6-Bromo-2-nitro-pyridin-3-ol (CAS# 443956-08-9)

Mawu Oyamba

Ndi organic pawiri ndi mankhwala chilinganizo C5H3BrN2O3. Zotsatirazi ndizofotokozera za katundu, ntchito, kukonzekera ndi chitetezo cha pawiri:

Chilengedwe:

-Maonekedwe: Crystal ndi ufa wachikasu mpaka lalanje.

-Kusungunuka ndi kuwira: Malo osungunuka a pawiri ndi pafupifupi 141-144 ° C, ndipo kutentha sikudziwika.

-Kusungunuka: Imakhala ndi kusungunuka kochepa m'madzi ndipo imatha kusungunuka muzosungunulira organic monga chloroform, methanol ndi ether.

Gwiritsani ntchito:

- ndi zothandiza ngati wapakatikati mu kaphatikizidwe organic. Itha kugwiritsidwa ntchito ngati zopangira zopangira mankhwala, mankhwala ophera tizilombo ndi mankhwala ena.

Njira Yokonzekera:

- kapena akhoza kukonzekera pochita pyridine ndi asidi bromoacetic, ndiyeno kuchita nitrate anachita pansi zinthu zamchere.

Zambiri Zachitetezo:

-zingakhale zovulaza thanzi mukakumana ndi khungu, maso kapena pokoka mpweya. Kupuma fumbi ndi kukhudzana ndi khungu kuyenera kupewedwa. Valani zida zodzitetezera zoyenera mukamagwiritsa ntchito.

- Pewani kukhudzana ndi ma oxidants amphamvu, ma asidi amphamvu ndi zinthu zina posunga ndikugwira kuti mupewe zoopsa.

-Mukamagwiritsa ntchito ndi kusamalira pawiri, tsatirani njira zolondola za labotale ndi njira zoyendetsera bwino.
