Mawu Oyamba
3-choro-5-(trifluoromethyl)pyridine ndi organic compound yokhala ndi mankhwala C≡H₂ ClFΛ N. Ndi madzi achikasu otuwa komanso onunkhira kwambiri. Zotsatirazi ndizofotokozera za chikhalidwe, kagwiritsidwe ntchito, kukonzekera ndi chitetezo cha 3-choro-5-(trifluoromethyl)pyridine:
Chilengedwe:
-Kuchulukana: 1.578 g/mL
- Malo otentha: 79-82 ℃
-Posungunuka: -52.5 ℃
-Kusungunuka: Kusungunuka mu zosungunulira organic monga ethanol, etha ndi dichloromethane, sungunuka pang'ono m'madzi.
Gwiritsani ntchito:
- Monga reagents ndi intermediates mu kaphatikizidwe organic, ntchito synthesis wa mankhwala, mankhwala ndi zina organic mankhwala.
-Kufufuza pazamankhwala, monga kaphatikizidwe ka mankhwala odana ndi khansa ndi zolembera.
Njira Yokonzekera:
3-chloro-5-(trifluoromethyl)pyridine ikhoza kukonzedwa ndi njira ziwiri izi:
1. Kugwiritsa ntchito pyridine monga zopangira, chlorination reaction ikuchitika pamaso pa hydrochloric acid, ndiyeno trifluoromethylation anachita pamaso pa sodium trifluoromethylate.
2. Pogwiritsa ntchito 3-picolinic acid monga zopangira, chlorination reaction ikuchitika pamaso pa thionyl chloride, ndiyeno trifluoromethylation reaction ikuchitika pamaso pa trifluoromethyl mercaptan.
Zambiri Zachitetezo:
- 3-chloro-5-(trifluoromethyl)pyridine imakwiyitsa ndipo imatha kuyambitsa kuyabwa pokhudzana ndi khungu ndi maso. Ndikofunikira kuvala zodzitetezera zoyenera mukamagwiritsa ntchito, monga kuvala magalasi oteteza, magolovesi ndi zovala zodzitetezera.
-Pewani kutulutsa mpweya wake ndikuwonetsetsa kuti ntchitoyo ikuchitika pamalo abwino mpweya wabwino.
-Posunga, sungani mu chidebe chotsekedwa, kutali ndi moto ndi oxidizing agents.
-Potaya zinyalala, zisamalireni ndikuzitaya motsatira malamulo a mderalo.
-Chonde onani Tsamba Loyenera la Chitetezo (SDS) kuti mudziwe zambiri zachitetezo.
