Mawu Oyamba
4-Chloro-2-bromobenzoic acid amadziwikanso kuti 4-chloro-2-bromobenzoic acid. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, njira zopangira ndi chitetezo:
Ubwino:
4-Chloro-2-bromo-benzoic acid ndi cholimba cha crystalline choyera. Ili ndi kusungunuka kochepa ndipo imakhala yosasungunuka m'madzi, koma imasungunuka mu zosungunulira za organic.
Gwiritsani ntchito:
Pawiri izi nthawi zambiri ntchito ngati wapakatikati mu organic synthesis zimachitikira. 4-Chloro-2-bromo-benzoic acid itha kugwiritsidwanso ntchito ngati dispersant utoto pamakampani opanga utoto.
Njira:
Njira yomwe imagwiritsidwa ntchito popangira 4-chloro-2-bromo-benzoic acid ndikuchita 2-bromo-4-nitrobenzoic acid ndi nitrous acid kuti ipeze 2-bromo-4-nitrophenol, ndiyeno mankhwala omwe akuwafuna amalandira ndi anachita ndi mankhwala.
Zambiri Zachitetezo:
4-Chloro-2-bromo-benzoic acid nthawi zambiri amawonedwa kuti ali ndi kawopsedwe kakang'ono pakagwiritsidwe ntchito bwino komanso kasungidwe. Zikhoza kukhala ndi zotsatira zokhumudwitsa m'maso, pakhungu, ndi m'mapapu. Kukhudzana mwachindunji ndi khungu ndi maso kuyenera kupewedwa mukamagwiritsa ntchito, komanso mpweya wabwino uyenera kusamalidwa. Pogwira kapena kusungunula, njira zoyenera zodzitetezera monga maso ndi manja ziyenera kuchitidwa. Ngati mankhwalawa akukokedwa kapena kulowetsedwa, pitani kuchipatala mwamsanga.
