Mawu Oyamba
2-Methoxy-3-methylpyrazine (yomwe imadziwikanso kuti methoxylate) ndi mankhwala achilengedwe. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:
Ubwino:
- Maonekedwe: Melafenone ndi kristalo wachikasu wonyezimira kapena wonyezimira wopanda utoto.
- Kusungunuka: Simasungunuka mosavuta m'madzi, koma amasungunuka mu zosungunulira za organic monga ethanol ndi chloroform.
Gwiritsani ntchito:
Njira:
Pali njira zingapo zopangira melafenone, ndipo zofala zimaphatikizapo izi:
- kaphatikizidwe ndi makutidwe ndi okosijeni anachita: 2-methoxy-3-methylpyridine anachita ndi zinki kolorayidi, ndiyeno acidified ndi asidi kupeza methrafenone.
- Kaphatikizidwe ndi kusintha kosinthika: Methoxy-3-methylpyridine imayendetsedwa ndi cholowa (monga methyl iodide) pansi pa alkali catalysis kuti ipeze methrenone.
Zambiri Zachitetezo:
- Melafenone ndi mankhwala ndipo ali ndi zoopsa zina.
- Pewani kutulutsa fumbi, kukhudza khungu ndi maso, komanso kupewa kudya.
- Valani magolovesi oteteza ndi magalasi kuti muzitha mpweya wabwino.
- Zinyalala ziyenera kutayidwa motsatira malamulo a chilengedwe.
