| abstract |
The invention discloses a method for purifying 4-fluoro-2-methoxyaniline, wherein a reaction solution of 4-fluoro-2-methoxyaniline is obtained by reducing reaction of 4-fluoro-2-methoxynitrobenzene, The product is azeotropically taken out by steam distillation, and the solvent is extracted to remove the solvent to obtain light yellow high-purity 4-fluoro-2-methoxyaniline. The method of the invention is simple and easy to operate, the product yield is high, the quality is good, the yield is more than 95%, and the GC content is more than 99.0%. |
