Isingeniso
I-2,4-Difluorophenylhydrazine hydrochloride iyinhlanganisela ye-organic enefomula yamakhemikhali C6H6F2N2 · HCl. Okulandelayo incazelo eningiliziwe yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: I-crystalline engenambala eqinile
-Indawo yokuncibilika: 151-153°C
- Isisindo samangqamuzana esihlobene: 188.59
-Incibilika: Incibilika emanzini nakwezinye izincibilikisi eziphilayo, njenge-ethanol ne-chloroform
Sebenzisa:
I-2,4-Difluorophenylhydrazine hydrochloride isetshenziswa ngokuyinhloko njenge-ejenti yokunciphisa kanye ne-reagent ene-nitrogen ku-organic synthesis. Ingasabela ngezinye izinhlanganisela eziphilayo ukuze ikhiqize okuphuma kokunye kwe-hydrazine, njengokuhlanganiswa kwamaquinone, noma ukuhlanganiswa kwezinye izinhlanganisela ze-nitrogen heterocyclic.
Indlela Yokulungiselela:
I-2,4-Difluorophenylhydrazine hydrochloride ngokuvamile ingalungiswa ngokusabela kwe-phenylhydrazine kanye ne-2,4-difluorobenzaldehyde. Izimo zokusabela ngokuvamile zihlanganisa ukwenza ukusabela ngendlela eyisisekelo kanye nokwengezwa kancane kancane kwe-hydrochloric acid kanye nemvula elandelayo yomkhiqizo njengosawoti we-hydrochloride.
Ulwazi Lokuphepha:
I-2,4-Difluorophenylhydrazine hydrochloride iyinto eyingozi, sicela uqaphele ukugwema ukuhogela, ukukungenisa noma ukuthinta isikhumba namehlo.
-Gqoka izinto zokuzivikela ezifanele njengamagilavu, ama-respirators kanye nezibuko ngesikhathi sokusebenzisa nokusebenza.
-Sicela uyigcine ivaliwe futhi ugweme ukuthintana nomoya, umswakama nokukhanya.
-sicela ulandele izinqubo zokuphepha zaselabhorethri, ugweme umlilo nokushisa eduze nokusebenza.
