Mawu Oyamba
4-Bromo-2-nitrobenzoic acid ndi organic pawiri, nthawi zambiri amafupikitsidwa monga BNBA. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:
Ubwino:
- Maonekedwe: 4-Bromo-2-nitrobenzoic asidi ndi woyera crystalline olimba.
- Kusungunuka: Kutha kusungunuka muzosungunulira wamba monga ethanol, chloroform ndi dimethylformamide.
Gwiritsani ntchito:
- Munda wa pigment: Chigawochi chitha kugwiritsidwa ntchito popanga utoto wapadera.
Njira:
- Kukonzekera kwa 4-bromo-2-nitrobenzoic acid nthawi zambiri kumachitika pochita 2-nitrobenzoic acid ndi bromine pansi pa acidic. Kuti mudziwe njira yokonzekera, chonde onani zolemba za organic synthesis.
Zambiri Zachitetezo:
- Pawiriyi imakhala ndi mkwiyo wina, ndipo njira zodzitetezera monga kuvala magolovesi, magalasi, ndi zina zotero, ziyenera kutengedwa panthawi yogwira ntchito.
- Khalani kutali ndi moto wosatseguka ndi zinthu zotentha kwambiri, ndipo sungani pamalo ozizira, owuma.
- Palibe chidziwitso chokwanira cha kawopsedwe, kawopsedwe ka 4-bromo-2-nitrobenzoic acid sichidziwika, ndipo kusamala kuyenera kuchitidwa poigwiritsa ntchito kapena kuigwira, ndipo njira zoyenera zogwirira ntchito ziyenera kutsatiridwa.
