Intshayelelo
I-3-Chloro-2-hydroxy-5-(trifluoromethyl) pyridine yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, iindlela zokwenza kunye nolwazi lokhuseleko:
1. Indalo:
- Imbonakalo: 3-Chloro-2-hydroxy-5-(trifluoromethyl)pyridine yinto eqinileyo engenambala ukuya kumthubi.
- Ukunyibilika: Kuphantse kwanganyibiliki emanzini, kodwa kunyibilika kwizinyibilikisi eziphilayo ezifana ne-ether, i-methanol kunye ne-methylene chloride.
- Iipropati zeMichiza: Yikhompawundi ye-alkaline eyenza i-neutraizing reaction against acids. Isenokusetyenziswa njenge-reagent fluorinating ukwazisa amaqela e-trifluoromethyl kwezinye iikhompawundi eziphilayo.
2. Ukusetyenziswa:
- I-3-Chloro-2-hydroxy-5- (trifluoromethyl) i-pyridine isetyenziswa ngokuqhelekileyo kwiimpendulo ze-organic synthesis njenge-catalyst okanye i-reagent. Ngokomzekelo, ingasetyenziselwa ukwakha iibhondi ze-carbon-fluorine kunye neempendulo ze-amination.
- Isenokusetyenziswa njengesixhobo sokuqala okanye esiphakathi ekudibaneni kwezitshabalalisi.
3. Indlela:
- Indlela esetyenziswa ngokuqhelekileyo yokulungisa i-pyridine kunye ne-trifluoroformic acid kunye ne-sulfuric acid ukuvelisa i-3-chloro-2-hydroxy-5- (trifluoromethyl) pyridine.
4. Ulwazi ngoKhuseleko:
- I-3-Chloro-2-hydroxy-5-(trifluoromethyl) pyridine kufuneka igwenywe ngexesha lokugcina kwaye isetyenziswe ngokudibana nee-oxidants ezinamandla kunye nezinto ezinokutsha ukuphepha umlilo okanye ukuqhuma.
- Inokuba nefuthe elicaphukisayo eluswini, emehlweni, nakwindlela yokuphefumla, kunye nezixhobo ezifanelekileyo zokukhusela ezinjengeeglavu, izibuko, kunye nezixhobo zokukhusela ukuphefumla kufuneka zinxitywe xa usebenza.
- Xa usebenzisa okanye uphatha i-compound, kufuneka yenziwe kwindawo enomoya kwaye ugweme ukuphefumla okanye ukungena ngengozi. Emva kokunyanga, indawo engcolileyo kufuneka ihlambuluke ngokucokisekileyo.
