I-2-Amino-3-hydroxypyridine (CAS # 16867-03-1) intshayelelo

I-2-Amino-3-hydroxypyridine. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:

Umgangatho:
I-2-Amino-3-hydroxypyridine yikhompawundi ephilayo enembonakalo emhlophe yekristale enyibilikayo emanzini kunye nezinye izinyibilikisi eziphilayo.
Isiseko esomeleleyo esenza i-asidi ingathathi hlangothi kwaye yenza iityuwa ezihambelanayo. Ine-pH ephezulu kwaye isoloko isetyenziswa kwi-neutralization reactions.

Usetyenziso: Isenokusetyenziswa ekulungiseleleni iintlobo ngeentlobo zeemveliso zeekhemikhali ezifana nedayi, iingubo, kunye nezithambiso.

Indlela:
Ukulungiswa kwe-2-amino-3-hydroxypyridine ngokubanzi kuqala kwi-pyridine. Okokuqala, i-pyridine iphendulwa ngegesi ye-ammonia ukwenza i-2-aminopyridine. Emva koko, phambi kwe-sodium hydroxide, ukuphendulwa kwenziwa ukwenza i-2-amino-3-hydroxypyridine.

Ulwazi ngoKhuseleko:
I-2-Amino-3-hydroxypyridine inokuba nefuthe elicaphukisayo emehlweni, ulusu kunye nenkqubo yokuphefumla. Ngexesha lokusetyenziswa, nceda ugcine imilinganiselo yokukhusela efanelekileyo, njengokunxiba iiglavu, iiglasi zokhuseleko, njl njl. Nceda ugcine i-compound ngokufanelekileyo, kude nomlilo kunye nezinto ezinokutsha.
