Mawu Oyamba
Ndi organic pawiri ndi mankhwala chilinganizo C7H7N2O3. Zotsatirazi ndizofotokozera za katundu, ntchito, kukonzekera ndi chitetezo cha pawiri:
Chilengedwe:
-Maonekedwe: Ndi kristalo wachikasu kapena ufa.
-Kusungunuka: Imasungunuka m'madzi ndipo imasungunuka mosavuta mu zosungunulira za organic monga ethanol, chloroform ndi dimethyl sulfoxide.
- Malo osungunuka: Malo ake osungunuka ndi pafupifupi 135-137 madigiri Celsius.
-Chemical properties: Ndi chinthu chonunkhira chomwe chili ndi nayitrogeni komanso zochita zina za mankhwala.
Gwiritsani ntchito:
-Itha kugwiritsidwa ntchito ngati wapakatikati pakupanga zinthu zina zakuthupi.
-Itha kugwiritsidwa ntchito ngati mankhwala ophera tizilombo komanso mankhwala ophera udzu m'munda waulimi.
Njira:
- ikhoza kukonzedwa pochita 2-methylpyridine ndi nitric acid. Masitepe enieni ndi awa: Kusungunula 2-methylpyridine mu Mowa, kuwonjezera asidi nitric, ndi kupeza mankhwala mwa crystallization pambuyo anachita.
Zambiri Zachitetezo:
-Zowopsa kwambiri mukakumana ndi khungu, pokoka mpweya kapena mukameza.
-Pewani kukhudzana ndi khungu komanso kutulutsa mpweya mukakumana. Valani magalasi ndi magolovesi ngati kuli kofunikira.
-Yang'anirani njira zoyendetsera ntchito zotetezeka mukamagwira ndikusunga ndikusindikiza bwino.
-ngati kuli kofunikira, onetsani ku Chemical Safety Data Sheet (MSDS) kuti mudziwe zambiri zachitetezo.
