Mawu Oyamba
2,5-Dibromo-3-trimethylpyridine ndi organic pawiri. Zotsatirazi ndikuyambitsa zina mwazinthu zake, ntchito, njira zopangira ndi chidziwitso chachitetezo:
Ubwino:
- Maonekedwe: 2,5-Dibromo-3-trimethylpyridine ndi madzi achikasu otumbululuka.
- Kusungunuka: Kutha kusungunuka mu zosungunulira zambiri za organic, monga ethanol, acetone, ndi dimethyl sulfoxide.
- Kukhazikika: Ndiwokhazikika pakuwala komanso kutentha, koma kuwola kumatha kuchitika pansi pamikhalidwe yamphamvu yamchere.
Gwiritsani ntchito:
- Monga chothandizira: 2,5-dibromo-3-trimethylpyridine angagwiritsidwe ntchito ngati brominating agent kuti catalyze zochita zina organic, monga nucleophilic m'malo, makutidwe ndi okosijeni, ndi condensation.
- Organic synthesis: Itha kugwiritsidwa ntchito ngati yapakatikati pakuphatikizika kwazinthu zachilengedwe, makamaka pamagulu okhala ndi ketone kapena magulu a aldehyde.
- Utoto wa Photosensitive: Itha kugwiritsidwanso ntchito popanga utoto wowoneka bwino.
Njira:
Kawirikawiri, 2,5-dibromo-3-trimethylpyridine ikhoza kukonzedwa ndi bromination reaction ndi bromine monga reactant mu machitidwe a trimethylpyridine. Zomwe zimachitika zimatha kutsimikiziridwa pazochitika ndizochitika, koma chisamaliro chiyenera kutengedwa kuti chigwire ntchito motetezeka.
Zambiri Zachitetezo:
- 2,5-Dibromo-3-trimethylpyridine imawononga khungu ndi maso ndipo iyenera kupewedwa pokhudzana mwachindunji.
- Valani zovala zoteteza maso, magolovesi ndi zovala zodzitchinjiriza mukamagwiritsa ntchito.
- Gwirani ntchito pamalo olowera mpweya wabwino ndikupewa kutulutsa nthunzi wake.
- Pewani kukhudzana ndi oxidizing amphamvu, zomwe zingayambitse zoopsa.
- Zinyalala ziyenera kutayidwa motsatira malamulo a m'deralo.
