3 4-Dibromobenzoic acid (CAS# 619-03-4)

Mawu Oyamba

3,4-Dibromobenzoic acid ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:

Ubwino:

3,4-Dibromobenzoic acid ndi kristalo wopanda mtundu wokhala ndi fungo lapadera lonunkhira. Imakhala yokhazikika pakuwala komanso mpweya, koma imatha kuwola pakatentha kwambiri.

Gwiritsani ntchito:

3,4-Dibromobenzoic asidi angagwiritsidwe ntchito zosiyanasiyana zochita ndi reagents mu kaphatikizidwe organic. Itha kugwiritsidwanso ntchito ngati imodzi mwazinthu zopangira ma organic light-emitting diode (OLEDs).

Njira:

Kukonzekera kwa 3,4-dibromobenzoic acid kungapezeke mwa bromination yankho la bromobenzoic acid. Benzoic acid amayamba kusungunuka mu chosungunulira choyenera ndiyeno bromine amawonjezeredwa pang'onopang'ono. Pambuyo pomaliza, mankhwalawa amatengedwa ndi kusefera ndi crystallization.

Chidziwitso chachitetezo: Ndi chagulu la organic halides ndipo chikhoza kukhala chovulaza anthu komanso chilengedwe. Pewani kukhudzana mwachindunji ndi khungu ndi maso, ndipo onetsetsani kuti mukugwirira ntchito pamalo omwe ali ndi mpweya wabwino wa labotale. Njira zodzitetezera zoyenerera monga magolovesi, magalasi otetezera chitetezo, ndi malaya a labu ziyenera kutengedwa pogwira ntchitoyi. Zinyalala ziyenera kutayidwa moyenera kuti zitsatire malamulo a chilengedwe.
