Mawu Oyamba
5-Bromo-2-methylpyridine ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha pawiri:
Ubwino:
Maonekedwe: 5-bromo-2-methylpyridine ndi kristalo wopanda mtundu kapena wotumbululuka wachikasu.
Kusungunuka: Kutha kusungunuka mu zosungunulira zambiri za organic ndipo kumakhala ndi kusungunuka kochepa m'madzi.
Gwiritsani ntchito:
Catalyst: Itha kugwiritsidwanso ntchito ngati chothandizira pazochitika zinazake.
Njira:
Njira yodziwika bwino yopangira 5-bromo-2-methylpyridine ndi brominated 2-methylpyridine. Njira zenizeni ndi izi:
2-methylpyridine imasungunuka mu zosungunulira.
Brominating agent, monga madzi a bromine kapena mercuric chloride, amawonjezeredwa ku yankho kuti apange 5-bromo-2-methylpyridine.
Sefa ndi kristalo kuti mupeze chinthu choyera.
Zambiri Zachitetezo:
5-Bromo-2-methylpyridine ndi gulu la organobromine ndipo liyenera kusamaliridwa mosamala kuti lipewe kukhudzana ndi khungu, maso ndi kupuma.
Pewani kutulutsa ufa wake kapena utsi umene umatulutsa.
Magolovesi otetezera oyenerera, magalasi otetezera chitetezo ndi masks otetezera ayenera kuvala panthawi yogwira ntchito.
Mukamagwiritsa ntchito kapena kusunga, ziyenera kusungidwa kutali ndi kuyatsa ndi okosijeni.
Pogwira 5-bromo-2-methylpyridine, njira zogwirira ntchito zotetezeka ziyenera kutsatiridwa ndikusamalidwa pamalo abwino.
