Isingeniso
2,4-Dihydroxypyridine. Inezici ezilandelayo:
Ukubukeka: I-2,4-Dihydroxypyridine iyi-crystalline solid solid.
I-Solubility: Inokuncibilika okuhle futhi iyancibilika emanzini kanye nezinhlobonhlobo zezincibilikisi eziphilayo.
I-Ligand: Njenge-ligand ye-transition metal complexes, i-2,4-dihydroxypyridine ingakha izakhiwo ezizinzile ezinensimbi, ezisetshenziswa kabanzi ekulungiseleleni ama-catalysts kanye nokusabela okubalulekile kwe-organic synthesis.
I-Corrosion inhibitor: Isetshenziswa njengenye yezingxenye ze-metal corrosion inhibitors, ezingavikela ngempumelelo izindawo zensimbi ekugqwaleni.
Indlela yokulungiselela i-2,4-dihydroxypyridine imi kanje:
Indlela yokusabela ye-Hydrocyanic acid: I-2,4-dichloropyridine isabela nge-hydrocyanic acid ukuze ithole i-2,4-dihydroxypyridine.
Indlela yokusabela nge-Hydroxylation: I-2,4-dihydroxypyridine ikhiqizwa ukusabela kwe-pyridine ne-hydrogen peroxide ngaphansi kwe-platinum catalyst.
Ulwazi Lokuphepha: I-2,4-Dihydroxypyridine iyikhemikhali futhi kufanele isetshenziswe ngokuqapha:
Ubuthi: I-2,4-Dihydroxypyridine inobuthi ezindaweni ezithile futhi ingase ibangele ukucasuka emehlweni nasesikhumbeni lapho ithintwa. Ukuthintana ngqo nokuhogela uthuli lwayo kufanele kugwenywe.
Isitoreji: I-2,4-Dihydroxypyridine kufanele igcinwe endaweni eyomile, epholile ukugwema ukuthintana nama-oxidants nama-acids aqinile. Ngesikhathi sokugcinwa, ukunakwa kufanele kukhokhwe ekuvikeleni umswakama ukuze uvimbele ukuwohloka ngenxa yomswakama.
Ukulahlwa kwemfucuza: Ukulahlwa kwemfucuza ngendlela ephusile, kufanele kuhambisane nemithetho nemithethonqubo yendawo yendawo, ukuze kugwenywe ukungcoliswa kwemvelo.
Uma usebenzisa i-2,4-dihydroxypyridine, izinqubo ezifanele zokusebenza zokuphepha kanye nezinyathelo zokuzivikela, njengokugqoka amagilavu nezibuko, kufanele zilandelwe ukuze kuqinisekiswe ukusetshenziswa okuphephile.
