Intshayelelo
I-3-(trifluoromethyl) pyridine, eyaziwa ngokuba yi-1-(trifluoromethyl) pyridine, i-organic compound.
Umgangatho:
3-(trifluoromethyl)pyridine lulwelo olungenambala nevumba elinamandla. Inyibilika kwiintlobo ezininzi ze-organic solvents ezifana ne-ethanol, i-dimethylformamide, kunye ne-dimethyl sulfoxide.
Sebenzisa:
I-3-(trifluoromethyl) i-pyridine isetyenziswa ngokubanzi njenge-catalysts, i-solvents kunye ne-reagents kwi-organic synthesis. Ingasetyenziswa njenge-boron chloride reagent kwi-synthesis ye-alcohol, i-acids, kunye ne-ester derivatives. Inokusetyenziswa kwakhona njenge-sodium hydroxide-catalyzed borate esterification reagent ye-aldehydes kunye ne-ketones.
Indlela:
Kukho iindlela ezininzi zokulungisa i-3-(trifluoromethyl)pyridine. Indlela eqhelekileyo kukufumana imveliso ngokusabela kwepyridine kunye ne-trifluoromethylsulfonyl fluoride. Ipyridine yanyibilika kwisinyibiliki se-ether, emva koko i-trifluoromethylsulfonyl fluoride yongezwa kancinci kancinci. Iimpendulo zidla ngokuqhutywa kumaqondo obushushu aphantsi kwaye zifuna umoya owaneleyo ukuthintela ukwanda kweegesi eziyityhefu.
Ulwazi ngoKhuseleko: Lulwelo olunokutsha olunokwenza lula umlilo xa lubekwe kwidangatye elivulekileyo okanye kubushushu obuphezulu. Ikwasisinyibilikisi esiphilayo esinokuba nefuthe elicaphukisayo eluswini, emehlweni, nakwinkqubo yokuphefumla. Iiglavu ezikhuselayo, iiglavu kunye nezixhobo zokuphefumla zifanele zinxitywe ngexesha lokusebenza, kwaye utyando kufuneka lwenziwe kwindawo engena umoya.
