2-Amino-5-fluorobenzoic acid CAS 446-08-2 Isicelo

I-5-Fluoroanthranilic acid yahlanganiswa kusuka ku-2-methyl-4-fluoronitrobenzene njengento yokuqala. Isebenzisa i-Raney nickel njenge-catalyst futhi yehlisa i-catalytic hydrogenation nge-2-methyl-4-fluoronitrobenzene ku-50 °C. Ngemva kokuhlunga i-catalyst ku-Chemicalbook, i-solvent ikhishwa ngokuxutshwa kwe-distillation ukuze kutholwe i-5-fluoro-2-aminotoluene. , bese ifakwa i-oxid nge-potassium permanganate, yenziwe i-asidi futhi ihlungwe ukuze kutholwe umkhiqizo ongahluziwe, futhi ihlanzwe ngemvula ye-alkali-soluble acid ukuze kutholwe umkhiqizo wokugcina ohlosiwe.
