Intshayelelo
I-2,4-Difluorophenylacetic acid yi-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-2,4-difluorophenylacetic acid:
Umgangatho:
- 2,4-Difluorophenylacetic acid yikristale eqinileyo engenambala ukuya emthubi kunye nevumba elimnandi elingaqhelekanga.
-Ayiguquguquki kwiqondo lokushisa legumbi kwaye i-soluble kwi-solvents eziphilayo ezifana ne-ethanol, i-acetone, i-ether, njl.
- Yiasidi ebuthathaka enokuthi inyibilike kwi-alkalis.
Sebenzisa:
- Inokuthi isetyenziswe njengendawo ephakathi kwiidayi kunye neengubo zokudibanisa iidayi kunye neengubo zemibala ethile okanye iipropati.
Indlela:
- 2,4-Difluorophenylacetic acid inokufumaneka ngokusabela kwe-phenylacetic acid kunye ne-hydrogen fluoride okanye igesi ye-fluorine. Iimeko zokusabela zihlala zifuna i-catalyst kunye nolawulo olufanelekileyo lobushushu.
Ulwazi ngoKhuseleko:
- 2,4-Difluorophenylacetic acid yikhemikhali ekufuneka isetyenziswe ngokukhuselekileyo.
- Xa uphatha, thintela ukudibanisa ngokuthe ngqo kwesikhumba kunye namehlo, kwaye unakekele ukukhusela umgudu wokuphefumula.
- Xa ugcina, kufuneka ugcinwe kwisikhongozeli esingangeni moya, kude nemithombo yomlilo kunye ne-oxidants, kwaye ugweme ukudibana nomoya kunye nokufuma.
- Inkunkuma kufuneka ilahlwe ngokuhambelana nemithetho yendalo esingqongileyo kunye nemimiselo, kwaye akufanele ilahlwe ngokungenamkhethe.
