Hoʻolauna

ʻO ka 2-Hydroxy-3-nitropyridine he mea hoʻohui kino me ke ʻano mole mole C5H4N2O3 a me ke kumu hoʻohālike HO-NO2-C5H3N.

ʻAno:

ʻO 2-Hydroxy-3-nitropyridine he aniani melemele e hiki ke hoʻoheheʻe ʻia i kekahi mau mea hoʻoheheʻe kūlohelohe e like me ka ethanol a me ka dimethylformamide. He haʻahaʻa kona helu heheʻe a me ka paila.

E hoʻohana:

Hoʻohana maʻamau ʻia ka 2-Hydroxy-3-nitropyridine i nā hopena synthesis organik, e like me nā reagents a i ʻole nā ​​​​mea maka. Hiki iā ia ke komo i nā ʻano hana kemika, e like me ka ho'ēmi ʻana a me ka hopena esterification.

Kaʻina hoʻomākaukau:

ʻO ka hoʻomākaukau ʻana i ka 2-Hydroxy-3-nitropyridine hiki ke loaʻa ma ke ʻano he hopena nitration. ʻO ka mua, hoʻopili ʻia ka pyridine me ka waikawa nitric concentrated e hana i ka 2-nitropyridine. Hoʻopili ʻia ʻo 2-Nitropyridine me ka base concentrated e hana i ka 2-Hydroxy-3-nitropyridine.

ʻIke palekana:

ʻO ka 2-Hydroxy-3-nitropyridine he mea kemika a pono e hoʻohana pono ʻia. He mea hoʻonāukiuki paha i ka maka, ka ʻili a me ka ʻōpū hanu. Pono e pale ʻia ka hoʻopili ʻana a me ka inhalation o ka hui i ka wā o ka hana. E hoʻohana i nā mea pale pilikino e like me nā mīkina lima pale kemika a me nā maka aniani ke hoʻohana iā lākou. Eia kekahi, pono e hoʻokō ʻia ka hana ma kahi wahi e pono ai ka palekana.
