Intshayelelo
I-2,5-Difluorobenzonitrile yi-organic compound. Oku kulandelayo sintshayelelo kwezinye iipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-2,5-difluorobenzonitrile:
Umgangatho:
- 2,5-Difluorobenzonitrile yikristale engenambala ukuya kumthubi nevumba elibi.
- I-2,5-difluorobenzonitrile iphantse ingabikho emanzini kwiqondo lokushisa, kodwa i-soluble kwii-solvents eziphilayo ezifana ne-ethanol, i-acetone, njl.
- Yikhompawundi enevumba elimnandi elimnandi.
Sebenzisa:
- I-2,5-Difluorobenzonitrile isetyenziswa ngokubanzi kwi-organic synthesis njenge-reagent yekhemikhali yokulungiswa kwamanye ama-organic compounds.
- Isetyenziswa ngokuqhelekileyo kwi-fluorination reactions kunye ne-aromatization reactions ngenxa yokuba ukuqaliswa kwee-athomu ze-fluorine kunokutshintsha iimpawu ze-compounds, ukwandisa i-hydrophobicity kunye nokuzinza kweekhemikhali.
Indlela:
- I-2,5-difluorobenzonitrile ingalungiswa nge-aromatics substitution reaction. Indlela eqhelekileyo yokulungiswa kukusabela kwi-para-dinitrobenzene kunye ne-nitrosamines catalyzed yi-cuprous chloride kunye ne-hydrofluoric acid ukufumana i-2,5-difluorobenzonitrile.
Ulwazi ngoKhuseleko:
- Xa uphethe i-2,5-difluorobenzonitrile, nxiba izixhobo ezifanelekileyo zokukhusela ezinjengeeglavu zokukhusela iikhemikhali, iiglavu, kunye nedyasi yelebhu.
- Yikhompawundi ecaphukisayo enokubangela ukucaphuka kwamehlo, ulusu, kunye nendlela yokuphefumla.
- Ukuphefumlela umphunga okanye uthuli, ulusu kunye nokudibana kwamehlo kufuneka kugwenywe ngexesha lokuphatha.
- Ingqalelo kufuneka ihlawulwe kumanyathelo okuthintela umlilo kunye nokudubula ngexesha lokugcinwa kunye nokusetyenziswa, kwaye ugcine kude nemithombo yomlilo kunye nee-oxidants.
