Mawu Oyamba
3-Amino-2,6-dichloropyridine ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
3-Amino-2,6-dichloropyridine ndi yolimba yokhala ndi mtundu woyera mpaka wachikasu. Sipasungunuke m'madzi kutentha kwa firiji koma imatha kusungunuka muzinthu zina zosungunulira monga ethanol ndi ethers. Ili ndi kusakhazikika kwina.
Gwiritsani ntchito:
3-Amino-2,6-dichloropyridine ndi yofunika kwambiri pakati pa kaphatikizidwe ka organic. Itha kugwiritsidwanso ntchito ngati mankhwala aulimi monga mankhwala ophera tizilombo, herbicides, ndi mankhwala a rhizome.
Njira:
Njira imodzi yokonzekera 3-amino-2,6-dichloropyridine imapezeka pochita 2,6-dichloropyridine ndi ammonia. Zimene angathe kuchitidwa pamaso pa m'malo reagents kapena catalysts.
Zambiri Zachitetezo:
3-Amino-2,6-dichloropyridine imakwiyitsa komanso yovulaza. Zida zodzitetezera zoyenerera monga magolovesi ndi magalasi ziyenera kuvalidwa pogwira. Pewani kukhudza khungu, maso, ndi kupuma. Mukamagwiritsa ntchito kapena kusungirako, chidwi chiyenera kulipidwa pakupewa moto ndikupewa kukhudzana ndi okosijeni. Mukalowetsedwa kapena kupumira, pitani kuchipatala mwamsanga.
