ʻO ka 2-Hydroxy-3-nitro-6-methylpyridine kahi mea hoʻohuihui me ke ʻano kemika C7H7N2O3. Eia ka wehewehe kikoʻī o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.

 

ʻAno:

-Nani: 2-hydroxy-3-nitro-6-methylpyridine he keʻokeʻo i ka pauka crystalline melemele māmā.

-Solubility: haʻahaʻa kona solubility i ka wai, hiki ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe organik e like me ka waiʻona, ether, ketone, etc.

-Ka helu hoʻoheheʻe: ʻO ka helu heheʻe o kēia pūhui ma kahi o 194-198 ° C.

-Stability: paʻa paʻa i ka lumi wela, akā pono e pale i ka ʻike ʻana i ka mālamalama a me ke kiʻekiʻe o ka mahana wela.

 

E hoʻohana:

-2-hydroxy-3-nitro-6-methylpyridine ka mea maʻamau i hoʻohana ʻia ma ke ʻano he waena i ka synthesis organik a hoʻohana ʻia i ka synthesis o nā pūhui ʻē aʻe.

-Hiki nō hoʻi ke hoʻohana ʻia i ka hoʻomākaukau ʻana i nā mea kōkua hoʻoponopono lāʻau, pesticides, pharmaceuticals a me nā mea hoʻonaninani a me nā māla ʻē aʻe.

 

Hanana:

-2-Hydroxy-3-nitro-6-methylpyridine ka mea maʻamau e loaʻa i ka synthesis kemika. Hiki ke loaʻa ke ʻano kikoʻī ma ka hana ʻana i ka 3-methylpyridine me ka waikawa nitric ma o ka hopena nitration, a laila ma o ka hoʻohaʻahaʻa a me ka hopena hydroxylation.

 

ʻIke palekana:

ʻO -2-hydroxy-3-nitro-6-methylpyridine he mea kemika me kekahi mea ʻona. E hahai i nā kaʻina hana palekana lab i ka wā e hana ai.

- Hiki i ka hoʻopili ʻana a i ʻole ka inhalation o kēia pūhui ke hoʻonāukiuki a hōʻeha i ke kino o ke kanaka. Pono e pale ʻia ka pili ʻana i ka ʻili, ka inhalation a me ka ʻai ʻana. Pono e hoʻohana ʻia nā mīkina lima pale ʻoihana, ka maka a me nā mea hanu i ka wā e hoʻohana ai.

-Inā pili me ka ʻili a i ʻole nā ​​maka, holoi koke me ka wai nui a ʻimi koke i ka ʻōlelo aʻoaʻo olakino.

- Pono e mālama ʻia ka mea hoʻohui i kahi i hoʻopaʻa ʻia, maloʻo, maikaʻi-ventilated, mamao mai ke ahi a me nā mea oxidizing. Ke hoʻolei ʻana i ka ʻōpala, e hahai i nā lula hoʻomalu kaiapuni kūloko.
