Mawu Oyamba
2-Fluoro-4-bromobenzyl bromide ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
- Maonekedwe: 2-Fluoro-4-bromobenzyl bromide ndi madzi achikasu otuwa.
- Kusungunuka: Imasungunuka mu zosungunulira za organic monga ma alcohols ndi ether, koma osasungunuka m'madzi.
Gwiritsani ntchito:
- 2-Fluoro-4-bromobenzyl bromide nthawi zambiri amagwiritsidwa ntchito ngati gawo lapakati pakupanga organic.
- Pagululi litha kugwiritsidwanso ntchito ngati zopangira zopangira zopangira ndi zopangira ma surfactants.
Njira:
Njira yokonzekera 2-fluoro-4-bromobenzyl bromide ndi motere:
- Kuchita kwa 2-bromobenzyl mowa wokhala ndi 2,4-difluorobenzoic acid, wopangidwa ndi alkali, pa kutentha koyenera komanso nthawi.
- Pambuyo pomaliza, kuyeretsedwa ndi kupatukana kumachitika ndi crystallization kapena distillation kuti mupeze 2-fluoro-4-bromobenzyl bromide ndi chiyero chachikulu.
Zambiri Zachitetezo:
- 2-Fluoro-4-bromobenzyl bromide ndi organic pawiri ndipo nthunzi yake iyenera kupewedwa pokoka mpweya.
- Valani zida zodzitetezera zoyenera monga magalasi odzitetezera, magolovesi ndi malaya a labu pamene mukugwira ndikugwira.
- Posunga ndi kugwiritsa ntchito, pewani kukhudzana ndi ma okosijeni, ma asidi amphamvu, ma alkali amphamvu ndi zinthu zina kuti mupewe zoopsa.
- Posunga ndi kutaya, malamulo oyenera, malamulo ndi chitetezo ziyenera kutsatiridwa.
