Intshayelelo
I-3,5-difluorophenylhydrazine hydrochloride yi-organic compound. Oku kulandelayo kukwazisa ngobume bayo, ukusetyenziswa, indlela yokuvelisa kunye nolwazi lokhuseleko:
Iipropati: Iyanyibilika emanzini kunye nezinye izinyibilikisi eziphilayo ezifana ne-ethanol, i-methanol. Yinto eneasidi ebuthathaka edibana neealkali.
Sebenzisa:
I-3,5-difluorophenylhydrazine hydrochloride isetyenziswa rhoqo njenge-arhente yokunciphisa kunye ne-activator kwi-organic synthesis. Ingasetyenziselwa ukusabela okongeziweyo, ukunciphisa iikhompawundi eziphilayo ezifana neeketoni, iialdehydes, iiketoni ezinuka kamnandi, njl.
Indlela:
I-3,5-Difluorophenylhydrazine hydrochloride inokufumaneka ngokusabela kwe-hydroquinone kunye ne-2-chloro-1,3,5-trifluorobenzene. Ngokubanzi, i-hydroquinone iphendula ngokugqithisileyo kwe-2-chloro-1,3,5-trifluorobenzene phantsi kweemeko ze-alkaline ukufumana i-3,5-difluorophenylhydrazine. Ngokuyiphendula nge-hydrogen chloride, i-3,5-difluorophenylhydrazine hydrochloride inokufumaneka.
Ulwazi ngoKhuseleko:
I-3,5-Difluorophenylhydrazine hydrochloride yikhemikhali esetyenziswa ngokubanzi kwiibhubhoratri kunye nokuveliswa kwemveliso. Imithetho efanelekileyo ifanele ilandelwe ngexesha lenkqubo, yaye kufuneka kunxitywe izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu, iiglasi zokhuseleko kunye needyasi zaselabhu. Ayinatyhefu encinci, kodwa kufuneka ithintelwe ekudibaneni nolusu, amehlo, kunye nokuphefumla. Kwimeko yokuvezwa, kuyimfuneko ukuhlamba ngokukhawuleza ngamanzi amaninzi kwaye ufune unyango ngokukhawuleza. Ngexesha lokugcinwa, kufuneka kugcinwe kude nemithombo yomlilo kunye nezinto ezinokutsha, kwaye zigcinwe kwindawo eyomileyo, enomoya.
