Intshayelelo
I-3,5-Difluorobenzoic acid yi-organic compound. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwale khompawundi:
Umgangatho:
- I-3,5-Difluorobenzoic acid yikristale engenambala okanye i-crystalline powder emhlophe.
- Iphantse inganyibiliki emanzini kwiqondo lokushisa, kodwa i-soluble kwi-solvents eziphilayo ezifana ne-ethanol, i-ether, njl.
- Ikhompawundi inevumba elibukhali elibukhali kwaye liyatshisa.
Sebenzisa:
- I-3,5-Difluorobenzoic acid isetyenziswa kakhulu njengento ebalulekileyo ephakathi kunye ne-reagent kwi-organic synthesis.
- Ikhompawundi ingasetyenziswa kwi-reaction fluorination kunye ne-coupling reaction of aromatics compounds kwi-organic synthesis reactions.
Indlela:
- Indlela yokulungiselela i-3,5-difluorobenzoic acid inokufumaneka ngokuphendula kwe-benzoic acid kunye ne-hydrofluoric acid phambi kwe-catalyst.
- Ngaphantsi kweemeko zokuphendula, i-benzoic acid ixutywe kunye ne-hydrofluoric acid kwaye ishushu, kwaye ukusabela kuqhutyelwa phantsi kwesenzo se-catalyst ukuvelisa i-3,5-difluorobenzoic acid.
Ulwazi ngoKhuseleko:
- I-3,5-Difluorobenzoic acid i-compound ecasulayo enokubangela ukucaphuka ekudibaneni nolusu kunye namehlo, kunye nezixhobo ezifanelekileyo zokukhusela kufuneka zigqitywe.
- Ukunyamekela kufuneka kuthathwe ukuphepha ukudibanisa kunye nee-oxidizing agents ezinamandla kunye nezinto ezinamandla ze-alkaline xa usebenzisa okanye ugcina le ngqungquthela ukukhusela ukuphendula okuyingozi.
- Kuphephe ukusezela umphunga omninzi we-3,5-difluorobenzoic acid, njengoko unevumba elibi.
