Mawu Oyamba
2-Hydroxy-3-nitrobenzaldehyde ndi organic compound yomwe imadziwikanso kuti 3-nitro-2-hydroxybenzaldehyde. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
- Maonekedwe: Mtundu wachikasu wa crystalline.
Gwiritsani ntchito:
- Itha kugwiritsidwa ntchito ngati poyambira pakupanga zinthu zina zakuthupi, monga maantibayotiki opangira ndi utoto.
Njira:
- Kukonzekera kwa 2-hydroxy-3-nitrobenzaldehyde kumatha kupezedwa ndi nitrification wa parabentaldehyde.
- Kawirikawiri pamaso pa nitrifying agent, benzaldehyde pang'onopang'ono amasakanikirana ndi nitric acid, ndipo mankhwala omwe amapezeka pambuyo pake ndi 2-hydroxy-3-nitrobenzaldehyde.
- Njira yophatikizira iyenera kuchitidwa pansi pamiyeso yoyenera kuti iwonetsetse chitetezo ndi zokolola zambiri.
Zambiri Zachitetezo:
- 2-Hydroxy-3-nitrobenzaldehyde ndi mankhwala oopsa omwe amatha kuyaka.
- Tsatirani machitidwe achitetezo a labotale yamankhwala ndikuvala magolovesi oteteza, magalasi, ndi malaya a labotale oyenera mukamagwira ntchito.
- Pewani kukhudza khungu, maso, ndi zovala, ndipo samalani kuti musapumedwe ndi ufa kapena mpweya wake.
