Mawu Oyamba
2,5-Dibromo-3-nitropyridine (2,5-dibromo-3-nitropyridine) ndi organic pawiri. Zina mwazinthu, ntchito, kukonzekera ndi chitetezo cha 2,5-dibromo-3-nitropyridine zaperekedwa pansipa:
Katundu:
- Maonekedwe : 2,5-Dibromo-3-nitropyridine ndi yolimba yachikasu.
- Solubility : 2,5-Dibromo-3-nitropyridine imasungunuka mu zosungunulira za organic monga ethanol, dimethyl sulfoxide ndi dichloromethane komanso osasungunuka m'madzi.
Zogwiritsa:
- 2,5-Dibromo-3-nitropyridine ntchito ngati wapakatikati mu kaphatikizidwe organic.
- Amagwiritsidwanso ntchito pokonzekera mankhwala a nayitrogeni okhala ndi heterocyclic, monga zotumphukira za pyridine.
Njira Yokonzekera:
- Kukonzekera 2,5-dibromo-3-nitropyridine zambiri ikuchitika ndi kupanga zimachitikira. Njira yodziwika bwino yopangira ndikupeza chinthu chomwe mukufuna kuchokera ku pyridine ngati poyambira ndi bromination ndi nitration. Njira zenizeni zopangira zitha kusinthidwa momwe zingafunikire.
Zambiri Zachitetezo:
- 2,5-Dibromo-3-nitropyridine sichimaika chiopsezo chachikulu chachitetezo pakagwiritsidwe ntchito.
- Komabe, monga mankhwala, njira zodzitetezera za labotale ziyenera kutsatiridwa. Kukhudzana ndi khungu, maso ndi mucous nembanemba ziyenera kupewedwa. Njira zodzitetezera monga magolovesi, magalasi ndi malaya a labotale ziyenera kuwonedwa mukamagwira.
- Mukalowetsedwa mwangozi kapena kupumira pawiri, pitani kuchipatala msanga. Mukakhudza khungu kapena maso, yambani mwamsanga ndi madzi ambiri ndikupempha thandizo lachipatala.
