3-Nitro-2-pyridinol (CAS# 6332-56-5)

Isingeniso

I-2-Hydroxy-3-nitropyridine iyinhlanganisela ye-organic ene-molecular formula C5H4N2O3 kanye ne-structural formula HO-NO2-C5H3N.

Imvelo:

I-2-Hydroxy-3-nitropyridine iyikristalu ephuzi engancibilika kwezinye izinyibilikisi zemvelo ezifana ne-ethanol ne-dimethylformamide. Inephuzu eliphansi lokuncibilika kanye nokubilisa.

Sebenzisa:

I-2-Hydroxy-3-nitropyridine ivamise ukusetshenziswa ekuphenduleni kwe-organic synthesis, njengama-reagents noma izinto zokusetshenziswa. Ingabamba iqhaza ezinhlobonhlobo zokusabela kwamakhemikhali, njengokusabela kokunciphisa nokusabela kwe-esterification.

Indlela Yokulungiselela:

Ukulungiswa kwe-2-Hydroxy-3-nitropyridine ngokuvamile kungatholwa ngokusabela kwe-nitration. Okokuqala, i-pyridine isabela nge-nitric acid egxilile ukuze yakhe i-2-nitropyridine. I-2-Nitropyridine bese isabela ngesisekelo esigxilile ukuze yakhe i-2-Hydroxy-3-nitropyridine.

Ulwazi Lokuphepha:

I-2-Hydroxy-3-nitropyridine iyikhemikhali futhi kufanele isetshenziswe ngokuphepha. Kungase kucasule amehlo, isikhumba kanye nomgudu wokuphefumula. Ukuthintana nokuphefumula kwe-compound kufanele kugwenywe ngesikhathi sokusebenza. Sebenzisa izinto zokuzivikela ezifana namagilavu ​​okuvikela amakhemikhali kanye nezibuko lapho uzisebenzisa. Ngaphezu kwalokho, ukusebenza kufanele kwenziwe endaweni enomoya omuhle ukuze kuqinisekiswe ukuphepha.
