Isingeniso
4-Chloro-3-fluorobenzoic acid.
Izakhiwo: Ingancibilika kuzincibilikisi eziningi eziphilayo njenge-ethanol, i-ether ne-chloroform ekamelweni lokushisa.
Ukusetshenziswa: Ingasetshenziswa futhi ekulungiseni odayi nezingubo.
Indlela:
Indlela yokulungiselela ye-4-chloro-3-fluorobenzoic acid ivamise ukutholakala ngokuphendula i-benzoic acid ne-carbon tetrachloride ne-hydrogen fluoride. Okokuqala, i-benzoic acid isabela nge-carbon tetrachloride phambi kwe-aluminium tetrachloride ukuze yakhe i-benzoyl chloride. I-Benzoyl chloride ibe isabela ne-hydrogen fluoride ku-solvent ephilayo ukuze kukhiqizwe i-4-chloro-3-fluorobenzoic acid.
Ulwazi Lokuphepha:
I-4-Chloro-3-fluorobenzoic acid izinzile uma kuqhathaniswa nezinga lokushisa elilingana negumbi, kodwa ukuthintana nama-oxidants aqinile namazinga okushisa aphezulu kufanele kugwenywe. Izimpahla zokuzivikela ezifanele, njengamagilavu nezibuko, kufanele zigqokwe lapho uphatha inhlanganisela ukuvimbela ukuthintana nesikhumba namehlo. Izimo ezinhle zokungenisa umoya kufanele zinikezwe ngesikhathi sokusebenza.
