Intshayelelo
4-Chloro-3-fluorobenzoic acid.
Iipropati: Inokunyibilika kwizinyibilikisi ezininzi eziphilayo ezifana ne-ethanol, i-ether kunye nekloroform kwiqondo lobushushu begumbi.
Ukusetyenziswa: Ingasetyenziselwa ukulungiswa kwedayi kunye neengubo.
Indlela:
Indlela yokulungiselela i-4-chloro-3-fluorobenzoic acid idla ngokufunyanwa ngokuphendula i-benzoic acid kunye ne-carbon tetrachloride kunye ne-hydrogen fluoride. Okokuqala, i-benzoic acid isabela nge-carbon tetrachloride phambi kwe-aluminium tetrachloride ukwenza i-benzoyl chloride. I-Benzoyl chloride ke isabela nge-hydrogen fluoride kwi-solvent ye-organic ukuvelisa i-4-chloro-3-fluorobenzoic acid.
Ulwazi ngoKhuseleko:
I-4-Chloro-3-fluorobenzoic acid izinzile kwiqondo lokushisa, kodwa ukudibanisa ne-oxidants eqinile kunye nokushisa okuphezulu kufuneka kugwenywe. Izixhobo ezifanelekileyo zokukhusela, ezinjengeeglavu kunye neeglavu, kufuneka zinxitywe xa uphatha ikhompawundi ukuthintela ukudibana nolusu kunye namehlo. Iimeko ezifanelekileyo zokungenisa umoya kufuneka zibonelelwe ngexesha lokusebenza.
