Intshayelelo
I-3,5-difluorobenzaldehyde yi-organic compound kunye ne-chemical formula C7H4F2O. Oku kulandelayo yinkcazo yeepropati, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko lwekhompawundi:
Iipropati: I-3,5-difluorobenzaldehyde yinto eqinileyo engenambala ukuya ekukhanyeni emthubi kunye nevumba elikhethekileyo lephenone. Inoxinano lwe 1.383g/cm³, indawo yokunyibilika eyi 48-52°C, kunye neqondo lokubila lika 176-177°C. I-3,5-difluorobenzaldehyde ayinyibiliki emanzini, kodwa inyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol, i-ether, kunye ne-benzene.
Ukusetyenziswa: I-3,5-difluorobenzaldehyde isetyenziswa ngokuqhelekileyo njengendawo ephakathi kwi-organic synthesis. Ingasetyenziselwa ukudibanisa iikhompawundi ezahlukeneyo ezine-fluorine, ngakumbi ukwenzeka kweekhemikhali ezizisa iiathom zefluorine kwiiathom zendalo. Ukongeza, inokusetyenziswa njengento ephakathi yokwenziwa kweziyobisi, izitshabalalisi kunye nedayi.
indlela yokulungiselela: indlela yokulungiselela i-3,5-difluorobenzaldehyde inokufumaneka ngokuphendula i-3,5-difluorobenzyl methanol kunye ne-asidi aldehyde reagent (njenge-trichloroformic acid, njl.). Iindlela ezithile zokwenziwa zingabhekisa kwi-Organic Synthesis Handbook kunye noncwadi olunxulumeneyo.
Ulwazi lokhuseleko: I-3,5-difluorobenzaldehyde yikhemikhali kwaye kufuneka isetyenziswe ngokukhuselekileyo. Iyacaphukisa kwaye iyatshisa kwaye inokubangela umonakalo wamehlo, ulusu kunye nenkqubo yokuphefumla. Izixhobo ezifanelekileyo zokuzikhusela ezinje ngeglavu, iiglavu kunye nezikhuselo zobuso kufuneka zinxitywe ngexesha lokusetyenziswa. Landela izenzo zokhuseleko lwaselabhoratri kwaye ugcine, uphathe kwaye ulahle ikhompawundi ngokufanelekileyo. Kwimeko yokunxibelelana ngengozi okanye ukungeniswa, khangela unyango ngokukhawuleza kwaye unike ulwazi oluyimfuneko kugqirha.
