Intshayelelo
I-2,5-bis (trifluoromethyl) i-benzoic acid yi-organic compound kunye ne-chemical formula C9H4F6O2. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:
Indalo:
- 2,5-bis(trifluoromethyl)benzoic acid yikristale engenambala ukuya kumthubi okanye umgubo oqinileyo.
-Phantse i-insoluble emanzini kwiqondo lokushisa, kodwa i-soluble kwii-solvents eziphilayo ezifana ne-ether kunye ne-dichloromethane.
-Unevumba elinamandla lokutya kunye nevumba elibi.
Sebenzisa:
- I-2,5-bis (trifluoromethyl) i-benzoic acid yi-reagent esetyenziswa ngokuqhelekileyo kwi-organic synthesis, engasetyenziselwa ukudibanisa iikhompawundi ezifana neziyobisi, iidayi kunye nezixhobo.
-Ingasetyenziswa njenge-catalyst ye-organic synthesis reactions, njenge-aromatization reactions kunye ne-carboxylation reactions.
-Ukongezelela, isetyenziselwa ukulungiswa kwezinto zombane kunye nokuguqulwa kwendawo yezinto ezibonakalayo.
Indlela yokulungiselela:
- I-2,5-bis (trifluoromethyl) i-benzoic acid inokwenziwa ngokuphendula i-2,5-difluoromethylbenzoic acid kunye ne-trifluoromethylating reagent (njenge-trifluoromethyl chloride).
-Le mpendulo ngokuqhelekileyo iqhutyelwa phantsi kwe-atmosphere ye-inert kwaye isebenzisa i-catalyst phantsi kweemeko ze-acidic okanye ezisisiseko.
Ulwazi ngoKhuseleko:
- 2,5-bis(trifluoromethyl)benzoic acid idla ngokudla kwaye inokubangela ukucaphuka kakhulu kunye nomonakalo xa udibana nolusu kunye namehlo.
-Nxiba izixhobo ezifanelekileyo zokukhusela ezifana neeglavu, iiglasi kunye nempahla yokukhusela ngexesha lokusebenza.
-Le khompawundi kufuneka igcinwe kude nomlilo kunye ne-oxidizing agents, kwaye ifakwe kwisitya esivaliweyo ukukhusela ukudibana nomoya kunye namanzi.
-Iendlela ezifanelekileyo zokhuseleko lwelabhoratri yeekhemikhali kufuneka zilandelwe ngexesha lokusetyenziswa kunye nokugcinwa.
