Mawu Oyamba
Ndi organic pawiri ndi mankhwala chilinganizo C8H9NO3. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
-Maonekedwe: Ndiwopanda mtundu mpaka wopepuka wachikasu wonyezimira.
-Kusungunuka: Kumasungunuka m'madzi, koma kumasungunuka bwino mu zosungunulira za organic monga ethanol ndi dimethylformamide.
- Malo osungunuka: Malo osungunuka ndi pafupifupi 72-75 digiri Celsius.
Gwiritsani ntchito:
-Chemical kaphatikizidwe: Ndiwogwiritsidwa ntchito nthawi zambiri wapakati omwe angagwiritsidwe ntchito popanga zinthu zina za organic.
-Research: Itha kugwiritsidwa ntchito popanga ma organic synthesis ndi kafukufuku wina wa labotale.
Njira Yokonzekera:
Synthesis imatha kuchitika m'njira zotsatirazi:
1. Choyamba, 2-methyloxy-5-nitropyridine imapezeka pochita 2-methyloxy-5-nitropyridine ndi nitric acid.
2. Kenaka muzichita 2-methoxy-5-nitropyridine ndi methylating reagent (monga methyl sodium iodide) kuti mupeze mankhwala omaliza.
Zambiri Zachitetezo:
Zotetezedwa ndizochepa, koma zitha kukhala zoopsa kwa anthu komanso chilengedwe. Pogwiritsira ntchito, tsatirani ndondomeko yoyenera ya labotale, ndikuchitapo kanthu zodzitetezera, monga kuvala magalasi oteteza ndi magolovesi. Kuphatikiza apo, pawiriyo iyenera kusungidwa ndikutayidwa moyenera kuti zisaipitsidwe ndi chilengedwe.
