Intshayelelo
I-4-Ethylpyridine i-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-4-ethylpyridine:
Umgangatho:
-Imbonakalo: Ulwelo olungenambala okanye oluqinileyo lwekristale.
- Ukunyibilika: Inyibilika kuninzi lwezinyibilikisi zendalo, ezinganyibilikiyo emanzini.
Sebenzisa:
- Njenge-solvent: I-4-ethylpyridine ine-solubility efanelekileyo kwaye isoloko isetyenziswa njenge-solvent okanye i-reaction medium, ngokukodwa kwi-organic synthesis, enokukhuthaza inkqubela phambili yokuphendula.
- I-Catalyst: I-4-ethylpyridine ingasetyenziselwa njenge-catalyst ye-organic reactions, njenge-Grignard reagent reactions kunye ne-hydrogenation reactions.
Indlela:
- I-4-Ethylpyridine inokulungiswa ngokuphendula kwe-2-ethylpyridine kunye ne-ethyl acetate, ngokuqhelekileyo phantsi kweemeko ze-alkaline.
Ulwazi ngoKhuseleko:
- I-4-Ethylpyridine iyacaphukisa kwaye inokubangela ukucaphuka kwamehlo, ulusu, kunye nendlela yokuphefumla. Nxiba izixhobo ezifanelekileyo zokukhusela ngexesha lokuphatha kwaye ugweme ukudibana ngokuthe ngqo nolusu, amehlo, okanye iigesi eziphefumlayo.
- Xa usebenzisa okanye ugcina, gcina i-4-ethylpyridine kude namaqondo obushushu aphezulu kunye namadangatye avulekileyo.
- Xa ulahla inkunkuma, kuyimfuneko ukuyilahla ngokuhambelana nemithetho yendawo kunye nemimiselo yokuphepha ukungcola kokusingqongileyo.
