Mawu Oyamba
2-methyll-5-nitropyridine ndi organic pawiri ndi mankhwala chilinganizo C6H6N2O2, amene ali katundu zotsatirazi:
1. Maonekedwe: kristalo wopanda mtundu mpaka kuwala wachikasu;
2. Kununkhira: palibe fungo lapadera;
3. Malo osungunuka: 101-104 madigiri Celsius;
4. Kusungunuka: pafupifupi kosasungunuka m'madzi, kusungunuka mu zosungunulira za organic monga ethanol ndi dichloromethane.
2-Methyl-5-nitropyridine amagwiritsidwa ntchito makamaka ngati zopangira komanso zapakatikati mu kaphatikizidwe ka organic ndi makampani opanga mankhwala. Ikhoza kugwiritsidwa ntchito popanga mankhwala a pyridine ndi thiophene, komanso angagwiritsidwe ntchito pokonzekera mankhwala ophera tizilombo, utoto ndi mankhwala enaake m'munda wamankhwala.
Kukonzekera kwa 2-methyll-5-nitropyridine kumatha kuchitika ndi izi:
1.2-pyridine asidi acetic ndi sodium nitrite anachita pansi acidic mikhalidwe kupanga 2-nitropyridine.
2. Zomwe 2-Nitro pyridine ndi methylating reagent (monga methyl iodide) kupanga 2-Methyl-5-nitropyridine.
Mukamagwiritsa ntchito ndikusunga 2-methyll-5-nitropyridine, muyenera kulabadira izi:
-Ndi choyaka, kupewa kukhudzana ndi moto;
- Samalirani njira zodzitetezera panthawi yogwira ntchito, monga kuvala magalasi oteteza ndi magolovesi;
- kupewa inhalation ake mpweya kapena fumbi, kupewa khungu kukhudzana;
- Sungani mu chidebe chotsekedwa, kutali ndi moto ndi oxidizing agents;
- Pewani kusakaniza ndi ma oxidants amphamvu kapena ma asidi amphamvu.
