Taw qhia
2,4-Dihydroxypyridine hmoov. Nws muaj cov khoom nram qab no:
Cov tsos mob: 2,4-Dihydroxypyridine yog dawb crystalline khoom.
Solubility: Nws muaj solubility zoo thiab soluble hauv dej thiab ntau yam organic solvents.
Ligand: Raws li lub ligand rau kev hloov pauv hlau complexes, 2,4-dihydroxypyridine tuaj yeem tsim cov complexes ruaj khov nrog cov hlau, uas yog siv dav hauv kev npaj cov catalysts thiab cov organic synthesis tseem ceeb.
Corrosion inhibitor: Nws yog siv los ua ib qho ntawm cov khoom siv hlau corrosion inhibitors, uas tuaj yeem tiv thaiv cov hlau nto ntawm corrosion.
Txoj kev npaj ntawm 2,4-dihydroxypyridine yog raws li nram no:
Hydrocyanic acid cov tshuaj tiv thaiv txoj kev: 2,4-dichloropyridine yog reacted nrog hydrocyanic acid kom tau 2,4-dihydroxypyridine.
Hydroxylation cov tshuaj tiv thaiv: 2,4-dihydroxypyridine yog tsim los ntawm cov tshuaj tiv thaiv pyridine thiab hydrogen peroxide nyob rau hauv lub platinum catalyst.
Cov ntaub ntawv kev nyab xeeb: 2,4-Dihydroxypyridine yog cov tshuaj lom neeg thiab yuav tsum tau siv ceev faj:
Toxicity: 2,4-Dihydroxypyridine yog tshuaj lom nyob rau hauv tej yam concentrations thiab tej zaum yuav ua rau khaus ntawm lub qhov muag thiab tawv nqaij thaum sib cuag. Kev sib cuag ncaj qha nrog thiab nqus tau nws cov hmoov av yuav tsum zam.
Cia: 2,4-Dihydroxypyridine yuav tsum muab cia rau hauv qhov chaw qhuav, txias kom tsis txhob muaj oxidants thiab muaj zog acids. Thaum lub sij hawm cia, yuav tsum tau them nyiaj rau kev tiv thaiv noo noo kom tsis txhob deteriorating vim ya raws.
Kev pov tseg pov tseg: Tsim nyog pov tseg cov khoom pov tseg, yuav tsum ua raws li cov cai thiab cov cai hauv zos, kom tsis txhob muaj kuab paug ib puag ncig.
Thaum siv 2,4-dihydroxypyridine, cov txheej txheem kev nyab xeeb muaj feem xyuam thiab kev tiv thaiv tus kheej, xws li hnav hnab looj tes thiab tsom iav, yuav tsum tau ua raws li kev siv nyab xeeb.
