Isingeniso
I-3,4-Difluorophenylhydrazine hydrochloride iyinhlanganisela yezinto eziphilayo.
Kuyinhlanganisela encibilika kalula emanzini nasezincibilikisini eziningi eziphilayo.
Ukusetshenziswa: I-3,4-difluorophenylhydrazine hydrochloride ivame ukusetshenziswa njenge-intermediate and catalyst in organic synthesis. Ingasetshenziswa ekuphenduleni kwe-fluorination, ukusabela kokunciphisa, nokuguqulwa kwezinhlanganisela ze-carbonyl zibe amaqembu athile e-methylene ku-organic synthesis. Ingasetshenziswa futhi ukuvimbela ukugqwala kwensimbi.
Indlela yokulungiselela: I-3,4-difluorophenylhydrazine hydrochloride ingatholakala ngokusabela kwe-phenylhydrazine ne-hydrogen chloride. Ukusabela kuvame ukwenzeka ekamelweni lokushisa lapho i-phenylhydrazine imisiwe ku-ethanol egcwele kulandelwa ukufakwa kancane kwegesi ye-hydrogen chloride.
Ulwazi lokuphepha: I-3,4-difluorophenylhydrazine hydrochloride inobuthi obuphansi, kodwa ukuphathwa okuphephile kusadingeka. Ngesikhathi sokusebenza, gwema ukuhogela uthuli, gwema ukuthinta isikhumba, futhi ugcine izimo ezinhle zokungenisa umoya. Izimpahla zokuzivikela ezifanele njengamagilavu amakhemikhali kanye nezibuko zokuphepha kufanele zigqokwe ngesikhathi sokuphatha.
