2-Amino-5-fluorobenzoic acid CAS 446-08-2 Daim ntawv thov

5-Fluoroanthranilic acid tau tsim los ntawm 2-methyl-4-fluoronitrobenzene ua cov khoom pib. Nws siv Raney npib tsib xee ua cov khoom siv hluav taws xob thiab ua kom txo qis catalytic hydrogenation nrog 2-methyl-4-fluoronitrobenzene ntawm 50 ° C. Tom qab lim tawm cov catalyst hauv Chemicalbook, cov kuab tshuaj raug tshem tawm los ntawm distillation kom tau 5-fluoro-2-aminotoluene. Tom qab ntawd oxidized nrog poov tshuaj permanganate, acidified thiab lim kom tau cov khoom crude, thiab purified los ntawm alkali-soluble acid nag lossis daus kom tau lub purer kawg lub hom phiaj khoom.
