Mawu Oyamba
5-Bromo-2-nitro-benzoic acid ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
- Maonekedwe: 5-Bromo-2-nitro-benzoic acid ndi woyera mpaka kuwala wachikasu crystalline ufa.
- Kusungunuka: Imakhala pafupifupi yosasungunuka m'madzi, koma imasungunuka mu zosungunulira za organic monga ether, methylene chloride, ndi acetone.
Gwiritsani ntchito:
- 5-Bromo-2-nitro-benzoic acid nthawi zambiri amagwiritsidwa ntchito ngati wapakatikati mu kaphatikizidwe ka organic pokonzekera mankhwala ena.
- Itha kugwiritsidwanso ntchito ngati zida zopangira utoto, makamaka kupanga utoto panthawi yopaka utoto.
Njira:
- Kuyambira ndi asidi benzoic, 5-bromo-2-nitro-benzoic asidi akhoza apanga mwa angapo zochita mankhwala. Masitepe apadera amaphatikizapo kusintha kwa mankhwala monga bromination, nitrification, ndi demethylation.
Zambiri Zachitetezo:
- Pali zidziwitso zochepa za kawopsedwe za 5-bromo-2-nitro-benzoic acid, koma zitha kukhala zokwiyitsa komanso zovulaza anthu.
- Njira zoyenera zodzitetezera, monga kuvala magolovesi, magalasi, ndi zovala zodzitchinjiriza, ziyenera kuchitidwa pogwira ndikugwiritsa ntchito mankhwalawa.
- Pewani kukhudzana ndi khungu ndi maso, ndikugwiritsa ntchito pamalo olowera mpweya wabwino.
- Posunga, izi ziyenera kusungidwa mu chidebe chotchinga mpweya, kutali ndi magwero a moto ndi zinthu zomwe zimatha kuyaka.
