Nhanganyaya
2,4-Dihydroxypyridine. Iine zvinhu zvinotevera:
Kuonekwa: 2,4-Dihydroxypyridine ichena crystalline yakasimba.
Solubility: Ine yakanaka solubility uye inonyungudika mumvura uye zvakasiyana siyana zveorganic solvents.
Ligand: Se ligand yekushandura metal complexes, 2,4-dihydroxypyridine inogona kuumba yakagadzikana yakaoma nesimbi, iyo inoshandiswa zvakanyanya mukugadzirwa kwezvinokonzera uye zvakakosha organic synthesis reactions.
Corrosion inhibitor: Inoshandiswa seimwe yezvikamu zvesimbi corrosion inhibitors, iyo inogona kunyatso chengetedza nzvimbo dzesimbi kubva mukuora.
Nzira yekugadzirira ye2,4-dihydroxypyridine ndeyotevera:
Hydrocyanic acid reaction method: 2,4-dichloropyridine inobatwa ne hydrocyanic acid kuti iwane 2,4-dihydroxypyridine.
Hydroxylation reaction method: 2,4-dihydroxypyridine inogadzirwa nekuita kwepyridine uye hydrogen peroxide pasi peplatinum catalyst.
Ruzivo Rwekuchengetedza: 2,4-Dihydroxypyridine ikemikari uye inofanira kushandiswa nekuchenjerera:
Toxicity: 2,4-Dihydroxypyridine ine chepfu pane dzimwe nzvimbo uye inogona kukonzera kutsamwa kumaziso uye ganda kana yabatwa. Kusangana kwakananga nekufema kweguruva rayo kunofanira kudziviswa.
Kuchengetedza: 2,4-Dihydroxypyridine inofanira kuchengetwa munzvimbo yakaoma, inotonhorera kuti isasangana neoxidants uye yakasimba acids. Panguva yekuchengetera, kutarisisa kunofanirwa kubhadharwa kune kuchengetedzwa kwemwando kudzivirira kubva pakuipa nekuda kwekunyorova.
Kurasa tsvina: Kurasa tsvina zvine musoro, kunofanira kutevedzera mitemo nemirau yezvakatipoteredza, kudzivirira kusvibiswa kwezvakatipoteredza.
Paunenge uchishandisa 2,4-dihydroxypyridine, maitiro ekuchengetedza akakodzera uye matanho ekudzivirira ega, sekupfeka magirovhosi nemagirazi, anofanirwa kuteverwa kuti ave nechokwadi chekushandiswa kwakachengeteka.
