Intshayelelo
I-organic compound kunye ne-chemical formula C6H7FN2. Oku kulandelayo sisingeniso kwezinye iimpawu zayo, ukusetyenziswa, iindlela kunye nolwazi lokhuseleko:
Indalo:
1. Imbonakalo: Ayinabala ukuya koluthubi yikristale eqinileyo.
2. Indawo enyibilikayo: malunga ne-82-85 ℃.
3. Indawo yokubila: Malunga ne-219-221 ℃.
4. Ukunyibilika: Inyibilika kuninzi lwezinyibilikisi ze-organic ezifana ne-ethanol, i-ether kunye ne-dichloromethane.
Sebenzisa:
Isetyenziswa ikakhulu njengendawo ephakathi kwi-organic synthesis. Ingasetyenziselwa ukulungiselela iintlobo ezahlukeneyo zezinto eziphilayo, ezifana neziyobisi, izibulala-zinambuzane, idayi kunye ne-ligands. Kananjalo inexabiso elinokubakho lesicelo kwintsimi yeyeza.
Indlela:
ngokuqhelekileyo ifunyenwe ngokuphendula i-pyridine nge-reagent fluorinating kunye ne-amino reagent ye-methylation reaction. Indlela ethile yokudibanisa ingahlengahlengiswa kwaye iphuculwe ngokweemfuno zokwenyani.
Ulwazi ngoKhuseleko:
1. Isenokucaphukisa amehlo, ulusu kunye nenkqubo yokuphefumla. Sebenzisa kufuneka uqaphele ukuphepha ukudibanisa.
2. Nxiba izixhobo ezifanelekileyo zokukhusela ezifana neeglavu, iiglasi zokhuseleko kunye neemaski zokukhusela ngexesha lokusebenza.
3. Kuphephe ukuphefumla uthuli, umsi neegesi. Indawo yokusebenzela kufuneka ingene umoya.
4. Ukuba ukudibana ngengozi okanye ukusetyenziswa kakubi, kufuneka uhlambe ngokukhawuleza okanye unyango lwezonyango.
