Intshayelelo
Yikhompawundi ephilayo. Ifomula yayo yeekhemikhali yi-C6H6BrFN kwaye ubunzima bayo be-molecular yi-188.03g / mol.
Ikhompawundi lulwelo olungenambala ukuya kumthubi oluluthuthu olunevumba elinukayo. Ineqondo lokunyibilika elingu -2°C kunye neqondo lokubila lika 80-82°C. Inokuchithwa kwii-solvents eziphilayo ezifana ne-ethanol kunye ne-dimethylformamide kwiqondo lokushisa eliqhelekileyo.
Ingasetyenziswa njengendawo ephakathi kwi-organic synthesis kwaye isetyenziswa ngokubanzi kwimimandla ye-pesticide, amayeza kunye nesayensi yezinto. Ingasetyenziselwa ukuhlanganiswa kwamanye ama-acidic compounds, i-glyphosate synthesis, i-microscopy kunye ne-labeling fluorescent, njl.
Iphosphor inokulungiswa ngokuzisa i-bromine kunye ne-athomu ye-fluorine kwi-picoline. Enye indlela eqhelekileyo kukusebenzisa i-bromine kunye negesi ye-fluorine ukusabela nge-2-methylpyridine. Ukusabela kufuneka kuqhutywe kwi-solvent efanelekileyo yokusabela kwaye idinga ukufudumeza kunye nokuzamisa.
Ngokuphathelele ulwazi lokhuseleko, gcina kude nomlilo kunye nobushushu obuphezulu. Sebenzisa ngeeglavu ezifanelekileyo zokukhusela kunye nokukhuselwa kwamehlo. Xa udibana nesikhumba okanye amehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune uncedo lwezonyango. Imimiselo efanelekileyo yokhuseleko lweekhemikhali kufuneka igcinwe ngexesha lokugcinwa kunye nokuphatha.
