Mawu Oyamba
N-Methyl-4-chloropyridine-2-carboxamide ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, njira zopangira ndi chitetezo:
Ubwino:
N-methyl-4-chloropyridine-2-carboxamide ndi woyera crystalline kapena crystalline ufa ndi fungo lapadera. Ili ndi kusungunuka kwabwino komanso kusungunuka kwakukulu m'madzi. Ili ndi chikhalidwe cha acidic chochepa mpaka champhamvu.
Kagwiritsidwe: Kuphatikiza apo, itha kugwiritsidwanso ntchito ngati chopangira choteteza mbewu ndi mankhwala ophera tizilombo.
Njira:
N-methyl-4-chloropyridine-2-carboxamide ikhoza kukonzedwa ndi methylation ya 4-chloropyridin-2-carboxamide. Njira za kaphatikizidwe zinazake zitha kusinthidwa ndikuwongoleredwa ngati pakufunika.
Zambiri Zachitetezo:
Kugwiritsa ntchito ndi kusamalira N-methyl-4-chloropyridin-2-carboxamide kumafuna kutsata ndondomeko zoyenera zotetezera. Ndi organic pawiri ndipo sayenera kukumana mwachindunji ndi khungu ndi maso. Pogwiritsa ntchito, magolovesi otetezera oyenera, magalasi ndi zovala zotetezera ziyenera kuvalidwa. Samalani kuti muzisunga pamalo owuma, mpweya wabwino komanso wamdima, kutali ndi zopsereza zoyaka ndi okosijeni.
