Intshayelelo
I-2,4-Difluorophenylhydrazine hydrochloride i-organic compound kunye ne-chemical formula C6H6F2N2 · HCl. Oku kulandelayo yinkcazo eneenkcukacha yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:
Indalo:
-Imbonakalo: Ikristale engenambala eqinileyo
-Indawo yokunyibilika: 151-153°C
Ubunzima bemolekyuli obunxulumeneyo: 188.59
-Inyibilikayo: Inyibilika emanzini kunye nezinye izinyibilikisi eziphilayo, njenge-ethanol kunye nechloroform
Sebenzisa:
I-2,4-Difluorophenylhydrazine hydrochloride isetyenziswa kakhulu njenge-agent yokunciphisa kunye ne-nitrogen-containing reagent kwi-organic synthesis. Iyakwazi ukusabela kunye nezinye iikhompawundi eziphilayo ukuvelisa i-hydrazine derivatives, ezifana nokuhlanganiswa kweequinones, okanye ukudibanisa ezinye iikhompawundi ze-nitrogen heterocyclic.
Indlela yokulungiselela:
I-2,4-Difluorophenylhydrazine hydrochloride inokulungiswa ngokuqhelekileyo ngokusabela kwe-phenylhydrazine kunye ne-2,4-difluorobenzaldehyde. Iimeko zokusabela ngokubanzi zibandakanya ukwenza impendulo kwindawo esisiseko kunye nokongezwa kancinci kancinci kwe-hydrochloric acid kunye nemvula elandelayo yemveliso njengetyuwa ye-hydrochloride.
Ulwazi ngoKhuseleko:
- 2,4-Difluorophenylhydrazine hydrochloride yinto enobungozi, nceda uqaphele ukuba ugweme i-inhalation, ukungena okanye ukudibanisa nesikhumba kunye namehlo.
-Nxiba izixhobo ezifanelekileyo zokukhusela ezifana neeglavu, iziphefumli kunye nezibuko ngexesha lokusebenza kunye nokusebenza.
-Nceda uyigcine ivaliwe kwaye ugweme ukunxibelelana nomoya, ukufuma kunye nokukhanya.
-nceda ulandele iinkqubo zokhuseleko lwebhubhoratri, ugweme umlilo kunye nokutshisa kufuphi nokusebenza.
