Mawu Oyamba
3-bromo-4-methoxypyridine ndi mankhwala opangidwa ndi mankhwala a C6H6BrNO ndi kulemera kwa molekyulu ya 188.03. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
1. Maonekedwe: 3-bromo-4-methoxypyridine ndi yopepuka yachikasu mpaka yolimba yachikasu.
2. solubility: sungunuka mu zosungunulira organic monga etha ndi chlorinated hydrocarbons, osasungunuka m'madzi.
3. Malo osungunuka: pafupifupi 50-53 ℃.
4. kachulukidwe: pafupifupi 1.54 g/cm.
Gwiritsani ntchito:
3-bromo-4-methoxypyridine ndi yofunika organic synthesis wapakatikati, ambiri ntchito synthesis wa mankhwala, mankhwala ndi zina organic mankhwala. Lili ndi ntchito zambiri m'munda wa kafukufuku wamankhwala ndi mankhwala.
Njira Yokonzekera:
3-bromo-4-methoxypyridine nthawi zambiri amapangidwa ndi izi:
1. 2-bromo-5-nitropyridine imakhudzidwa ndi methanol kuti ipeze 2-methoxy-5-nitropyridine.
2. 2-methoxy-5-nitropyridine imakhudzidwa ndi cuprous bromide yokonzedwa ndi sulfuric acid kuti ipeze 3-bromo-4-methoxypyridine.
Zambiri Zachitetezo:
1. 3-bromo-4-methoxypyridine imakwiyitsa ndipo sayenera kukhudzana ndi khungu, maso ndi kupuma.
2. Pogwira ndi kugwiritsa ntchito, ayenera kuvala zida zodzitetezera zoyenera, monga magolovesi ndi magalasi odzitetezera.
3. Kusungirako kuyenera kupewa kukhudzana ndi okosijeni ndi ma asidi amphamvu, ndikusunga chidebe chosindikizidwa.
4. Pogwiritsa ntchito bwino komanso kusunga zinthu, 3-bromo-4-methoxypyridine ndi mankhwala otetezeka, koma amafunikabe kugwiritsidwa ntchito mosamala.
