me ka chlorine, a loaʻa ka huahana (2-chloropyridine-6-carboxylic acid) ma hope o ka hopena.

 

ʻIke palekana:

ʻO ka 2-Chloropyridine-6-carboxylic acid he mea palekana ma lalo o nā kūlana hana maʻamau, akā pono e mālama ʻia. I ka wā o ka hoʻohana ʻana, e pale i ka hoʻopili ʻana me ka ʻili a me nā maka, a e hōʻoia i ka hana ʻia ʻana o ka hana ma kahi wahi i hoʻoluʻu maikaʻi ʻia. Inā pilikia, holoi koke me ka wai nui a ʻimi i ka lāʻau lapaʻau.

I ka hoʻohana ʻana a me ka lawelawe ʻana i nā kemika, pono e hahai i nā hana hoʻokolohua kūpono a me nā hana pale pilikino e hōʻoia i ka palekana a me ka palekana o ke kaiapuni.
